Mathkour M, Zeoli T, Werner C, Scullen T, Garces J, Keen J, Ware M. Recurring Primary Xanthomatous Hypophysitis Behaving Like Pituitary Adenoma: Additional Case and Literature Review. World Neurosurg 2020; 138:27-34. [PMID: 32081821 DOI: 10.1016/j.wneu.2020.02.055] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Revised: 02/07/2020] [Accepted: 02/08/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Xanthomatous hypophysitis (XH) is the rarest histologic type of primary hypophysitis. It is nonlymphocytic and characterized by an infiltration of the pituitary gland by lipid-laden histiocytes and macrophages. The clinical and radiologic features overlap heavily with pituitary adenomas and are prone to misdiagnosis. We describe a rare case of XH recurrence at 1 year, treated surgically. Moreover, we provide an updated review of the literature to further elucidate useful management and detection strategies. CASE DESCRIPTION A 45-year-old woman presented with a history of menstrual irregularity for 9 months, amenorrhea, galactorrhea, and headache for 2 months duration. Preoperative endocrinologic studies showed increased prolactin levels. Magnetic resonance imaging of the sella showed a cystic lesion with suprasellar extension suggestive of a pituitary adenoma. The patient underwent transsphenoidal resection, showing a thick yellowish colloidal material. Histopathology showed necrotic tissue with no definitive diagnosis and no identified microorganisms. At 2 months after surgery, prolactin levels and menstrual cycle normalized. At 1 year after surgery, her menstrual cycle again became irregular. Repeat magnetic resonance imaging showed a recurrent mass and a second transsphenoidal resection was undertaken. Repeat histopathology was consistent with XH. The patient is 9 years postoperative and is doing well without evidence of recurrence. CONCLUSIONS XH presents similarly to nonfunctional adenomas and diagnosis remains difficult without surgical pathology, requiring meticulous immunohistochemistry to prevent misdiagnosis. Thus, XH should be considered as a rare cause in the differential of disease of the sellar region. Management can parallel that of pituitary neoplasm, with a focus on radiosurgery, re-resection, and high-dose steroids.

Abstract
We present a 69-year-old woman who presented with chronic headaches and was found to have a pituitary mass on MRI, which was biopsied and said to be lymphocytic hypophysitis. The woman was placed on prednisone and followed with routine eye examinations. Two years later, the lesion gradually increased in size and the woman developed a decrease in peripheral vision in the right eye. An MRI showed abutment of the right optic nerve by the mass. A repeat endoscopic transsphenoidal biopsy/resection of the pituitary lesion was performed. Histopathological analysis of the specimen was consistent with diagnosis of xanthomatous hypophysitis (XH). XH is an inflammatory disorder of the pituitary gland characterized by an infiltration of lipid-laden histiocytes, also known as xanthoma cells. The mass was biopsied and a diagnosis of lymphocytic hypophysitis was made. The woman reported improved visual acuity and peripheral vision postoperatively. One year after the second resection, her visual symptoms worsened. Repeat MRI revealed expansion of the residual pituitary tissue. She was referred to the radiation oncology department for external beam radiation therapy and was placed on a maintenance dose of steroids. Since undergoing radiation therapy, her vision has improved slightly and her 3month MRI revealed stable lesion size. This woman illustrates a rare pituitary pathology presented with a literature review of published patients describing xanthomatous hypophysitis. A discussion of the clinical presentation, epidemiology, etiology, diagnosis, histology and treatment is provided.

Abstract
Autoimmune hypothyroidism is a common medical condition. Its revelation by thyrotrophic hyperplasia is an unusual and may be misdiagnosed as a pituitary adenoma. A 35-year-old man is referred to us for endocrinological assessment before surgery of a pituitary macroadenoma with bitemporal hemianopsia. Biological data reveal profound primary hypothyroidism. With thyroid hormone substitution, the thyroid function was normalized. Follow-up magnetic resonance imaging, showed the complete shrinkage of the pituitary mass attesting of a thyrotrophic pituitary hyperplasia. This case highlights the importance of a multidisciplinary assessment of pituitary masses to avoid unnecessary surgery and to prevent consequences of sellar masses.

Abstract
BACKGROUND Primary hypophysitis causes varying degrees of endocrine dysfunction and mass effect. The natural course and best treatment have not been well established. METHODS Medical records of 22 patients who had been diagnosed with primary hypophysitis between January 2001 and March 2013 were retrospectively reviewed. Based on the anatomical location, we classified the cases as adenohypophysitis (AH), infundibuloneurohypophysitis (INH), and panhypophysitis (PH). Clinical presentation, endocrine function, pathologic findings, magnetic resonance imaging findings, and treatment courses were reviewed. RESULTS Among 22 patients with primary hypophysitis, 81.8% (18/22) had involvement of the posterior pituitary lobe. Two patients of the AH (2/3, 66.6%) and three patients of the PH (3/10, 30%) groups initially underwent surgical mass reduction. Five patients, including three of the PH (3/10, 33.3%) group and one from each of the AH (1/3, 33.3%) and INH (1/9, 11.1%) groups, initially received high-dose glucocorticoid treatment. Nearly all of the patients treated with surgery or high-dose steroid treatment (9/11, 82%) required continuous hormone replacement during the follow-up period. Twelve patients received no treatment for mass reduction due to the absence of acute symptoms and signs related to a compressive mass effect. Most of them (11/12, 92%) did not show disease progression, and three patients recovered partially from hormone deficiency. CONCLUSION Deficits of the posterior pituitary were the most common features in our cases of primary hypophysitis. Pituitary endocrine defects responded less favorably to glucocorticoid treatment and surgery. In the absence of symptoms related to mass effect and with the mild defect of endocrine function, it may not require treatment to reduce mass except hormone replacement.

Abstract
We report a case of 41-year-old lady who presented with chronic headache of 6-month duration and a sellar mass with a suprasellar extension on imaging, which was interpreted as pituitary macroadenoma. She had normal pituitary function and visual perimetry. On clinical examination and imaging it was provisionally diagnosed as pituitary incidentaloma due to hypophysitis and she was advised steroid therapy, but underwent transnasal resection of the tumor against suggestion. Histopathological examination revealed combined granulomatous and lymphocytic hypophysitis most likely of autoimmune in origin. Definitive diagnosis of hypophysitis can be made only on histopathological examination. As most cases of autoimmune hypophysitis are surgically treated, patients should be assessed on individual basis for requirement of steroids in postoperative period.

Abstract
A 41-year-old man presented with left optic neuritis (ON) without evidence of other autoimmune disease or hormonal imbalance. MRI showed enlargement of the left optic nerve but no sellar lesion. The patient recovered after steroid therapy but later developed right ON and required treatment again. Follow-up MRI revealed an ill-defined, enlarging sellar lesion with enhancement extending into the right cavernous sinus, and the patient developed symptoms of fatigue and loss of libido. Hormonal studies revealed hypogonadism and hypocortisolism. All laboratory investigation for autoimmune and infectious diseases remained negative. A transsphenoidal biopsy of the lesion revealed lymphocytic hypophysitis. The concomitant development of lymphocytic hypophysitis and optic neuritis suggests a common and likely autoimmune etiology. Visual loss in patients with LYH can sometimes be due to ON rather than compression of the optic apparatus, with significant implications for treatment strategies.

Abstract
Medical therapy of autoimmune hypophysitis with immunosuppressive drugs can be effective to induce remission of the disease by treating both pituitary dysfunction and compression symptoms. We describe the case of a 41-yr-old man with autoimmune hypophysitis in whom prednisone therapy induced remission of the disease but was followed by a sudden relapse after withdrawal. A second trial of corticosteroid was started and succeeded in inducing remission of the disease. Eight months after the second withdrawal pituitary function was restored, pituitary mass had disappeared, only partial diabetes insipidus remained unchanged. Review of the literature identified 30 articles, among case reports and case series, reporting a total of 44 cases of autoimmune hypophysitis treated with glucocorticoids and/or azathioprine. Combining all the cases, medical therapy resulted to be effective in reducing the pituitary mass in 84%, in improving anterior pituitary function in 45%, and in restoring posterior pituitary function in 41%. Clinical aspects of autoimmune hypophysitis are discussed and a possible algorithm for the diagnosis and treatment of the disease is proposed.

Abstract
Hypophysitis is an inflammation of the pituitary gland and includes a heterogeneous group of diseases presenting with impaired pituitary gland function. Hundreds of cases have been reported after Goudie and Pinkerton's initial report on a young postpartum woman who died after progressive lymphocytic infiltration of the adenohypophysis in 1962. A 17-year-old woman presented with a three-year history of headache, galactorrhoea and excessive weight gain. The patient had used oral contraceptives for several years until one year previously. Her examination demonstrated only bilateral heteronymous hemianopsia. Laboratory investigation revealed elevated prolactin and decreased gonadotropin levels. Magnetic resonance imaging showed a sellar mass with suprasellar extension. Surgical removal of the lesion was performed via a transsphenoidal approach. A diagnosis of lymphocytic hypophysitis was confirmed by histopathological evaluation. Hypophysitis is an underestimated disease affecting the pituitary gland. Cases are usually diagnosed as adenomas and treated with surgical removal. This case is presented due to the extremely rare infiltration of the pituitary gland by predominantly lymphocytes.

Abstract
Background. Hypophysitis is an inflammatory disease of the pituitary gland that may mimic pituitary tumors clinically and radiologically. Case Description. We report a case of a xanthomatous hypophysitis initially diagnosed as pituitary adenoma. A 31-year-old woman presented with headache, diabetes insipidus, and amenorrhea. A head CT scan showed no intrasellar changes, while an MRI scan showed a sellar cystic mass. An endocrinological work up revealed mild hypocortisolism and diabetes insipidus (DI). Transsphenoidal surgery was performed. The intraoperative histological examination suggested a pituitary adenoma. The removed tissue showed central necrosis surrounded by accumulation of foamy cells and xanthomatous epithelioid cells. The patient made an uneventful postoperative recovery, Nevertheless, DI persisted and the adenohypophysis hypofunction did not recover. Conclusion. We describe an unusual inflammatory lesion of the pituitary gland mimicking an adenoma. A high level of clinical suspicion of inflammatory disorders is necessary for correct diagnosis and optimal management.

Abstract
Granulomatous hypophysitis (GRH) is extremely rare and commonly presents with chronic inflammatory of the enlarged pituitary gland. In our study, 66-year-old and 57-year-old women, both Chinese, were diagnosed with GRH presenting preoperatively definite imageology characters as pituitary adenoma. The 66-year-old woman presented with a year of headache, half a year of gradual decrease of visual acuity, and one month of right ptosis. Serum prolactin level was slightly elevated. Screening computed tomography (CT) scanning revealed typical low density mass found on the enlarged sella, which demonstrated invasive extension from the sella to the right cavernous sinus by contrast enhanced magnetic resonance imaging (MRI). Consequently, the patient was diagnosed with probable invasive pituitary adenoma. The other 57-year-old woman complained a light headache and had been previously treated as nonfunctional pituitary adenoma in other hospital. Finally these two patients underwent transsphenoidal microsurgery and were diagnosed with GRH according to postoperative histopathology. They then were treated with steroid. During the follow-up, the clinical symptoms such as headache, visual damage, and ptosis vanished, and the mass of the sellae dramatically shrank on repeated MR images. Clinically and radiologically, GRH is a rare sellar entity easily to be misdiagnosed as a pituitary adenoma. Trans-sphenoidal surgery can decompress the optical nerve or oculomotornerve as a therapeutic strategy, and support biopsy or further pathological diagnosis. However, the hormonal therapy should be emphasized both as diagnostic and therapeutic strategies. Conservative and tentative steroid treatment should be performed in preoperative period without acute nerve damage.

Abstract
BACKGROUND Lymphocytic hypophysitis is a disorder of the pituitary gland that presents as a sellar mass lesion and/or hypopituitarism. It causes pituicyte destruction and hypopituitarism and is speculated to have an autoimmune basis. DIAGNOSIS Lymphocytic hypophysitis should be considered in the differential diagnosis of pituitary masses and/or hypopituitarism in females who are pregnant or in the early postpartum period, especially in cases associated with other autoimmune diseases or unusual patterns of hormone deficiencies. A definitive diagnosis requires tissue biopsy. A presumptive clinical diagnosis can be made based on a history of gestational or postpartum hypopituitarism, a contrast-enhancing sellar mass with imaging features characteristic of lymphocytic hypophysitis, a pattern of pituitary hormone deficiency with early loss of adrenocorticotrophic hormone and thyroid-stimulating hormone unlike that typically found with macroadenomas, relatively rapid development of hypopituitarism and a degree of pituitary failure disproportionate to the size of the mass. Symptoms resulting from partial or panhypopituitarism occur in approximately 80% of cases and multiple deficiencies are found in approximately 75% of cases. MANAGEMENT Appropriate management remains controversial. Corticosteroid therapy has been advocated as a means of attenuating inflammation, but given the uncertainty of its efficacy and the known adverse effects, such therapy does not seem justified for most patients. The optimal surgical strategy involves partial resection of the mass to decompress the surrounding structures. All patients with lymphocytic hypophysitis require appropriate replacement therapy for deficient hormones. Long-term follow-up is mandatory to monitor for the development of other hormonal deficits.

Abstract
BACKGROUND Circulating antipituitary antibodies (APA) are markers of autoimmune hypophysitis, which may cause deficient pituitary function. The prevalence of APA in autoimmune thyroid disorders (AITD) is uncertain. OBJECTIVES The aims of this study were 1) to evaluate APA prevalence in a large series of patients with AITD and non-AITD and 2) to investigate the functional significance of APA by assessing pituitary function in APA-positive patients. DESIGN AND SETTING We conducted a health survey on consecutive AITD and non-AITD patients at a tertiary referral center (Department of Endocrinology, Pisa). PATIENTS Subjects, including 1290 consecutive patients with thyroid disorders (961 AITD and 329 non-AITD) and 135 controls, were enrolled in the study. METHODS APA (indirect immunofluorescence), free T(4), free T(3), TSH, and organ-specific autoantibodies were assayed in all patients. Functional pituitary evaluation was performed in most APA-positive patients. RESULTS APA frequency was higher in AITD (11.4%) than in non-AITD (0.9%; P < 0.0001) patients; all control subjects had negative APA tests. APA were more frequently found in Hashimoto's thyroiditis (13%) than in Graves' disease (7.1%; P = 0.05). Of 110 APA-positive AITD patients, 20 (18.2%) had autoimmune polyglandular syndrome, whereas 90 (81.8%) had apparently isolated AITD. APA positivity increased percentage of autoimmune polyglandular syndrome in our series from 10.4 to 13.5%. Of 110 APA-positive patients, 102 were submitted to dynamic testing for functional pituitary assessment; 36 patients (35.2%) had mild or severe GH deficiency (GHD). No additional anterior pituitary hormone deficiencies were found; one patient had central diabetes insipidus. Pituitary abnormalities at magnetic resonance imaging were found in most APA-positive GHD patients. CONCLUSIONS APA are frequently present in patients with AITD. Patients should be tested for APA because positive tests are associated with GHD.

Abstract
Lymphocytic hypophysitis (LyH) is a rare inflammatory disease, considered to be autoimmune. LyH has mainly been reported in females and in relation to pregnancy or the post-partum period. We describe a 73-yr-old woman and a 63-yr-old male who were evaluated at our clinic because of pituitary hormone deficits. Both patients had pituitary masses suggestive of a pituitary adenoma on magnetic resonance imaging (MRI). Transsphenoidal pituitary surgery was performed and histopathological examinations revealed LyH in both cases. Clinical, laboratory, radiological and the histopathological findings in these two patients are discussed in detail. In addition, we report on a 79-yr-old man with partial hypopituitarism and empty sella. Screening of a human pituitary cDNA library with his serum revealed autoantibodies against secretogranin II. This is a protein commonly present in human gonadotrophs, thyreotrophs and corticotrophs. Since the patient selectively showed the corresponding pituitary insufficiencies, we speculate on an autoimmune background. Further studies may ascertain the importance of secretogranin II autoantibodies as markers for LyH.

Abstract
Lymphocytic hypophysitis is an unusual inflammatory lesion that is caused by autoimmune destruction of the pituitary gland. We report a case of 42-year-old man who presented with a 6-month history of severe headache, blurred vision in the right eye, hearing loss, polyuria, polydipsia, and impotence. Medical history showed that he and his mother had osteopetrosis. The results of the physical examination and laboratory tests showed that secondary hypothyroidism, hypogonadism, and hypocortisolism had developed. Central diabetes insipidus was diagnosed by water deprivation test. MRI of the sella showed pituitary enlargement with symmetrical suprasellar expansion, compression of the chiasma, thickened infundibulum, and involvement of both bilateral cavernous sinuses and clivus. Hormonal substitution with hydrocortisone, levothyroxine, and DDAVP resulted in rapid improvement of all symptoms and signs. Transsphenoidal biopsy was diagnostic of lymphocytic hypophysitis. In spite of extensive literature reviewing, we have not been aware of any case of lymphocytic hypophysitis with clivus involvement. The present case represents a variant of lymphocytic hypophysitis which has progressed to involve bilateral cavernous sinuses and the clivus.

Abstract
The relationship between isolated TSH deficiency and hypophysitis was studied. Six patients (five women and one man) with idiopathic isolated TSH deficiency were longitudinally investigated with an interval of 31 to 60 months. Clinical symptoms, laboratory results and endocrine function were investigated as well as pituitary magnetic resonance imaging (MRI) at the start and the end of the study. Clinically, initial symptoms due to hypothyroidism were ameliorated by the thyroid hormone replacement in all patients. Oligomenorrhea newly appeared during the study in three patients, although no other symptoms appeared. Serum fT3 and fT4 levels were within the reference ranges, and serum TSH level and its response to TRH stimulation remained low in all patients. Peak plasma GH level during GRH stimulation was significantly (p<0.03) decreased, at the end of the study as compared with the start. Peak plasma FSH level to LHRH stimulation was significantly (p<0.03) decreased as well as basal FSH level. In contrast, peak of prolactin during TRH stimulation was significantly (p<0.03) increased at the end of the study as compared with the start as well as basal prolactin level. Endocrine features at the end of the study were compatible with those of lymphocytic adenohypophysitis (LAH). MRI of the pituitary gland showed empty sella in one patient and slight swelling in two patients. These findings remained unchanged during the study period. One patient underwent pituitary biopsy, with histological examination showing atypical form of LAH. LAH can cause idiopathic isolated TSH deficiency and can functionally progress to combine dysfunction of the pituitary gland.

Abstract
OBJECTIVES Bilateral carotid artery occlusion associated with lymphocytic hypophysitis is exceedingly rare. We describe this association and review the literature. METHODS The authors describe a 38-year-old woman with a history of severe headaches. Magnetic resonance (MR) imaging showed an intrasellar mass with invasion of both cavernous sinuses. Lymphocytic hypophysitis was diagnosed by transphenoidal biopsy. In the course of the disease, she developed symptoms of cerebral ischemia attributable to bilateral occlusion of her internal carotid arteries in both cavernous sinuses. She underwent bilateral superficial temporal artery-middle cerebral artery bypass surgery. RESULTS The patient experienced progressive neurological recovery after surgery. A literature search revealed no other cases describing this unique association. CONCLUSIONS Bilateral carotid artery occlusion may develop in the course of lymphocytic hypophysitis with cavernous sinus involvement. If indicated, cerebral revascularization should be performed to reverse cerebral ischemia.

Abstract
A 47-year-old man had suffered from prolonged fever for two months without clinical evidence of infection. Blood biochemistry and endocrine dysfunction indicated that he had pituitary insufficiency. Thorough whole body imaging studies merely identified a 22 x 14 mm mass lesion in the sella turcica. Tumor pathology and special cell marker study revealed the infiltration of atypical T-lymphoid cells and concomitant presence of some B-lymphoid cells. The fever subsided gradually following subtotal tumor resection and steroid supplementation. However, the mass lesion had invaded the cavernous sinus and optic chiasma shortly after surgery. Six months after his initial visit, metastasis lesions in the liver, the left adrenal gland, and retroperitoneal lymph nodes were discovered. In contrast to cells in the pituitary, the pathological investigation of the liver mass confirmed it to be exclusively of T-cell origin. Therefore, it is plausible that the pituitary dysfunction was related to an inflammatory process, namely hypophysitis, as well as the T-cell lymphoma. This case exemplifies the rarely noted condition of primary pituitary lymphoma with concomitant hypophysitis. Clinical diagnosis is indiscernible until the occurrence of systemic tumor metastasis.

Abstract
Autoimmune (lymphocytic) hypophysitis is a rare disease that should be considered in the differential diagnosis of any nonsecreting pituitary mass, especially when occurring during pregnancy or postpartum. We have analyzed 370 articles published from January 1962 to October 2004 and identified a total of 379 patients with primary lymphocytic hypophysitis. The present review synthesizes the clinical and research data reported in this body of scientific literature.

Abstract
BACKGROUND Lymphocytic hypophysitis is an autoimmune condition that commonly presents in women of childbearing age as hypopituitarism and a sellar mass. CASE REPORT A 66-year-old woman presented with anterior pituitary dysfunction. Computed tomography imaging revealed a small hypodensity that was not felt to be the cause of the pituitary dysfunction. Eight years later, her vision rapidly deteriorated and MRI showed a pituitary mass lesion causing optic chiasm compression. Histological examination of the partially resected gland revealed evidence of lymphocytic hypophysitis. CONCLUSION Our patient is an example of the variable presentation and course of lymphocytic hypophysitis. Such a long latent period between the initial presentation of adenohypophysial hypofunction and optic chiasm compression due to an enlarging pituitary mass has not been reported.

Abstract
Lymphocytic hypophysitis is a rare inflammatory disorder in the pituitary gland. The lesion is usually confined to the adenohypophysis. Although the involvement of the posterior pituitary gland or the stalk is rare, such patients with diabetes insipidus have been reported. Surgery has been used to make the definitive diagnosis. Recent studies suggest, however, that the pathologic diagnosis may not be necessary always. We reported a case of Lymphocytic hypophysitis managed by methylprednisolone pulse therapy. A 50-year-old premenopausal woman with Lymphocytic hypophysitis and diabetes insipidus was treated with methylprednisolone pulse therapy. Her adenopituitary lesion disappeared and the diabetes insipidus resolved. The optimal management for patients with lymphocytic hypophysitis may be the high index of the suspicion prior to the extensive surgical resection. In addition, methylprednisolone pulse therapy may improve the clinical and MRI findings.

Abstract
Object. The authors review their experience in the treatment of 16 patients with primary hypophysitis.
Methods. A retrospective study was undertaken to review cases of primary hypophysitis. The mean age of the patients was 47 years and there was an equal distribution of sexes. Recent pregnancy and underlying autoimmunity were noted in 50% of the patients. Two patients had undergone previous transsphenoidal operations at other centers, one for prolactinoma and another for hypophysitis. Headache, anterior pituitary deficiency, and suprasellar mass lesions were the most common presenting features. The initial presumptive diagnosis was pituitary adenoma in six patients (37.5%) and inflammatory hypophysitis in 10 (62.5%). Five patients received initial medical therapy for hypophysitis; although three (60%) responded satisfactorily, two (40%) did not and later underwent surgery.
Altogether 13 patients (81.2%) underwent transsphenoidal surgery. The histological diagnoses were lymphocytic hypophysitis in 10 (76.9%) and granulomatous hypophysitis in three (23.1%) of the surgically treated patients. A coexistent Rathke cleft cyst was noted in one patient. There was no death in this series. One patient experienced postoperative cerebrospinal fluid leakage and meningitis. One patient had bilateral internal carotid artery occlusion secondary to inflammatory involvement of the cavernous sinuses and arteritis. This patient recovered and is capable of independent functional activities.
Conclusions. All surgical patients experienced improvement in their headache and/or visual field defects and none had visual deterioration. None of the patients experienced any improvement in endocrine function and all required long-term hormone replacement. Transsphenoidal surgery was a safe and effective treatment especially for visual and pressure symptoms. A postoperative recurrence developed in two patients (15.4%) and the treatment modalities included steroid therapy, repeated surgery, and radiosurgery.

Abstract
Lymphocytic hypophysitis is a rare inflammatory disease of the pituitary gland that is being increasingly recognized as a cause of hypopituitarism. This condition may be due to an autoimmune pituitary destruction which usually occurs in young women during pregnancy or in the immediate postpartum period. We describe a case of cystic pituitary mass in a thirty-eight year-old woman presenting with nausea, vomiting, cold intolerance, blurring of vision and the presence of disagreeable odors for a one-month period. She had secondary amenorrhea and galactorrhea for three months. Combined anterior pituitary stimulation test confirmed the diagnosis of hypopituitarism. Magnetic resonance imaging scan with enhancement showed a huge cystic sellar mass with suprasellar extension and thickening of the pituitary stalk. Transsphenoidal exploration was performed with preoperative diagnosis of pituitary macroadenoma with cystic necrosis. Histological examination revealed lymphocytic hypophysitis characteristic of diffuse, dense lymphocytes and plasma cells infiltration with surrounding interstitial reactive fibrosis. Postoperatively, the patient's olfactory function returned to normal but combined anterior pituitary stimulation test showed persistence of hypopituitarism with mild hyperprolactinemia. Prednisolone, thyroxine and estrogen replacements were started and clinical symptoms were much improved. In summary, we report an extremely rare case of a woman with cystic lymphocytic hypophysitis with cacosmia and hypopituitarism, confirmed by histological examination.

Abstract
Lymphocytic hypophysitis is a rare but important cause of pituitary hypofunction which predominantly affects young women in the peripartum period. It is believed to be an autoimmune disorder with an association with other autoimmune disorders and expression of anti-pituitary cytosolic and anti-nuclear antibodies. Clinically, it presents most frequently with symptoms and signs attributable to pituitary hypofunction, headache, visual disturbance and amenorrhoea. It is difficult to distinguish lymphocytic hypophysitis from a pituitary adenoma on pre-operative imaging and definitive diagnosis rests on histology which classically demonstrates destruction of anterior pituitary acini by an inflammatory infiltrate rich in plasma cells and T lymphocytes. Surgical management therefore plays a crucial role to obtain a histological diagnosis and to relieve pressure effects on the optic apparatus in patients with visual disturbances.

Lymphocytic hypophysitis is an uncommon disease with a variable presentation and unclear pathophysiology. We present the case of a 30 year old woman who presented with features typical of a pituitary macroadenoma. She underwent a transphenoidal resection of the mass and histopathological examination revealed lymphocytic hypophysitis. This case illustrates the difficulty in differentiating pituitary macroadenoma and lymphocytic hypophysitis and the variable presentations of lymphocytic hypophysitis.

Abstract
Inflammatory diseases of the pituitary gland constitute a group of interest because of their scarce frequency, because the disorder presents with symptoms of hypopituitarism and expanding sellar mass and because of their therapeutics implications. We present one case of idiopathic granulomatous hypophysitis, in a 55-years-old patient with daily headaches, panhypopituitarism and a sellar mass lesion. Granulomatous hypophysitis is characterized by granulomas with epithelioid histiocytes and multinucleated giant cells but also shows lymphocyte collections. With respect to immunohistochemistry our results show histiocytes (CD68+) and an heterogeneous inflammatory infiltrate (CD45RO+ y CD20+). We analyze the differential diagnosis with another granulomatous processes, infectious or not infectious, and with the histiocytosis. We examine the possible relation with the lymphocytic hypophysitis.

Abstract
Lymphocytic Hypophysitis is a rare autoimmune disease of the pituitary presenting mainly with features of a mass lesion and loss of pituitary function. Its course is quite unpredictable and its treatment is still controversial as experience in the field remains scarce. We describe a 45 year-old woman with a history of recurrent fever and meningeal symptoms who was referred 3 years later to our department for pituitary insufficiency. Hormonal studies revealed an anterior pituitary deficiency and autoimmune thyroiditis. Pituitary hypertrophy as evidenced by magnetic resonance imaging showed complete regression upon hydrocortisone substitution therapy. Two years later, fever and meningeal symptoms recurred as well as pituitary hypertrophy. Cerebrospinal fluid analysis revealed an aseptic lymphocytic meningitis. Pituitary biopsy confirmed the diagnosis of LH. The patient was started on prednisone 70 mg per day. She improved clinically and radiologically and remained free of symptoms thereafter. At a recent follow up the MRI showed an empty sella turcica. Hereby we illustrate a yet unreported pattern of LH presenting as a recurrent aseptic meningitis. We also describe one of the long-term course of the disease which is still unpredictable.

Abstract
We report a 14 year-old peripubertal girl who presented at our clinic with the primary complaint of delayed puberty. She was asymptomatic except for vague complaints of fatigue. Physical examination was significant for mucosal hyperpigmentation and lack of secondary sexual characteristics. Laboratory evaluation revealed a morning cortisol concentration of <0.1 microg/dl (normal range [n.r.]: 4.3-22.4 microg/dl) and a simultaneous ACTH concentration of 2 pg/ml (n.r. 25-62 pg/ml); FSH 66.8 IU/l (n.r. for age: 1-12.8 IU/l); LH 41.1 IU/l (n.r. for age: 1-12 IU/l); E2 38 pg/ml (n.r. for age: 7-60 pg/ml). She had a flat cortisol response to an ACTH stimulation test. MRI of the pituitary gland failed to reveal a lesion. Plasma renin activity, thyroid function tests, parathyroid hormone, prolactin, IGF-I, IGFBP-3 concentrations and serum electrolytes were normal. However, her urinary sodium concentration was high. She was diagnosed with autoimmune polyglandular endocrinopathy including ovarian failure, adrenal failure and autoimmune anterior hypophysitis presenting as isolated ACTH deficiency. We emphasize that autoimmune etiology should be considered in the differential diagnosis of delayed puberty and ovarian failure and that the presence of other endocrinopathies should be searched for even in asymptomatic patients.

Abstract
OBJECTIVE AND IMPORTANCE Lymphocytic hypophysitis is being recognized with increasing frequency, but the long-term course is not well known. Recurrence of lymphocytic hypophysitis after a long interval has never been reported. CLINICAL PRESENTATION A 53-year-old woman presented with central diabetes insipidus. Magnetic resonance imaging (MRI) revealed an intrasellar lesion. Transsphenoidal biopsy yielded a diagnosis of lymphocytic hypophysitis. Regression of the lesion was confirmed by follow-up MRI. The patient lived normally, with gradual improvement of diabetes insipidus, until she suddenly became aware of a visual defect, which developed into bitemporal hemianopsia 2 years after the biopsy. MRI revealed a larger sellar lesion extending to the hypothalamus. However, the adenohypophysial function remained normal and the mild diabetes insipidus continued unchanged. INTERVENTION Prompt corticosteroid treatment was remarkably effective. The visual defect disappeared during steroid therapy, and a significant reduction of the lesion was revealed by MRI. CONCLUSION It is suggested that long-term follow-up with endocrinological and radiological studies may be necessary in cases of lymphocytic hypophysitis. Recurrent cases should be promptly treated with steroids when a definitive histological diagnosis had been confirmed.

Abstract
OBJECTIVE Lymphocytic hypophysitis and granulomatous hypophysitis are rarely encountered. The aim of this study was to demonstrate their clinical peculiarities among pituitary disorders and to provide an approach for their clinical management. METHODS In a retrospective study, we reviewed our surgical experience with nine patients harboring hypophysitis. The series included six cases of lymphocytic hypophysitis, two cases of granulomatous hypophysitis, and one case with evidence of coexisting lymphocytic and granulomatous hypophysitis. RESULTS A striking similarity of clinical signs was found for our nine patients. Headache or aseptic meningitis, thickening of the sphenoid sinus mucosa, pituitary stalk enlargement, and tongue-shaped extension of the lesion along the basal hypothalamus were characteristic signs. Lymphocytic hypophysitis was not associated with pregnancy in any of the seven cases. No recurrence has been observed in six cases with total removal of the inflammatory tissue. CONCLUSION Lymphocytic hypophysitis and granulomatous hypophysitis represent related inflammatory disorders. Their conspicuous clinical features frequently allow preoperative diagnosis of hypophysitis. In view of their sometimes insidious clinical course, early surgical exploration is justified.

Abstract
A pregnant woman presented with headaches, bilateral decreased visual acuity, and a central scotoma with a superotemporal hemianopic defect in the right eye and a superotemporal hemianopic defect in the left eye, and bilateral temporal optic disk pallor. Neuroimaging revealed an intrasellar mass with suprasellar extension. Biopsy of the lesion revealed lymphocytic hypophysitis (LH). Treatment with steroids produced marked improvement in visual function. The clinical presentation of lymphocytic hypothysitis may mimic pituitary adenoma and the diagnosis should be suspected in any pregnant or postpartum patient with an intrasellar or suprasellar mass.

Abstract
Although magnetic resonance imaging (MRI) characteristics of pituitary gland hyperplasia in primary hypothyroidism have been previously described, the time span necessary for the regression of the hyperplasia in response to acute thyroid hormone (TH) therapy has not been defined. A 26-yr-old woman underwent 131I ablation 11 yr before admission. Intermittent poor compliance to levothyroxine (LT4) therapy led to inappropriately high serum thyroid-stimulating hormone (TSH) for her triiodothyronine (T3) and thyroxine (T4) levels. The patient was investigated to rule out TSH-secreting pituitary adenoma or resistance to TH. On admission, the patient's clinical features and thyroid function tests, as well as thyrotropin-releasing hormone (TRH) and acute T3 suppression tests, were in favor of profound primary hypothyroidism. MRI revealed symmetrical enlargement of the pituitary gland with distinct morphological characteristics of a macroadenoma. The patient began high-dose TH therapy and was rescanned six days later. The follow-up scan revealed a dramatic shrinkage of the pituitary gland. Four weeks later, serum T4 and TSH were within the normal range, and repeat MRI scan of the pituitary at that time showed a normal gland. This case is the first to document dramatic shrinkage of pituitary hyperplasia in long-standing primary hypothyroidism within one week of acute TH therapy. MRI alone is unable to reliably differentiate between a TSH-secreting pituitary adenoma and hypothyroidism-induced pituitary hyperplasia. Dynamic endocrine testing as well as repeat pituitary MRI after a brief TH trial may provide a firm diagnosis in similar cases.
