Abstract
Tuberculosis is an infectious disease that involves any organ. However, the primary pituitary tuberculosis is an extremely rare disease. Intracranial tuberculomas account for 0.15-5% of intracranial space-occupying lesions, of which, pituitary as the primary site is unusual, and easily misdiagnosed as pituitary adenoma. In this setting, the late diagnosis can result in permanent endocrine dysfunction. We report the case of a 50-year-old woman who presented to the neurosurgery outpatient department with complaints of progressively increasing headache and diminished vision over the last year. On the clinical examination, the patient was conscious and oriented. The routine hematological and biochemical workup showed an increased erythrocyte sedimentation rate (ESR) and increased prolactin levels. The radiological working diagnosis was consistent with pituitary macroadenoma. No other radiological and/or clinical clue that could elicit the suspicion of pulmonary or extrapulmonary lesions of tuberculosis was found. The transsphenoidal endonasal tumor excision was done. The histopathology showed numerous epithelioid cell granulomas, Langhans giant cells along with scant necrosis. Ziehl Neelsen staining demonstrated acid-fast bacilli, and the final diagnosis of pituitary tuberculoma was made. We report this rare case of pituitary lesion that may be included in the differential diagnosis of sellar lesions to avoid unnecessary surgical interventions, especially in regions where the disease is endemic.

Abstract
Pituitary tuberculoma is extremely rare, even in endemic regions of tuberculosis and much less frequently as a presentation of pituitary apoplexy. We describe a 25-year-old female presented with sudden onset of headache and vision loss of left eye which mimicking symptoms of pituitary apoplexy. MRI of the pituitary gland showed a rim-enhancing lesion at the intrasellar region extending into the suprasellar area, but absence of posterior bright spot with enhancement of the pituitary stalk. Pituitary hormonal evaluation revealed panhypopituitarism and diabetes insipidus. An urgent transphenoidal surgery of the pituitary gland was undertaken for which the histopathology showed necrotizing granulomatous inflammation with infarcted adjacent pituitary tissue. Despite negative fungal and AFB staining, pituitary tuberculoma was presumptively diagnosed based on imaging, pathology and the high incidence of tuberculosis in the country. After the course of anti-tuberculosis therapy, the clinical findings were dramatically improved, supporting the diagnosis. Pituitary tuberculoma is extremely rare in particular with an apoplexy-like presentation but should be one of the differential diagnosis list of intrasellar lesions in the patient presenting with sudden onset of headache and visual loss. The presence of diabetes insipidus and thickened with enhancement of pituitary stalk on MRI were very helpful in diagnosing pituitary tuberculosis.

Abstract
Background and Importance. Sellar tuberculomas are extremely rare lesions with nonspecific clinical manifestations. The tuberculous infection of the pituitary gland and sellar region is characterized by the presence of an acute or chronic inflammatory reaction and may occur in the absence of systemic tuberculosis. The diagnosis is difficult prior to the surgery. An adequate diagnostic and antituberculous drugs usually result in a good outcome. Clinical Presentation. We report four cases of sellar tuberculoma, 3/1 female/male, age range: 50–57 years. All patients had visual disturbances and low levels of cortisol. Conclusion. The clinical diagnosis of sellar tuberculoma is a challenge and should be suspected when a sellar lesion shows abnormal enhancement pattern and stalk involvement, and absence of signal suppression in FLAIR.

Abstract
Tuberculosis, a common cause for chronic intracranial infections can mimic varied intracranial pathologies including tumours. Pituitary tuberculomas are rare lesions and are often diagnosed pre-operatively as pituitary tumours. We report a case of a 31-year-old lady with a sellar-suprasellar lesion who presented with panhypopituitarism. The patient underwent a trans-nasal, trans-sphenoidal surgical decompression of the lesion. Histopathology revealed a tuberculous lesion in the pituitary. The characteristic radiological features of sellar tuberculomas are discussed along with a review of literature. Atypical sellar radiology in the presence of a thickened pituitary stalk could point to pathology other than pituitary adenoma, possibly a chronic inflammatory condition like tuberculoma.

Abstract
A 37-year-old woman presenting with galactorrhea and menstrual irregularity due to an intrasellar lesion of the pituitary gland underwent transsphenoidal surgery for histopathological diagnosis and removal of the lesion. Histological findings were consistent with a tuberculoma. The post-operative course was satisfactory with resolution of galactorrhea and improved ovulatory cycle. The patient was successfully treated with a combination of surgical resection and anti-tuberculous therapy for one year, which resulted in hormonal and tuberculosis control. This patient appears unique regarding the location of the lesion and the dramatic response to surgical treatment. Although differential diagnosis of inflammatory pathologies of the intrasellar region presents difficulties, this patient demonstrates that tuberculoma should be considered.

Abstract
Primary pituitary sarcoma in the absence of previous radiation therapy is very rare, only eight cases having been reported. We present the first reported case of sclerosing epithelioid fibrosarcoma of the pituitary, a 56-year-old woman presenting with diplopia and panhypopituitarism. Magnetic resonance imaging showed a 1.2 x 0.4 x 0.5-cm sellar mass invading the right cavernous sinus. Despite surgery and radiation therapy, our patient developed intracranial metastases and died 2 years after the initial diagnosis. Sclerosing epithelioid fibrosarcoma is an infrequently occurring, distinct variant of soft tissue fibrosarcoma. Its immunophenotype includes vimentin and occasionally CD-34, B cell lymphoma-2, S-100 protein, or keratin expression. Although initially thought to be a low-grade lesion, sclerosing epithelioid fibrosarcomas may also behave in a high-grade manner.

Abstract
Through a case of sellar and suprasellar tuberculoma which presented with central diabetes insipidus, the authors report the frequency of pituitary tuberculoma, its physiopathology, clinical presentation hormonal and radiological findings thus management and evolution. A 42 years old woman, with a history of erythema nodosum, presented with polyuria polydipsia (PUPD), amenorrhea and galactorrhea. Endocrine investigations showed central diabetes insipidus, elevated serum prolactin levels and cortisol failure. Magnetic resonance imagining scans (MRI) revealed a nodular thickening of the pituitary enlargement and loss of posterior pituitary hypointensity signal. Etiologic inquiry has removed the diagnosis of sarcoidosis, Langerhan's histosis, autoimmune hypophysitis and sellar metastasis. The history of erythema nodosum, the positivity of tuberculin skin test and the presence of koch bacillus in the bronchial fluid after culture led to a diagnosis of tuberculosis. Treatment was started with four drug antitubercular chemotherapy regimen for 2 months, and tow drug antitubercular chemotherapy regimen for 16 months. This treatment is associated with hydrocortisone, desmopressin nasal spray and bromocriptine. Under treatment, there was an improvement in clinical condition, disapearence of headache, PUPD and galactorrhea thus normalization of prolactin. A follow-up MRI, 8 months later, showed that pituitary lesion has been completely removed, suggesting our clinical and biology presumption. Pituitary tuberculosis is rare, however, when encountered, they may present a diagnostic difficulty. Accurate diagnosis and management is important because pituitary tuberculoma is curable.

Abstract
BACKGROUND Optochiasmatic tuberculomas are very rare lesions. They can occur with concomitant tuberculous meningitis, and pulmonary tuberculosis or as the only manifestation of the disease. The authors present a case of optic pathways tuberculoma with radiologic appearance simulating an optic pathways glioma. CASE DESCRIPTION We report a case of a 20-year-old man with mental retardation due to anoxic encephalopathy who developed a sudden bilateral amaurosis. He also presented with diabetes insipidus, panhypopituitarism, right proptosis, and chemosis. Computed tomography (CT) and magnetic resonance imaging (MRI) showed an enhancing lesion in the optochiasmatic region extending to both optic nerves, with a mass in the right orbit, mimicking an optic pathways glioma. There was no other evidence of systemic involvement of the tuberculosis. The lesion was explored through a right pterional transylvian approach with opening of the optic canal and orbital roof, and a biopsy and an internal decompression were performed. Histopathological studies demonstrated a granulomatous lesion with central caseous necrosis with acid-fast bacilli. The patient improved after treatment with tuberculostatic drugs, but vision recovery could not be achieved. CONCLUSIONS Visual compromise in tuberculosis is associated with hydrocephalus, optical neuritis or tuberculomas involving the optic pathways. Reviewing the literature on tuberculomas of the optochiasmatic area, we could not find any other case with such extensive involvement of the optic pathways that was radiologically suggestive of an infiltrating glioma. Histopathological studies remain crucial in the diagnosis of intrinsic expansive processes of the optochiasmatic region.

Abstract
Tuberculomas involving the hypophysis cerebri are extremely rare lesions, and these may occur even in the absence of systemic tuberculosis. This report presents the clinical data of 5 patients harbouring tuberculomas of the pituitary gland. Sellar tuberculomas commonly mimic pituitary adenoma. Histological diagnosis of a sellar lesion is mandatory irrespective of the clinical presentation and radiological findings. A history of extracranial tuberculosis in the past associated with radiological findings like leptomeningeal enhancement, parenchymatous brain tuberculomas or a thickened pituitary stalk on contrast MRI, are indicative of the possibility of a sellar tuberculoma. The aim of surgery is tissue diagnosis and tumour debulking. The response to long-term antituberculous chemotherapy is excellent. There is often a complete resolution of the granuloma and a satisfactory recovery of visual and endocrinological function.

Abstract
Pituitary tuberculomas are extremely rare lesions, with only few cases described in the literature, usually mistaken as pituitary tumors. Its heterogeneous clinical and imaging profile preclude preoperative diagnosis which ultimately relies on the histopathological examination. We describe a 46 years old woman who presented with an episode of confusion and hypopituitarism with no evidence of systemic tuberculosis. Computed tomography (CT) showed a central calcified and enhancing sellar mass. Magnetic resonance imaging (MRI) showed a sellar mass with suprasellar extension and associated optic chiasm compression. She was submitted a craniotomy for biopsy and resection. A caseous material was found at the center of the lesion involved by a thick wall. Due to the wall adherence to the optic chiasm and the inflammatory aspects of the lesion, subtotal removal was achieved and the patient followed on anti-tuberculous and hormonal replacement therapy. Sellar tuberculomas should be considered in the differential diagnosis of sellar tumors in order to offer appropriate treatment.

Abstract
OBJECTIVE To analyse clinical and/or laboratorial preoperative hormonal dysfunction, of the nonpituitary intracranial lesions from midline and parasellar area. METHOD Forty-four patients were evaluated with nonpituitary intracranial lesions, who had images studies (computed tomography or magnetic resonance) and preoperative basal hormonal level; 16 had preoperative hypothalamus-hypophysial function tests (megatests). These patients were divided in two groups. Group I - 34 lesions from midline: 11 craniopharyngiomas, 8 meningiomas, 3 germinomas, 3 tumors of sphenoid sinus, 2 empty sella syndrome, 2 pylocitic astrocytomas, 1 giant aneurysm, 2 mucoceles, 1 III ventricle diverticulum and 1 Rathke's cleft cyst; Group II - 10 lesions from parasellar area: 9 meningiomas and 1 giant aneurysm. RESULTS In group I, 25/34 (73.5%) patients showed laboratorial hormonal deficit (14 without clinical manifestations) 18/34 (52.9%) hyperprolactinemia (5 with galactorreia) and 8 (53.3%) showed growth hormone deficiency in 15 megatests available in this group; 3 (8.8 %) patients presented central diabetes insipidus (CDI). In group II, 6/10 (60%) patients showed laboratorial hormonal deficit (5 without clinical manifestations), 1 (10%) hyperprolactinemia and 1 growth hormone deficiency (single megatest realized in this group); no patient had preoperative CID. CONCLUSIONS The presence of nonspecific or poorly valorized clinical manifestations, does not indicate absence of hormonal dysfunction; in this present serie, 19/38 (50%) patients with laboratorial abnormalities, didn't show clinical manifestations. Hormonal dysfunction is frequent in sellar and perisellar nonpituitary lesions, specially involving midline.

Abstract
Tuberculous involvement of the pituitary gland is rare. We report a unique case of a composite lesion consisting of pituitary adenoma and intrasellar tuberculoma. A 24-year-old lady presented with features of acromegaly and amenorrhea. Serum growth hormone levels were found to be raised. Radiological investigations were consistent with a pituitary adenoma. Decompression of the lesion was done through trans-sphenoidal approach. Histological examination revealed a growth hormone secreting pituitary adenoma in association with a granulomatous lesion suggesting of pituitary tuberculoma. No other evidence of tuberculosis was found in the brain or spinal cord. This type of dual pathology has been reported only once in the earlier literature.

Abstract
OBJECTIVE Intrasellar tuberculomas are rare and only few case reports have been described in the literature. We report a series of 18 cases of histologically proven intrasellar tuberculomas, which, to the best of our knowledge, is the largest series in the English literature. METHODS A total of 1143 pituitary lesions, between 1984 and June 1999, were operated for various reasons in our institute. Of these, 18 cases were histopathologically proven intrasellar tuberculomas. The clinical profile was reviewed in detail. Radiological data and histopathological slides were also reviewed. RESULTS The age ranged from 8 to 43 years (average 23.6 years) with a female preponderance. The duration of symptoms varied from 15 days to 2 years (average 4 months), the most common symptoms being headache followed by decrease or loss of vision. Five patients had features of pan-hypopituitarism whereas three had raised prolactin (PRL) levels. In six patients, both sella as well as sphenoid sinus were involved. In one patient the lesion was extending from the sella over the clivus. Clinically as well as radiologically, these lesions were mistaken for pituitary adenomas except for one case where tuberculoma was suspected on imaging. In three patients, there was past history of pulmonary tuberculosis, in one patient of tuberculous meningitis, and in one patient, of spondilytis of the spine. In one patient there was cervical lymphadenopathy along with features of acromegaly (also proved by high levels of serum growth hormone) and radiology revealed a pituitary pathology. Microscopic examination of the excised lesion revealed a composite lesion consisting of a pituitary adenoma and tuberculoma, which has not been documented in literature to date. One patient died during the hospital stay. All the other patients were put on antitubercular chemotherapy following surgery and had good outcomes. CONCLUSION Intrasellar tuberculomas are rare. These may be suspected in female patients especially if radiological imaging shows involvement of paranasal sinuses and pituitary fossa along with thickening of pituitary stalk. Simultaneous involvement of clivus may also be an additional feature. The incidence of pituitary tuberculosis is likely to increase with a rise in the incidence of AIDS.

Abstract
OBJECTIVE AND IMPORTANCE Hypophyseal tuberculomas are extremely rare lesions. The recognition of hypophyseal tuberculomas in the differential diagnosis of pituitary tumors is important, even with no evidence of systemic tuberculosis. CLINICAL PRESENTATION A 27-year-old female patient presented with continuous, dull, generalized headaches and amenorrhea, with no history of visual diminution, galactorrhea, or endocrinological abnormalities and no evidence of systemic tuberculosis. The patient exhibited a normal water balance, without polyuria or polydipsia. A gynecological examination, including an endometrial biopsy for amenorrhea, did not reveal any abnormalities. Perimetric and endocrinological examination results were normal. Contrast magnetic resonance imaging revealed a dense enhancing intrasellar mass, with thickening of the pituitary stalk. INTERVENTION Sublabial rhinoseptal transsphenoidal decompression of the lesion was performed. The histopathological features were consistent with a diagnosis of tuberculoma, and acid-fast bacilli were demonstrated in the surgically removed tissue with Ziehl-Neelsen staining. As soon as the histopathological features were known, the patient underwent a lumbar puncture for cerebrospinal fluid analysis, which indicated normal findings. An intradermal tuberculin test yielded negative results. The patient was treated with medical therapy for 18 months, and complete resolution of the lesion was observed in follow-up examinations. CONCLUSION Hypophyseal tuberculomas are often mistaken for pituitary adenomas. The finding of a thickened pituitary stalk in contrast magnetic resonance imaging scans may be useful for the differentiation of these lesions from pituitary adenomas. Direct radiosurgery is not an appropriate primary treatment method for pituitary adenomas and is principally restricted to elderly, medically unfit patients with microadenomas and patients with residual or recurrent tumors after microsurgery. It is contraindicated for patients who exhibit a thickened pituitary stalk in contrast magnetic resonance imaging scans.

Abstract
The differential diagnosis of nonpituitary sellar masses is broad; differentiating among potential etiologies may not always be straightforward because many of these lesions, tumorous and nontumorous, may mimic the clinical, endocrinologic, and radiologic presentations of pituitary adenomas. This article provides an overview of the clinical and radiographic characteristics of both pituitary tumors and the nonpituitary lesions found in the sellar/parasellar region and discusses, in detail, the specific nonpituitary origins of the sellar masses.

Abstract
This article reviews the complex anatomic relationships between structures in the sellar and parasellar regions. Normal anatomy and the normal imaging spectrum are reviewed, with emphasis on the diversity of pathology that originates from this region. Both CT and MR imaging may be used to evaluate the sellar and parasellar regions. This article discusses how modern imaging techniques enable characterization of the many lesions that alter the structure and function of normal sellar and parasellar anatomy.
