Characteristics and factors influencing hypothalamic pituitary dysfunction in patients with craniopharyngioma

Background

Craniopharyngioma is a benign tumor originating from the sellar region. Damages in this area caused by the tumor itself, surgery, or radiotherapy may result in severe hypothalamic-pituitary dysfunction (HPD) and eventually lead to a significant impairment in the long-term quality of life of patients. This study aimed to investigate the characteristics of HPD in patients with adamantinomatous craniopharyngioma (ACP) or papillary craniopharyngioma (PCP) and to identify the factors affecting HPD after surgery.

Methods

In this single-center retrospective study, a total of 742 patients with craniopharyngioma were included. The neuroendocrine function of these patients before and after surgery was investigated. The differences in hypothalamic-pituitary function between the ACP and PCP groups were compared. The factors influencing the aggravation of HPD after surgery were identified.

Results

The median follow-up after surgery was 15 months. Before surgery, the proportion of patients with diabetes insipidus (DI) and hyperprolactinemia in the PCP group was significantly higher than that in the ACP group (P<0.01), and the proportion of patients with adrenocortical hypofunction in the PCP group was significantly lower than that in the ACP group (P=0.03). Most cases of ACP originated in the sellar region, while most cases of PCP originated in the suprasellar region (P<0.01). More patients experienced adenohypophyseal hypofunction, DI, and hypothalamic obesity at postoperative follow-up than at onset in both the ACP and PCP groups (both P<0.01), with a higher increase observed in the ACP group (P<0.01). Older age at CP onset, tumor recurrence or progression, and ACP type were risk factors for postoperative aggravation of HPD in CP patients.

Conclusion

Surgical treatment significantly aggravated HPD in both the ACP and PCP groups, but the specific characteristics and risk factors leading to aggravation were different between the two groups.

Endocrine Disorder in Patients With Craniopharyngioma

Craniopharyngioma is an intracranial congenital epithelial tumor growing along the pathway of the embryonic craniopharyngeal tube. The main clinical symptoms of patients with craniopharyngioma include high intracranial pressure, visual field defect, endocrine dysfunction, and hypothalamic dysfunction. At present, the preferred treatment remains the surgical treatment, but the recovery of endocrine and hypothalamic function following surgery is limited. In addition, endocrine disorders often emerge following surgery, which seriously reduces the quality of life of patients after operation. So far, research on craniopharyngioma focuses on ways to ameliorate endocrine dysfunction. This article reviews the latest research progress on pathogenesis, manifestation, significance, and treatment of endocrine disorders in patients with craniopharyngioma.

Craniopharyngioma in a young woman with symptoms presenting as mechanical neck pain associated with cervicogenic headache: a case report

Background: Craniopharyngioma is benign neoplasm thought to be caused by mal-development, which occurs in both children and adults in the sellar and suprasellar regions of the brain. Typical manifestations in adults are visual and endocrine system symptoms followed by signs and symptoms of increased intracranial pressure (i.e., headache). The management of this rare condition is complex and requires life-long surveillance by a multidisciplinary team of health-care professionals.Objective: To present a rare clinical presentation of craniopharyngioma mimicking nonspecific neck pain usually associated with cervicogenic headache recognized by a physiotherapist in a direct access setting as a condition requiring medical referral.Case Presentation: This case report describes the history, examination findings, and clinical reasoning used in the initial examination of a 33-year-old female with neck pain and cervicogenic headache as chief complaints. Several key indicators in the patient presentation warranted further and urgent investigation: 1) the recent onset of a "new-type" headache; 2) the phenotype headaches change; 3) the rapid progression of the symptoms; 4) the presence of associated neurological signs and symptoms; and 5) the worsening of the symptoms during Valsalva-like activities. The decision was made to refer the patient for further evaluation. An MRI revealed a craniopharyngioma. After a surgical removal of the tumor mass, the patient participated in a rehabilitation program and reached a full recovery after 6 months.Conclusion: This case report highlights the need of more research regarding red flags and warning signs during examination of in the head-neck region, and the central role of primary care clinicians such as physiotherapists in differential diagnosis of life-threatening conditions.
