“…[ 43 ] As detailed in Table 4 , a total of 4 cases reported open craniotomies – among which, 1 patient was well postoperatively (25%)[ 8 ] and the other three had persisting deficits (vision or hormonal insufficiencies). [ 18 48 55 ] By comparison, among the seven cases adopting an endoscopic trans-nasal approach, four patients improved post-operatively (57%),[ 38 43 56 ] two had persistent deficits[ 41 ] (including our case) and the other patient's recovery was complicated by CSF leakage requiring revision surgery. [ 38 ] The rationale behind utilizing an open versus endoscopic surgical route was only explained in two out of the 11 cases (including our case, see Table 5 ).…”

Background:Keratinous or epidermoid cysts (ECs) are encapsulated lesions lined by squamous cell epithelium. They comprise approximately 1% of intracranial lesions. Contrary to dermoid cysts, they lack dermal elements such as sebaceous or apocrine glands and hair follicles. The sellar region is the second most common intracranial site following the cerebellopontine angle. Here, we report a case of EC in a patient who complained of endocrine disturbances. We also performed a systematic review on previously published cases to analyze clinical and radiological characteristics and report the treatment outcomes of suprasellar ECs.Case Description:A 42-year-old woman presented with a one-year history of amenorrhea, weight gain, severe headache, and visual disturbances for 6 months. Work-up identified an elevated prolactin level and a temporal field defect of the right eye. Magnetic resonance imaging (MRI) showed a cystic suprasellar lesion pushing on the optic chiasm. She underwent endoscopic trans-sphenoidal surgery, which confirmed a keratinous cyst on histology. Postoperatively, complete resection was confirmed on imaging. She did well although her hospital stay was prolonged due to diabetes insipidus and hypocortisolism.Conclusion:Chronic endocrine disturbances can be the presenting complaints of a suprasellar EC, whose T1-weighted MRI appearance can be non-specific, mimicking other differential diagnoses, such as a Rathke's cleft cyst. However, the T2-weighted MRI appearances of ECs are generally hyper-intense and lesions show diffusion restriction. Treatment is surgical and yields good outcomes in most cases reported.
