[Pituitary cryptococcoma: a strange case of secondary granulomatous hypophysitis].

Hypophysitis is a pathology with low incidence and prevalence. Likewise, deep fungal infections in immunocompetent patients also represent a rare phenomenon. Even rarer is the case described below, where these two mentioned elements are combined, namely: pituitary cryptococcoma or granulomatous hypophysitis caused by said pathogen in a host without altered immune response.

Risk Factors Related to Transient Diabetes Insipidus Development Following Transsphenoidal Pituitary Adenoma Resection: A Multicentric Study.

Objective: To analyze and find risk factors associated with developing transient diabetes insipidus (DI) using a multicenter case series after trans-sphenoidal surgery.

Methods: Medical records of patients who underwent trans-sphenoidal surgery for pituitary adenoma resection between 2010 and 2021 at 3 different neurosurgical centers by 4 experienced neurosurgeons were retrospectively analyzed. The patients were divided into 2 groups (DI group or control group).

Suprasellar chordoid glioma: a report of two cases.

Chordoid glioma (CG) is considered a slow growing glial neoplasm. We report two new cases with endocrinological presentation, management and outcome. Case reports: 1) An 18 year-old female patient was admitted due to headaches, nausea and vomiting and visual abnormalities.

[Pituitary spindle cell oncocytoma].

Spindle cell oncocytoma is an infrequent benign non-endocrine sellar neoplasm. Due to its similar morphology to pituitary adenomas, consideration of this differential diagnosis would conduce to a more careful surgical approach in order to avoid intraoperative bleeding and aiming to a complete resection, on which depends long-term outcomes. We present the case of a 60-year-old male who complained about visual abnormalities, with computerized visual field confirmation.

Tarlov cysts: endoscope-assisted obliteration of the communication with the spinal subarachnoid space.

Background And Objective: The physiopathology of Tarlov or perineural cyst (PC) symptoms is unknown, but probably its filling and distention with spinal cerebrospinal fluid makes them symptomatic. The objective of this study is to describe the endoscope-assisted obliteration of the communication between PCs and the spinal subarachnoid space (SSS).

Patients And Methods: From 2007 to 2011, four male and two female patients (median age: 45 years) with PCs were treated.

Germinoma with involvement of midline and off-midline intracranial structures.

Germinomas are malignant intracranial germ tumors, usually found in suprasellar regions. Less than 10% are localized in off-middle structures, and synchronous involvement of both structures has only exceptionally been published. A case of an 18-year-old male patient with progressive right-sided hemiparesis and panhypopituitarism was reviewed.
