Summary
A rare suprasellar xanthogranuloma presented with hypopituitarism and visual field defects. This case highlights the importance of considering xanthogranulomas in suprasellar mass differential diagnoses.
Area of Science:
- Neurology
- Endocrinology
- Pathology
Background:
- Xanthogranulomas are rare tumors typically found in the sella turcica.
- Suprasellar masses can present with diverse neurological and endocrinological symptoms.
Observation:
- A 26-year-old male presented with fatigue, bitemporal hemianopsia, and polyuria, indicating severe hypopituitarism.
- MRI revealed a suprasellar mass with heterogeneous enhancement and T2 hypointensity.
Findings:
- Subtotal tumor removal was performed, with initial suspicion of craniopharyngioma.
- Histopathology confirmed xanthogranuloma, characterized by cholesterol clefts, giant cells, and hemosiderin, but lacking epithelial cells.
Implications:
- This case expands the known locations of sellar region xanthogranulomas to the suprasellar area.
- Xanthogranulomas should be considered in the differential diagnosis of suprasellar masses, even when atypical in location.

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:18Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
