Summary
This case report details a rare dermoid brain cyst in an unusual location, presenting unique radiological findings like a gravity-dependent level on CT and MRI. Surgical exploration confirmed fat, fluid, and hair, offering insights into these complex lesions.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Dermoid brain cysts are congenital tumors, often found in the midline, but rarely in the anterior clinoid process.
- This article presents a unique case of a dermoid cyst originating from the anterior clinoid process.
Observation:
- A 39-year-old male presented with a dermoid cyst projecting into the right frontal lobe.
- Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) showed a low-density lesion with a gravity-dependent level.
- The lesion's location at the anterior clinoid process is highly unusual.
Findings:
- Stereotactic biopsy revealed the gravity-dependent level was composed of fat and fluid layers.
- Craniotomy confirmed the presence of hair within the cyst.
- These findings highlight the characteristic composition of dermoid cysts.
Implications:
- This case expands the understanding of rare intracranial locations for dermoid cysts.
- The unique radiological findings, particularly the gravity-dependent level, aid in preoperative diagnosis.
- Reviewing the literature on radiographic findings and locations of dermoid brain cysts provides valuable diagnostic context.

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
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,...
