Summary
This study reports a rare frontal endodermal cyst (EC) in the brain, a lesion typically found in the spine. Complete surgical removal led to full recovery, highlighting its importance in neurosurgery.
Area of Science:
- Neurosurgery
- Neuropathology
Background:
- Endodermal cysts (EC) are rare central nervous system lesions, predominantly spinal.
- Intracranial EC are uncommon, with supratentorial locations being exceptional.
Observation:
- A 62-year-old male presented with altered mental status after head trauma.
- CT revealed a large frontal cyst with significant midline shift.
- Cyst fluid was milky with high protein; MRI confirmed the lesion.
Findings:
- Complete surgical resection of the frontal EC was achieved.
- Pathological examination confirmed a typical endodermal cyst.
- The patient recovered fully with no recurrence on follow-up MRI.
Implications:
- Supratentorial endodermal cysts are exceptionally rare but require consideration.
- Differential diagnosis can be challenging based on imaging alone.
- Radical surgical excision is the recommended treatment to prevent recurrence.

01:28Urologic Endoscopic Procedure: Cystoscopic Examination
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
01:21Smooth Endoplasmic Reticulum
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
