This case study details a rare cervical intramedullary epidermoid cyst with liquid contents, presenting unique MRI findings that mimicked an arachnoid cyst. This highlights the diverse presentations of these benign spinal tumors.
Area of Science:
- Neurology
- Neurosurgery
- Pathology
Background:
- Intramedullary spinal epidermoid cysts are rare, accounting for less than 1% of intramedullary tumors.
- These benign growths arise from ectopic embryological tissue within the spinal cord.
Purpose of the Study:
- To report an unusual case of a cervical intramedullary epidermoid cyst with liquid contents.
- To discuss the diagnostic challenges posed by atypical MRI findings.
Main Methods:
- Case presentation of a 40-year-old patient with progressive neurological deficits.
- Magnetic Resonance Imaging (MRI) for lesion characterization.
- Histopathological examination of the surgically excised cyst.
Main Results:
- MRI revealed a C2-C3 intramedullary lesion with T1 hypointensity and T2/FLAIR hyperintensity, showing rim enhancement.
- Histopathology confirmed an epidermoid cyst with epidermal lining and keratinous material.
- The cyst contained clear, liquid contents, an uncommon finding.
Conclusions:
- Intramedullary epidermoid cysts can rarely present with liquid contents.
- Atypical MRI features can mimic other cystic lesions, such as arachnoid cysts.
- Accurate diagnosis relies on integrating imaging findings with histopathological confirmation.

Exocrine Glands: Methods of Secretion
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine glands...
Cerebrospinal Fluid
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain.
