Enterogenous cyst in the fourth ventricle--case report
Abstract:
A 53-year-old male presented with a rare enterogenous cyst in the fourth ventricle associated with repeated ventriculoperitoneal shunt malfunction. Surgical excision of the cyst resolved the shunt problems. Electron microscopy findings of the surgical sample were microvilli covered with electron-dense coating materials, basement membrane, and several intercellular junctional devices, suggesting the cyst was derived from the endodermal structure. The viscous and gelatinous contents of the cyst might be responsible for the shunt malfunction.
Insights
A rare enterogenous cyst in the fourth ventricle caused repeated ventriculoperitoneal shunt malfunction in a 53-year-old male. Surgical removal of the cyst resolved the shunt issues, indicating its role in the malfunction.
Area of Science:
- Neuroscience
- Surgical Pathology
- Medical Device Engineering
Background:
- Enterogenous cysts are rare congenital malformations that can occur in various locations within the central nervous system.
- Ventriculoperitoneal shunts are commonly used to treat hydrocephalus but are prone to malfunction.
Observation:
- A 53-year-old male presented with recurrent ventriculoperitoneal shunt failure.
- Imaging revealed a cyst in the fourth ventricle.
- The cyst's viscous contents were suspected to be the cause of shunt malfunction.
Findings:
- Surgical excision of the fourth ventricle cyst was performed.
- Electron microscopy of the cyst wall showed features consistent with an endodermal origin, including microvilli and basement membrane.
- The cyst's gelatinous content was identified as a likely cause of the shunt malfunction.
Implications:
- This case highlights the importance of considering rare cystic lesions as a cause of ventriculoperitoneal shunt failure.
- Surgical management of the cyst can effectively resolve associated shunt problems.
- Understanding the cyst's composition is crucial for managing complications and preventing recurrence.
