Summary
This study presents a rare case of intracranial osteochondroma in the middle fossa. Bone scintigraphy proved valuable for detecting this rare skull base tumor.
Area of Science:
- Neurosurgery
- Oncology
- Radiology
Background:
- Intracranial osteochondromas are rare bone tumors, often presenting with subtle symptoms.
- Diagnosis can be challenging due to their infrequent occurrence and varied presentation.
Observation:
- A 41-year-old male presented with a five-year history of double vision, right abducens palsy, and ipsilateral exophthalmos.
- Imaging revealed mottled calcification and an irregularly shaped high-density area in the right middle fossa.
- Bone scintigraphy showed abnormal uptake, aiding in tumor detection.
Findings:
- Histological examination confirmed the tumor as an osteochondroma.
- Subtotal tumor removal was achieved via frontotemporal craniotomy.
- The patient recovered and returned to work post-surgery.
Implications:
- This case highlights the importance of considering rare diagnoses like osteochondroma in patients with cranial nerve deficits.
- Bone scintigraphy is a valuable tool for identifying intracranial osteochondromas.
- Surgical intervention can lead to favorable outcomes for patients with this condition.
