Abstract:
We describe a rare case of intraosseous ganglion arising in the metatarsal bone. Radiographs revealed an osteolytic lesion with a fracture in the third metatarsal bone. A biopsied specimen exhibited hyaline fibrous tissue with marked myxoid change. Gadolinium-enhanced MRI, which revealed the network-like enhancement of the rim of the lesion and polycystic lesions adjacent to the joint, was helpful in making a diagnosis of intraosseous ganglion.
Insights
This case report details a rare intraosseous ganglion in a metatarsal bone, identified by imaging and biopsy. Early diagnosis of this bone lesion is crucial for effective treatment.
Area of Science:
- Orthopedic Surgery
- Radiology
- Pathology
Background:
- Intraosseous ganglia are rare cystic lesions originating within bone.
- Metatarsal bone involvement is exceptionally uncommon.
Observation:
- A patient presented with an osteolytic lesion and fracture in the third metatarsal bone.
- Radiographs and biopsy confirmed a lesion with hyaline fibrous and myxoid changes.
Findings:
- Gadolinium-enhanced MRI demonstrated characteristic network-like rim enhancement and adjacent polycystic lesions.
- These imaging findings were key to diagnosing the intraosseous ganglion.
Implications:
- This case highlights the importance of advanced imaging like MRI in diagnosing rare bone pathologies.
- Accurate diagnosis of intraosseous ganglia is vital for appropriate orthopedic management and preventing complications.
