CASE HISTORY
Increased uptake left talus anterior aspect on bone scan. Evaluate for osteoid osteoma.
TECHNICAL FACTORS
Long- and short-axis fat- and water-weighted images were obtained before and after contrast administration.
KEY IMAGES
This case has no key images.
CASE FINDINGS
- No osteonecrosis stress injury contusion or fracture is noted in the tarsal bones. No stress injury or Freiberg infraction is seen along the metatarsals. No primary inflammatory arthropathy identified in the intertarsal or tarsometatarsal joints. The metatarsophalangeal joints are unremarkable. No capsulitis or capsular swelling is appreciated.
- Fibrocartilaginous coalition centered on middle facet correlating with scintigraphic uptake.
- Peroneus longus and brevis are normally seen. Tibialis posterior FDL and FHL are also normally seen. The anterior tendons are intact. The plantar fascia demonstrates a normal appearance and contour and there is no plantar fibromatosis. No muscle atrophy or myoedema is seen. No Morton’s neuroma or interdigital bursal swelling is appreciated.
- The collateral ligaments are intact. Plantar plates are well preserved. Flexor and extensor tendons are intact without peritendinitis or tenosynovitis. The Lisfranc ligament is intact as are intermetatarsal ligaments.
CASE CONCLUSION
Fibrocartilaginous coalition centered on middle facet correlating with scintigraphic uptake.
