ABSTRACT

Diagnosis: Osteochondritis Dissecans of the Tarsal Navicular

History: 40 year old female with chronic right dorsal mid foot pain. Patient’s symptoms were relieved with therapeutic injection of the talonavicular joint.

Findings: Axial CT with sagittal reformats through the ankle reveals cortical disruption at the proximal articular surface of the tarsal navicular bone. Multiloculated subchondral cyst adjacent to the cortical defect is noted.

Ddx: Stress fracture (Expect to see partial or complete sagittal fracture line through navicular) Osteonecrosis (Usually see sclerosis and/or collapse of the navicular)

Dxhow: Clinical Course / Symptoms Recovery

Exam: N / A

No MeSH data available.
