Bilateral intraosseous ganglion of the talus

Abstract

A bony cyst that is an intraosseous ganglion of benign nature that includes epiphyseal and metaphyseal zones of large bones. Intraosseous ganglion is an uncommon ganglion in talus and in all the cases described in literature where patient had unilateral cyst and had symptoms over ankle joint. No case has been reported with bilateral talus region causing complication with the subtalar joint. A 28-yr-old male presented to our OPD with complain of pain over bilateral ankle for last 9 months. Although ankle motions were within acceptable norms, painful, the subtalar movement was painfully reduced. The radiographic examination of both the foot and ankle confirmed no abnormalities. MRI testing of bilateral ankle revealed cystic lesion involving posterior aspect of talus communicated with the subtalar joint, measuring (1.6x1.2cm) over right and (1.3x1.0cm) over left side. The patient was treated by multiple drill hole and PRP installation. After three months, the clinical outcome was outstanding, and the patient was able to resume his usual activities with full painless range of motion. Bilateral intraosseous ganglion of talus is incredibly rare. Multiple drill holes or curettage should be employed to treat symptomatic patients.
