Introduction: PVNS is a locally aggressive synovial proliferative disorder of unknown etiology and has been described in the foot and ankle in previous literature. A case of PVNS in the talus has been described in a patient treated for ipsilateral calcaneal chondral lesion.
Case Report: A 56 year old male presented with pain in his left ankle of 4 months duration. On investigation, he was found to have a well defined lytic lesion in the left calcaneum on x-ray. MRI showed a hyper intense lesion on T2WI. A needle biopsy revealed chondrogenic tumor which was managed by extended curettage. At 12 months follow up, patient presented with recent onset pain over the anterior aspect of left ankle which showed hypo density over the supero-anterior aspect of the talus and MRI showed ill defined hypo intense lesion on T2WI and hyper intense lesion on T1WI. The lesion increased in size on repeat MRI 6 weeks later. He was managed with synovectomy and debridement with core needle biopsy of talus. Histopathological examination revealed features consistent with PVNS. Patient remains asymptomatic at 1 year follow up after surgery.
Conclusion: A double primary lesion although rare, does exist and any recurrence should be viewed at with equal degree of suspicion as the primary lesion.
