A Case of Calcific Myonecrosis: A Rare Clinical Presentation

Abstract

CASE REPORTthe swelling was multilobulated, fluctuant, and tender, measuring 5 × 2 cm on the right leg's mid-anterolateral aspect (Fig. 1).Neurological examination revealed weak dorsiflexion of the right ankle and eversion of the right foot. The radiograph of the right leg exhibited a homogenous radiopaque lesion over the lateral aspect (Figs 2A and B). MRI is suggestive of myositis ossificans lesion restricted to the lateral and anterior compartment of the right leg with no hypervascularity (Figs 2C and D). Blood tests for liver function, serum calcium, phosphorus, and alkaline phosphatase were all normal. A nerve conduction test revealed a decrease in the conduction velocity of the right superficial and deep peroneal nerves. Tru-cut biopsy results suggested myositis ossificans. An excision biopsy was performed under spinal anesthesia with softtissue tumor and myositis ossificans as differential diagnoses in mind. The pus was extracted and sent for histopathological 1,
