Conclusion
Calcific myonecrosis is a rare condition of post-traumatic origin and late onset.
It was first described in 1960 by Gallie and Thomson.
It is characterized by the formation of a soft tissue tumour partially calcified and almost exclusively located in the leg.
The pathogenesis is unknown and the hypotheses most frequently postulated associate it with ischemic events and nerve damage (especially peroneal nerve damage).
The Rx and CT image of a fusiform soft tissue tumour in the leg,
replacing a muscle or muscle group,
with necrohaemorragic content and laminar peripheral calcifications associated with a history of trauma in the region: allow the accurate diagnosis of calcific myonecrosis without biopsy,
frequent cause of complications.
The isolated MRI,
less sensitive and specific delimiting the almost pathognomonic pattern of calcification,
may lead to misdiagnosis of soft tissue sarcomas.
