To present four cases of calcific myonecrosis.
Defining the clinical and radiological findings of the entity based on our experience and compare our results with those obtained in the reviewed literature.
Establish the differential diagnosis.
Methods and Materials
We reviewed the cases of calcific myonecrosis diagnosed in a tertiary hospital between September 2004 and September 2011. CASE 1:
- Referred to Functional Unit of Bone Tumours and Sarcomas.
- 20 cm mass occupying the anterolateral region of the leg ( Fig. 1 ).
- Supracondylar femur fracture 34 years ago.
Residual equinus foot.
- Radiography (Rx) ( Fig. 2 ),
magnetic resonance imaging (MRI) ( Fig. 3 ) and computed tomography (CT) were performed ( Fig. 4 ).
Our four cases occurred in men,
average age 62.75 years (range = 54-77).
50% were referred to the Unit of tumours diagnosed of sarcoma,
one case went to the traumatolgy service and the remaining to the emergency room.
There was history of severe traumatic injury in the lower limb in all cases,
average of 24 years ago (range 12-34).
The 50% clearly explained a compartment syndrome,
and the rest reported repeated hematomas.
75% suffered a residual equinus foot. 75% were located in the anterior...
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,
