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.
- Male,
55 years.
- 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).
- Surgical treatment (Fig. 5).
- Anatomic Pathology (AP): muscle necrosis and calcifications.
- No complications nor recurrence.
CASE 2:
- He went to the Traumatology department.
- Male,
64 years.
- Slowly progressive growing tumour of 25cm in the anterolateral region of the leg.
- Fractured tibia 12 years ago.
Repeated hematomas and residual equinus.
- Rx (Fig. 6) and MRI (Fig. 7) were compatible with calcific myonecrosis.
- Expectantly.
- Post-traumatic fistula in 3 years that required surgery.
- AP: calcific myonecrosis.
- Repeated infections and chronic fistula.
CASE 3:
- Referred to Functional Unit of Bone Tumours and Sarcomas.
- Male,
34 years.
- Soft tissue mass about 15 cm in the anterolateral region of the leg (Fig. 8).
- Fracture of tibia and fibula 12 years ago complicated with compartment syndrome.
Residual equinus.
- Rx (Fig. 9),
TC (Fig. 10) and MRI (Fig. 11) were performed.
- Surgery.
- AP: calcific myonecrosis.
- Recurrent infections and chronic fistula.
CASE 4:
-Came to the emergency.
-Male,
77 years.
- Pyomyositis in the posterior left leg.
- Fracture of tibia and fibula 30 years ago complicated with compartment syndrome.
- Rx compatible with calcific myonecrosis (Fig. 12).
- Surgery.
- AP: infected calcific myonecrosis.
- No complications nor recurrence.
Data are collected in Table 1,
Table 2 and Table 3.
Subsequently we did a literature research finding about 40 reported cases.
We descriptively compare their results and try to establish an imaging based limited differential diagnosis.
