Intraosseous pseudotumour of the talus in a child with severe haemophilia

Complications of Muscle Hematomas in Hemophilia

Prevention is essential for avoiding the complications of muscle hematomas (compartment syndrome, pseudotumors and peripheral nerve lesions) in hemophilic patients. This is achieved through early diagnosis of muscle hematomas and proper long-term hematological treatment until they have resolved (confirmed by image studies). Ultrasound-guided percutaneous drainage could be beneficial in terms of achieving better and faster symptom relief. Acute compartment syndrome (ACS) requires emergency surgical treatment (decompression fasciotomy). As for pseudotumors, the biopsy will help us confirm the diagnosis and rule out true tumors (chondrosarcoma, liposarcoma, synovial sarcoma) that sometimes mimic hemophilic pseudotumors. Surgical removal of hemophilic pseudotumors is the best solution. As alternatives, there are curettage and filling with cancellous bone and radiotherapy (when surgery is contraindicated). Preoperative arterial embolization (ideally 2 weeks before surgery) helps control intraoperative bleeding during surgery for giant pelvic pseudotumors. Peripheral nerve injuries, which are rare, almost always occur due to compression of hematomas in the vicinity. In most cases, they usually resolve with hematological treatment only. If such treatment fails, surgery would be indicated.

A rare case of cryptococcal infection of talus with pathological fracture that healed with medical management

Skeletal involvement occurs in 5% to 10% of reported cases of disseminated cryptococcal infection. We are reporting a very rare presentation of cryptococcal infection of the talus with pathological fracture, which healed with medical management. Our patient had pain and swelling around the ankle associated with fever. Radiologically, he had a lytic lesion of the talus with fracture of the talar neck. Biopsy and cultures revealed cryptococcal infection. He was treated with surgical debridement combined with antifungal therapy, and the fracture healed well by 5 months. At the end of the 1-year follow-up, he had painless ankle movement and there was no evidence of recurrence. He was able to walk without support or limp, and he could wear normal footwear.
