A Rare Clinical Report of Intramuscular Hemangioma of the Middle Scalene Muscle.

Intramuscular hemangioma (IMH) is an uncommon benign vascular lesion, which develops in skeletal muscles and it accounts for <1% of all hemangiomas. The accurate diagnosis is often difficult because the clinical and radiological findings are not specific. The gold standard treatment of IMH is surgical resection. We present a rare clinical report of IMH of the middle scalene muscle that was treated successfully with preoparative embolization and surgical excision.

Localized Chronic Form of Langerhans Cell Histiocytosis in the Femur of a 16-Year-Old Male Successfully Treated with Radiofrequency Ablation.

Only three cases of patients suffering from a localized chronic form of Langerhans cell histiocytosis (LCH) successfully treated with radiofrequency ablation (RFA) have been published so far. This is the first case report of a patient with a localized chronic form of LCH of the femur, which was successfully treated with percutaneous image-guided RFA, and who was evaluated pre-RFA and followed up post-RFA for a period of 48 months, in order to validate the safety and efficacy of this method and to obtain imaging studies depicting the actual in situ changes taking place post-RFA. RFA was proved to be a safe and efficient method when treating patients with a localized chronic form of LCH.
