Abstract:
A soft-tissue aneurysmal bone cyst located on the lateral aspect of the left thigh of a 12-year-old girl is described. Conventional radiography of the thigh was normal. Sonography showed a hypoechoic mass with a feeding vessel and intralesional vascularity. On MRI, it was of predominantly soft-tissue signal intensity with intense enhancement following administration of i.v. contrast medium. Histopathological examination diagnosed the lesion as a soft-tissue aneurysmal bone cyst. This is the fourth paediatric case of this very rare benign tumour.
