Extraosseous aneurysmal cyst. A case presentation

We present a case of a soft tissue aneurysmal cyst [STAC] in a 13 year old girl. The lesion was detected in the left paraspinal lumbar region extending from the level of transverse process of 2[nd] lumbar vertebra to the transverse process of 4[th] lumbar vertebra. The lesion was investigated by plain X- ray, ultrasound, bone scan, computed tomography [CT], and magnetic resonance imaging [MRI]. Pathological examination has been done preoperatively by fine needle aspiration cytology [FNAC], and histologically after surgical excision
