A Buttock Soft Tissue Tumor and Sciatica: Another Clinical Utility of Ultrasound-Guided Diagnosis Block.

Abstract

Abstract Sciatica is a symptom rather than a specific diagnosis. It usually consists in a radiating leg pain from the buttock toward the knee, ankle, foot and toes. Pain could be associated with neurological deficit, such as muscle weakness and reflex deficit. The prevalence of sciatica in spine pathology is highly variable with values ranging from 1.6% to 43%. Between 70%-90% of the cases of herniated disc with nerve-root compression caused sciatica. Other causes are lumbar canal or foraminal stenosis, tumours or cysts. We present a case evaluated in our Pain Unit with left-sided sciatic pain after an intense voluntary movement two months ago. He was previously pharmacologically treated for a non-specific low back pain with pseudo-sciatica. One week later buttock soft tissues sarcoma was diagnosed. He deceased two weeks after the diagnosis
