Recently, percutaneous drainage has been more popular because it is relatively simple, convenient, and less invasive. fter warfarin overuse, a 71-year-old male patient visited the emergency room with femoral neuropathy caused by a left iliacus muscle hematoma measuring approximately 110 64 mm, 75 60 mm in size on coronal and sagittal computed tomography angiograhy. Without trauma, weakness of the left hip flexor and left knee extensor was noted with strength of 2/5 (poor) each. Immediate medical treatment using vitamin K and fresh frozen plasma was started and percutaneous drainage was performed. Two days after visiting the emergency room, neurological symptoms were improved and non-operative treatment was continued. Twenty four days after being hospitalized, the size of the hematoma was reduced to approximately 75 45 mm, 62 40 mm in size. pproximately three months after hospitalization, most of the hematoma was absorbed. fter one year, mild atrphy of quadriceps and mild diffuse pain were noted, however, no other symptoms were observed.
