Title: Ultrasound and Contrast-enhanced Ultrasound Patterns of Primary Psoas Major Muscle Diffuse Large B-cell Lymphoma: A Case Report
Abstract: Diffuse large B-cell lymphoma involving skeletal muscle is rare and accounts for less than 0.1%, most frequently affecting the lower extremities. A 63-year-old man complained of a persistent fever, accompanied by waist discomfort. Computed tomography and ultrasound detected an ill-defined solid mass in the right psoas major muscle. Contrast-enhanced ultrasound showed that peripheral inhomogeneous hyper-enhancement with nonenhancing central necrotic area was seen in the mass. Then, ultrasound-guided biopsy was performed and revealed diffuse large B-cell lymphoma. This is the first case report demonstrated the primary psoas major muscle lymphoma and analyzed the ultrasound and contrast-enhanced ultrasound features of the tumor.
