Abstract

Advanced gastric cancer with skeletal muscle metastasis is a rare occurrence. Here, we report a rare case of gastric carcinoma with psoas muscle metastasis. This patient had advanced gastric carcinoma and complained of inability to extend the left hip joint due to pain. Because magnetic resonance imaging (MRI) revealed an iliopsoas mass showing heterogeneous signal intensity with fluid collection and enhancement around the mass, we speculated that the mass was an intramuscular metastatic tumor from primary gastric carcinoma as well as an intramuscular abscess. Histopathologically, the patient had a metastasis from primary gastric adenocarcinoma. Therefore, the patient was treated with radiotherapy and subsequent chemotherapy.
