Ileo-psoas muscle metastasis from pulmonary carcinoma
Keywords:Pulmonary carcinoma, Psoas muscle, Metastasis, Adenocarcinoma
Metastatic disease to muscle is rare and may be misdiagnosed when it is the presenting symptom, particularly in the absence of a known primary tumor. Skeletal muscle metastasis as a mode of presentation of primary lung cancer is an unusual phenomenon. Here, we report a case of ileo-psoas muscle metastasis from lung cancer as the initial clinical manifestation in a 58 year-old male with a personal history of heavy smoking. Excisional biopsy of the mass in the ileo-psoas muscle revealed metastatic adenocarcinoma. Computed tomography scan of the chest for a primary search was done and found to be pulmonary carcinoma.
