Large cell carcinoma of the lung metastatic to nuchal muscle.
Clinically apparent hematogenous skeletal muscle metastases from lung cancer are extremely rare. We present a 72-year-old man with a large cell lung carcinoma metastatic to nuchal muscle. Cervical computed tomography (CT) and magnetic resonance imaging (MRI) revealed the presence of a well-defined mass in the left splenius capitis muscle. A percutaneous needle biopsy was performed to establish a diagnosis. Localized skeletal muscle swelling may rarely prove to be metastases in patients with lung cancer, but should be investigated in the case of muscle swelling.
