Intramedullary spinal cord metastases (ISCM) are a clinically rare, although devastating, complication of disseminated cancer. These lesions have been reported to originate from many types of solid tumors, although primary lung carcinoma, particularly small cell, is the most common etiology. These metastases, which can occur anywhere along the spinal cord, often represent the end-stage of the disease process with limited survival outcomes.

Patients with ISCM may develop a variety of neurological deficits with treatment goals aimed at palliation. Different modalities of treatment have been found to preserve or restore ambulation and neurological function. The options for therapeutic intervention include surgical, chemotherapeutic, and radiation therapy. We describe a case of ISCM in a patient with disseminated small cell lung cancer with magnetic resonance imaging that illustrates a complete tumor response to radiation therapy
