A 33-year-old woman first noticed numbness in the both lower extremities and the numbness gradually extended up to the thorax. Magnetic resonance (MR) imaging demonstrated a mass with moderate and heterogeneous enhancement and peritumoural intramedullary cysts in the spinal cord at the T-1 to T-3 levels. The tumour was explored partially and intra-operative pathological examination demonstrated the so-called "two-cell pattern" typical of germinoma. The margin of the tumour was not clear. Histological examination showed germinoma with strong c-kit protein expression on the tumour cell surface. Chemotherapy and radiation therapy were given following surgery. Her neurological deficits were improved but not resolved.
