A-51-years old presented with three months history of shoulder pain followed by frequent occipital headaches associated with gait imbalance and vomiting. PET scan, done after shadowing was seen in left middle and lower lung on chest X-ray, revealed left lung mass metastatic to the infracarinal lymph nodes, left adrenal gland, along with diffuse bone metastasis. MRI brain showed a lobulated mass in the fourth ventricle. The patient underwent sub-occipital craniotomy for resection of the fourth ventricle lesion. A mucoid soft mass was resected, and histopathological examination showed adenocarcinoma with intestinal differentiation. CT guided biopsy of the lung lesion was inconclusive, upper and lower GI endoscopies were negative for malignancy. To the best of our knowledge, this is the first case reported in literature of lung adenocarcinoma with intestinal differentiation with metastasis to the fourth ventricle.
