Hospital Course:

The patient is a 64-year-old Native American man who was admitted to the hospital due to worsening lower back pain, numbness, and tingling radiating down both legs. On admission, the patient also reported gradually increasing weakness in both legs for 3 days that led to an inability to walk. The patient had a medical history significant for hepatitis C, for many years, which led to liver cirrhosis. The patient also had a history of a previously repaired umbilical hernia. The patient's family history included breast cancer (sister) and lung cancer (mother). The patient was a former heroin abuser, but never consumed alcohol. The patient worked as a manager in the laundry department in a hospital, and family members denied any exposure to asbestos. An ultrasound of the liver 1 year prior to the current presentation reported coarse echotexture suggestive of underlying cirrhosis. 

Physical examination revealed marked weakness of the patient's lower extremities and swelling over the T9 area of his spine. On neurological examination, the patient was alert and awake, oriented to time, his name, and his location; and his cranial nerves were grossly intact. While no gait disturbance was observed, severe cord compression was noted due to a pathologic fracture at T11. Magnetic resonance imaging of his thoracic and lumbar spine revealed numerous metastatic lesions, and a large right liver mass and multiple lesions were also seen in MRI scans of the chest, abdomen, and pelvis.

Surgical spinal cord decompression and stabilization/fusion of his spine was performed, and pathology results of an intervertebral disc and the T9 vertebral body showed metastatic carcinoma favoring HCC. Tumor cells were positive for Hep Par-1 and glypican-3 and negative for CK7, CK20, TTF-1, inhibin, OCT3/4, PSA, PSAP, RCC, and PAX8. Subsequently, the patient was treated with radiation to the T11 spine lesion and was scheduled to begin radioembolization with yttrium-90.

Unfortunately, the patient's condition deteriorated, and he died 2 months after diagnosis. No autopsy was performed.
