Abstract:
A 64-year-old man complained of pain in the left side of his neck and chest. Subsequently, the symptoms were aggravated and paralyzes of the left upper and lower extremities appeared. With the diagnosis of polyneuritis, steroid pulse therapy was started, but he showed no improvement in symptoms. An FDG-PET/CT scan was performed. FDG accumulated in the lumbar spinal canal and along the left brachial and bilateral lumbosacral plexuses, suggesting involvement by malignant tumors. These findings appeared to be consistent with the clinical and cytologic diagnosis of malignant lymphoma. After systemic chemotherapy, all the above-mentioned accumulations disappeared and he achieved a complete remission.
