Carcinoid tumor is regarded as a tumor with low grade malignancy, mostly originating from the gastrointestinal tract with little danger of metastasis. The authors encountered a very rare case of bronchial carcinoid tumor that had multiple metastasis to the intracranial space. The characteristics of radiological and hormonal examinations of this tumor are reported and discussed. The patient was a 73-year-old woman who gradually developed unsteadiness in walking and somnolence in daytime one month prior to admission. Those symptoms were aggravated and she began to vomit. On admission, neurological examination showed slight ataxia of left upper and lower extremities and dominant truncal ataxia. Chemical and hormonal examinations of blood and urine showed, gastrin was 230 pg/ml (37-172), ACTH was 67 pg/ml (< 60), serotonin was 565 ng/ml (53-200), and urinary 5-HIAA was 9.9 mg/day (0.8-4.8). Tumor markers (CEA, AFP, HGG, NSE) were all negative. Radiological examinations (chest X-P, CT scan) of her lung demonstrated a 3 x 3 cm tumor mass adjacent to the hilum of the left lower lobe. CT-scan of the head demonstrated cystic tumor in the vermis of the cerebellum (3 x 3 cm), the right posterior parietal lobe and the right temporal lobe. The wall of each tumor was enhanced by contrast medium. T1 weighted MRI demonstrated the walls of cystic tumors as iso intensity and the contents as low and high intensity with niveau formation. Little edema was recognized around the tumors. The wall of each cystic tumor was enhanced by Gd-DTPA.(ABSTRACT TRUNCATED AT 250 WORDS)

Neuromyelitis optica (NMO), or Devic's syndrome, is an autoimmune central nervous system demyelinating disorder primarily affecting the spinal cord and the optic nerves. It is characterized by the presence of NMO antibodies, alongside clinical and radiological findings. NMO and NMO-spectrum disorders (NMO-SD) have been reported in autoimmune disorders, and are infrequently described as a paraneoplastic syndrome with cancers of lung, breast, and carcinoid tumors of the thyroid. We report a patient who presented with severe vomiting, blurring of vision, vertigo, diplopia, left hemiparesis and hemisensory loss and ataxia. She was found to have a longitudinally-extensive demyelinating lesion extending from the medulla to the upper cervical spinal cord on MRI. Her gastric endoscopy revealed carcinoid tumor of the stomach, and classic paraneoplastic antibodies in the serum were negative. She had extremely high serum gastrin level and high titer of NMO IgG autoantibody. The patient made an excellent recovery with tumor resection and immunotherapy, with both clinical and radiological improvement. On rare instances, NMO or NMO-SD may present as a paraneoplastic neurological syndrome associated with carcinoid tumor of the stomach.
