We report the magnetic resonance imaging (MRI) and clinico-histologic characterization of dorsally exophytic brain stem gliomas (DEBSGs). Between 1983 and 1991, 12 of 51 patients evaluated for the diagnosis of brain stem glioma were found to have DEBSGs emanating from the pons, pontomedullary junction or medulla. Eleven of the 12 patients had classic juvenile pilocytic astrocytomas. Unlike most other brain stem tumors, these patients were young (median 38 months, range 17-75), had a relatively long duration of symptoms (median 7 months, range 2-24) and displayed signs of increased intracranial pressure with limited cranial nerve paresis, absence of pyramidal tract findings, and near normal brain stem auditory-evoked potentials. MRI characteristically showed sharply demarcated lesions with decreased signal intensity on T1, and increased intensity on T2 sequences. Except for cystic areas, these tumors showed bright, uniform enhancement after gadolinium-DTPA. In all patients, 50-100% of the tumor volume could be resected. Three of 10 patients who received no immediate postoperative treatment eventually demonstrated disease progression, and 2 patients with subtotal resections who were treated with radiation and/or chemotherapy postoperatively remain disease-free for extended periods of time. The only death occurred in the 1 patient treated with chemotherapy who died of secondary leukemia. The overall and progression-free survival of these patients at 2 years is 100 and 67% as compared to 18 and 21%, respectively, for other concomitantly treated nonexophytic brain stem gliomas.2+ the ability to achieve significant degrees of resection.

We report a 45-year-old man with monocytosis and right hemiparesis. The patient suffered from an acute myocardial infarction from which he recovered completely when he was 42 years old. One year prior to his death, he was found to have increase in monocyte count (35.5% of leukocytes) in peripheral blood and splenomegaly; he was admitted to the hematology service of our hospital. He was diagnosed as having chronic myelomonocytic leukemia after bone marrow examination. He was treated with radiation therapy with improvement in splenomegaly. In May of 1995, he had fever, anemia, and thrombocytopenia for which he needed daily blood transfusion. In November of 1995, he had an onset of weakness in his right hand, and neurologic consultation was asked for in November 27, 1995. Neurologic examination revealed a chronically ill japanese man in no acute distress. He was alert and not demented. Higher cerebral functions were intact. Cranial nerve examination revealed right facial paresis of the central type. Motor-wise, he was right hemiparetic. Generalized muscle wasting was noted apparently due to the chronic debilitating disease. Deep tendon reflexes were within normal range in the right upper extremity, but were diminished in other areas. Sensation was intact, and no meningeal signs were noted. Pertinent laboratory findings were as follows: Hb 8 g/dl, RBC 238 x 10(4)/microliter, WBC 2,900/microliter (band 1.0%, seg 18.5%, lym 28.0%, mono 44.0%, Baso 2.5%), Plt 13 x 10(4)/microliter, PT 16.6"/10.9", APTT 44.7"/35.0". CSF contained 87 mg/dl of protein, 155 mg/dl of glucose and 2 mononuclear cells/microliter. Bone marrow was slightly hypercellular with mild increase in blast forms. No chromosome abnormality was found. CT and MRI revealed a large mass in the left fronto-parietal region and the meninges showed marked thickening with enhancement after gadolinium-DTPA in MRI. The patient was treated with glycerol and steroid, but the subsequent course was complicated by a seizure, agitation, and pneumonia. He died from respiratory failure on January 13, 1996. The patient was discussed in a neurologic CPC and the chief discussant arrived at the conclusion that the patient had chronic myelomonocytic leukemia with infiltration of leukemic cells into meninges and the parenchyme of the cerebrum. Thickening of the dura was thought to be in part a reaction to the subdural hematoma as well as to leukemic cells along the meninges. Postmortem examination revealed hypercellular bone marrow with increase in monocytic cells (more than 20%). The lungs showed pneumonia with scattered old tuberculous lesions. The heart showed an old myocardial infarction in the posterior wall of the left ventricle. The brain showed an old chronic subdural hematoma in the left fronto-temporal region and a cystic mass lesion in the left frontoparietal region. The mass was hypercellular and most of them were monocytes. The dura mater showed reactive thickening without leukemic cell infiltration. It was concluded that this patient had chronic myelomonocytic leukemia with a formation of leukemic mass in the brain. Pathologists thought that the mass was a hematogenous spread. It is rare for chronic myelomonocytic leukemia to form a mass lesion in the brain.

We reported a fourteen years old male with subdural empyema followed by consecutive magnetic resonance imaging (MRI) examination. He was admitted to our hospital, complaining incomplete paresis of the left upper extremities, headache and high fever. The first MRI T2-weighted image at admission revealed an abnormal high intensity in the right frontal subdural space, indicating an abscess. Antibiotics therapy and a burr hole operation were effective and he made a remarkable recovery. One month later, the third MRI T2-weighted image showed an abnormal high intensity in the deep white matter of the right frontal lobe, which had not been detected in the subsequent MRI after the operation. On the other hand, the meningeal enhancement on the second Gd-DTPA enhanced MRI was more thickened than the previous meningeal enhancement. This abnormal high intensity on MRI had disappeared two month later, when the meningeal enhancement had grown thin. These data suggested the meningeal enhancement was relative to the transient high intensity which was considered to represent brain edema. We concluded that careful observation and serial MRI examination might be necessary in patient with subdural empyema even after disappearance of all symptoms.

We reported a 50-year-old man with an overlap syndrome of dermatomyositis and SLE, whose magnetic resonance image of the brain showed a rapidly increasing large tumor-like focal lesion unequally enhanced by Gd-DTPA in the left frontal lobe. Its pathological finding by the brain biopsy was fibrinoid necrosis, inflammatory cell aggregation around blood vessels and many myelin-laden macrophages with central necrosis. Although many cases of blood vessel injury are reported in CNS lupus, in this case the brain lesion partly took reversible course and neural symptoms such as paresis were slight and the lesion well responded to steroid. Moreover we considered that the measurement of serum anti-ribosomal P and CSF antineuronal antibodies are useful to diagnose cases as CNS lupus.

A 10-year-old, female poodle was presented with left paresis and vestibular signs, following left enophthalmus and atrophy of the cheek. Magnetic resonance imaging revealed a mass along the base of the brain and extending from the left cerebellopontine angle to the sella turcica. The mass showed isointensity on the T1-weighted image and T2-weighted image, and was enhanced by contrast medium (Gd-DTPA). Although occipital craniotomy was carried out and the mass removed, the dog died without recovering from the anesthesia. The tumor was diagnosed pathologically as fibroblastic meningioma.

Anterior spinal artery syndrome is rare in children, especially in neonates. We present a girl with hydrops fetalis and hypothyroidism who developed flaccid paresis of both arms in the neonatal period (around day 25). MRI of the spine performed on day 52 revealed atrophic changes at C5-Th1 without Gd-DTPA-induced enhancement. Nerve conduction studies were also helpful in the diagnosis;in the upper limbs, motor potential was not elicited, while sensory nerve conduction velocity was normal. These clinical and laboratory findings suggested an atypical case of anterior spinal artery syndrome.

A 75-year-old woman was admitted to our hospital because of sudden onset of paresis in her left arm and face. She had untreated hypertension and hyperlipidemia. When she came back home after playing with children in the park, she felt weakness in her left hand. On admission, physical examination revealed that her blood pressure was very high (200/102 mmHg). Only slight weakness in her left arm and left facial palsy were recognized neurologically. An electroencephalogram showed normal findings. Brain CT and MRI revealed a venous angioma near the right central sulcus. Gadolinium-DTPA enhanced MRI showed a group of small radiating veins (so called "the caput medusae sign") connected to the venous angioma. The remaining symptoms decreased with the normalization of blood pressure. It is suggested the intracranial motor tracts of the face and arm in the precentral gyrus are adjacent to the location of this venous angioma. The dilation of venous angioma due to high blood pressure was thought to cause the paresis of face and arm in this patient.
