We describe a patient with paraneoplastic neurologic syndrome confirmed on postmortem examination. This 42-year-old man was admitted due to general fatigue, emaciation and acute-onset disorientation. Neurological examination revealed disorientation, moderate cognitive impairment, cerebellar ataxia, bilateral limitations and nystagmus in all directions during external ocular movement, swallowing disorder, bilateral Babinski sign, sensory disturbance in the distal parts of all extremities, and Romberg's sign.

A right-handed Japanese man with no consanguinity exhibited personality changes, speech disorder and abnormal behaviors, such as stereotypical, running-away, environment-dependent, and going-my-way behaviors, since the age of 49 years. At age 52 years, neuropsychological examination revealed frontal lobe dysfunctions, mild memory impairment, and transcortical sensory aphasia. MRI showed symmetrical severe atrophy of the anterior part of the temporal and frontal lobes.

Recurrence of spontaneous cervical internal carotid artery (ICA) dissection is not rare (1%/year) but bilateral recurrence affecting the same cervical ICA is rare, especially after a 12-year-interval. A 41-year-old man exhibited left hemiparesis and angiography revealed tapered stenosis of his right cervical ICA. Within 2 days, his hemiparesis improved.

A 50-year-old previously healthy woman presented with symptoms of subarachnoid hemorrhage. Initial cerebral angiography did not determine the site of the hemorrhage but repeat angiography disclosed an aneurysm-like image, probably in the medial posterior choroidal artery (PChA). Selective angiography performed using a microcatheter technique clearly revealed two medial PChAs arising from the ambient segment of the posterior cerebral artery.

We describe a patient presenting with trochlear nerve palsy and segmental sensory disturbance due to circumscribed mesencephalic hemorrhage. A 36-year-old man with no past illness visited our hospital complaining of sudden onset of diplopia, dysesthesia of the left face and upper extremity, and acuphenes of the left ear. Neurological examination revealed left trochlear nerve palsy and segmental sensory disturbance of the left side almost above T11 level.

Background: Recently, acute human T-lymphotropic virus type 1-associated myelopathy (HAM) was reported clinically without pathologic information. We report an autopsy case of acute HAM.

Objective: To report the case of a 52-year-old man with acute-onset gait disturbance followed by rapidly progressive paraplegia, who died 9 months later.

We reported a 35-year-old male patient with acute type adult T cell leukemia(ATL) and human T-lymphotropic virus type I associated myelopathy. He presented meningitis and polyradiculoneuropathy and improved with steroid treatment. He presented headache and sensory ataxia and these symptoms responded to steroid treatment.

We studied clinical symptomatology and somatosensory evoked potentials(SEP) of 7 pure sensory stroke patients due to pontine lesions. Clinical symptoms were examined by modality(pinprick, touch, vibration and joint position sense), intensity and distribution of the sensory disturbance. SEP were recorded by the median nerve stimulation in the upper extremities, and the posterior tibial nerve stimulation in the lower extremities.

We are reporting an autopsy case of so-called "acute multiple sclerosis" that was difficult to differentiate from a brain tumor on MRI findings. This case was a 69-year-old man, whose initial symptoms consisted of headache and unsteadiness in walking. Neurological findings included mild ataxia of the left upper extremity and positive Romberg sign.

A rare case of cerebellopontine angle epithelial cyst presenting as hemifacial spasm is reported. The patient was a 35-year-old man with right hemifacial spasm of 2 months duration. A preoperative CT scan showed a well-demarcated low density area in the right cerebellopontine angle.

We conducted a comparative analysis of the autopsy findings in a case of Marchiafava-Bignami disease with the X-ray computed tomography (CT) and magnetic resonance imaging (MRI) findings obtained while the patient was alive. Histologically, massive deposits of hemosiderin were demonstrated in the astrocytes and macrophages located in the walls of the callosal cystic lesion, suggesting that the transient increase in density during the subacute stage observed on X-ray CT is secondary to significant hemorrhage.

Anterior choroidal artery (Ach A) syndrome is widely known to be composed of a triad of hemiparesis, hemisensory loss and homonymous hemianopia. The authors report a case of Ach A-territory infarction after a direct operation for internal carotid artery aneurysms, which presented transcortical sensory aphasia in association with the characteristic triad. The literature and several previously reported cases with dominant and nondominant cerebral hemisphere signs in AcH A infarction are reviewed.

The patient was a right-handed 59-year-old female technician who was admitted to our hospital with a complaint of memory loss. Clinical examination revealed pure anterograde amnesia regarding episodic memory, while semantic and procedural memory was intact. Radiological procedures (CT scan and MRI) revealed a tumor of the septum pellucidum, which localized from the lower part of the corpus callosum to the anterior parts of the bilateral fornices.

A fifty-nine-year-old alcoholic man with severe hypoglycemic encephalopathy was examined using sequential CT scans of the brain (CT). Twenty-seven hours after the attack, which resulted in a comatose state, CT disclosed multiple low density areas throughout the cerebral cortex which resembled multiple cortical infarctions. CT obtained four days after the ictus demonstrated more prominent low density areas in the cerebral cortex, diffuse cerebral edema and partial cortical enhancement after administration of contrast medium.

A case of diffuse idiopathic skeletal hyperostosis causing dysphasia was reported. A 62 year-old man was admitted to our hospital complaining of nuchal pain and dysphagia. Roentgenograms of the cervical spine demonstrated a "flowing" ossification anterior to three contiguous vertebral bodies, C 4-6.

Sensory disturbance in the unilateral hand and ipsilateral mouth region, the cheiro-oral syndrome, may be due to cortical, thalamic, or brainstem lesions. We report five patients with this syndrome due to infarction at the border of the posterior limb of the internal capsule and the corona radiata. The sensory fibers from the mouth area and hand probably travel to the cortical sensory areas in close proximity after leaving the posterior ventral thalamic nucleus.

In order to study the secretion of gonadotropins in clinically non-functioning pituitary adenomas, 83 cases were investigated by immunohistochemistry. Expression of one or more of gonadotropin subunits (alpha-subunit, follicle-stimulating hormone (FSH) beta, luteinizing hormone (LH) beta) was found in 38 (45.8%) of all adenomas studied.

Paroxysmal cerebellar ataxia (PCA) is a specific disease which exhibits spasmodic cerebellar ataxia but rarely shows abnormal neurological findings in the intermission. Verger first described an isolated case. Subsequent reports of the disease included mostly cases with autosomal dominant inheritance, but the reports have been limited to about 20 families.

We have observed two cases with marked reading and writing deficits, in which speech and oral comprehension were generally intact. Detailed symptomatological study was performed on these cases, and the lesions were examined organically (X-ray computed tomography [X-ray CT], magnetic resonance imaging [MRI] and functionally (positron emission tomography [PET]. In addition to the marked reading and writing deficits, mild naming and memory disorders were found.

A case is reported of a 71-year-old female with cervical myelopathy caused by calcified nodules in the cervical ligamentum flavum and improved by en bloc laminectomy. The calcified nodules were formed by the deposition of two crystals, hydroxyapatite (HAP) and calcium pyrophosphate dihydrate (CPPD). Light microscopy, scanning electron microscopy, energy dispersive X-ray microanalysis and X-ray diffraction study disclosed that the larger nodule located on the right was composed mainly of HAP in the central part and CPPD in the circumference.

A case of spontaneous cervical epidural hematoma associated with long-term cervical spondylosis is presented. A 69-year-old man was admitted with a 3-day history of sudden onset of severe neck pain radiating to both upper extremities followed by impossibility in standing. Neurological examination on admission revealed paralysis below C7, total anesthesia below the T4 level and urinary incontinence.
