[An autopsied patient with palatal tremor and fatal bilateral vocal cord abduction paralysis associated with bilateral cerebellar dentate nucleus infarction].

A 74-year-old male patient developed multiple infarcts of the brainstem and cerebellum, followed 14 months later by palatal tremor and bilateral vocal cord abduction paralysis, resulting in death due to type 2 respiratory failure. Pathologic analysis revealed old infarcts extending from the bilateral cerebellar cortices to the dentate nucleus, being more extensive on the right side, accompanied by Wallerian degeneration involving the left red nucleus, right central tegmentum tract, and inferior cerebellar peduncle, followed by pseudohypertrophy of the bilateral inferior olivary nuclei. These lesions, involving the Guillain-Mollaret triangle, may have been responsible for the palatal tremor.

Long Spinal Cord Lesions Caused by Venous Congestive Myelopathy Associated with Intravascular Large B-cell Lymphoma.

Intravascular large B-cell lymphoma (IVLBCL) is a subtype of B-cell lymphoma, characterized by lymphoma cell proliferation within small blood vessels. We herein describe a rare case with long spinal cord lesions caused by venous congestive myelopathy associated with IVLBCL. An 81-year-old man presented with paraplegia of the lower limbs and sensory disturbances.

Duplication and deletion upstream of in autosomal dominant adult-onset leukodystrophy.

Objective: To characterize the genetic and clinical features of patients with autosomal dominant adult-onset demyelinating leukodystrophy (ADLD) carrying duplication and deletion upstream of lamin B1 ().

Methods: Ninety-three patients with adult-onset leukoencephalopathy of unknown etiology were genetically analyzed for copy numbers of and its upstream genes. We examined expression by reverse transcription-qPCR using total RNA extracted from peripheral leukocytes.

Globular glial tauopathy Type II: Clinicopathological study of two autopsy cases.

Globular glial tauopathies (GGTs) are four-repeat tauopathies characterized by the presence of two types of tau-positive globular glial inclusions (GGIs): globular oligodendrocytic and astrocytic inclusions (GOIs and GAIs). GGTs are classified into three different neuropathological subtypes: Types I, II and III. We report two patients with GGTs - a 76-year-old woman and a 70-year-old man - in whom the disease duration was 5 and 6 years, respectively.

Identification and functional characterization of novel mutations including frameshift mutation in exon 4 of CSF1R in patients with adult-onset leukoencephalopathy with axonal spheroids and pigmented glia.

Objective: Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is caused by mutations in CSF1R. Pathogenic mutations in exons 12-22 including coding sequence of the tyrosine kinase domain (TKD) of CSF1R were previously identified. We aimed to identify CSF1R mutations in patients who were clinically suspected of having ALSP and to determine the pathogenicity of novel CSF1R variants.

Partial loss of function of colony-stimulating factor 1 receptor in a patient with white matter abnormalities.

Background And Purpose: Mutations in colony-stimulating factor 1 receptor (CSF1R) cause adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP). Patients with ALSP can be misdiagnosed as having acute ischemic stroke due to hyperintensity lesions on diffusion-weighted magnetic resonance imaging. Mutant CSF1R proteins identified in ALSP show a complete loss of autophosphorylation of CSF1R.

A novel frameshift GRN mutation results in frontotemporal lobar degeneration with a distinct clinical phenotype in two siblings: case report and literature review.

Background: Progranulin gene (GRN) mutations are major causes of frontotemporal lobar degeneration. To date, 68 pathogenic GRN mutations have been identified. However, very few of these mutations have been reported in Asians.

Cognitive dysfunction and symptoms of movement disorders in adult-onset leukoencephalopathy with axonal spheroids and pigmented glia.

Adult-onset leukoencephalopathies are clinically and genetically heterogeneous disorders that affect predominantly the cerebral white matter of the central nervous system. Clinical and neuroimaging-based approaches have been developed to improve diagnostic processes for adult-onset leukoencephalopathies. However, the differential diagnosis is often challenging.

Fibromyalgia in a Patient with Cushing's Disease Accompanied by Central Hypothyroidism.

A 39-year-old woman with a 3-year history of a rounded face developed widespread myalgia. Detailed examinations revealed no disorders that could explain the pain other than concomitant Cushing's disease and central hypothyroidism. Both the hypercortisolemia and hypothyroidism completely resolved after the patient underwent surgery to treat Cushing's disease, but she continued to experience unresolved myalgia and met the diagnostic criteria for fibromyalgia.

Histopathological analysis of spontaneous large necrosis of adrenal pheochromocytoma manifested as acute attacks of alternating hypertension and hypotension: a case report.

Background: Pheochromocytomas are rare catecholamine-producing neuroendocrine tumors. Hypertension secondary to pheochromocytoma is often paroxysmal, and patients occasionally present with sudden attacks of alternating hypertension and hypotension. Spontaneous, extensive necrosis within the tumor that is associated with catecholamine crisis is an infrequent complication of adrenal pheochromocytoma, but its pathogenesis remains unclear.

Diagnostic Value of Brain Calcifications in Adult-Onset Leukoencephalopathy with Axonal Spheroids and Pigmented Glia.

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia is a rare neurodegenerative disease resulting from mutations in the colony stimulating factor 1 receptor gene. Accurate diagnosis can be difficult because the associated clinical and MR imaging findings are nonspecific. We present 9 cases with intracranial calcifications distributed in 2 brain regions: the frontal white matter adjacent to the anterior horns of the lateral ventricles and the parietal subcortical white matter.

Abnormal ghrelin secretion contributes to gastrointestinal symptoms in multiple system atrophy patients.

Patients with multiple system atrophy (MSA) often have evidence of compromised gastrointestinal motility. Ghrelin is a gut hormone that influences gastrointestinal motility in humans. The aim of this study was to determine whether ghrelin secretion is affected in MSA patients, and to investigate the relation between ghrelin secretion and gastrointestinal symptoms.
