Case Reports
A Case of Intestinal Obstruction Due to Reassembly after Endoscopic Crushing of a Bezoar.
An 87-year-old woman visited her primary-care doctor because of nausea and epigastric pain. Esophagogastroduodenoscopy (EGD) revealed a giant bezoar in her stomach. She was referred to our hospital after carbonated beverage dissolution proved ineffective and underwent endoscopic mechanical crushing. ⋯ Later, however, the crushed fragments reassembled in the duodenal bulb and caused intestinal obstruction. The patient underwent emergency EGD for crushing once more, and all of the fragments were extracted from the body. This case highlights the need for bezoars to be removed from the body after crushing in order to avoid reassembly.

The pathophysiology of idiopathic intracranial hypertension (IIH) and idiopathic normal-pressure hydrocephalus (iNPH) differs in terms of cerebrospinal fluid (CSF) pressure and imaging-related characteristics. A 51-year-old man presented with optic nerve papillary edema, visual disturbance, bilateral abducens nerve palsy, and a wide-based gait. Imaging showed characteristic findings of IIH and disproportionately enlarged subarachnoid space hydrocephalus (DESH) - characteristic of iNPH. ⋯ IIH with iNPH-like imaging features (DESH) was diagnosed, and ventriculoperitoneal shunt surgery was performed. Postoperatively, the visual acuity and visual field improved. This report also describes the distinct and overlapping pathophysiological mechanisms of IIH and iNPH.

We encountered a 37-year-old Japanese man with KIF1A-associated neurological disorder (KAND) who exhibited motor developmental delay, intellectual disability, and slowly progressive cerebellar ataxia, hypotonia, and optic neuropathy. Pyramidal tract signs were evident late in this case. At 30 years old, the patient developed a neurogenic bladder. ⋯ L278P) of KIF1A. Serial neuroradiological studies revealed atrophy of the cerebellum at an early age, and cerebral hemisphere atrophy progressed slowly over a 22-year observation period. Our study suggests that the primary etiology of KAND may be acquired, long-standing neurodegeneration rather than congenital hypoplasia.

Case Reports
Hyperthyroidism-induced Cerebral Venous Thrombosis Presenting as Chronic Isolated Intracranial Hypertension.
A 38-year-old woman with untreated Graves' disease was admitted to our hospital because of headache and diplopia for 3 months. A neuro-ophthalmic examination showed bilateral papilledema and abducens nerve paralysis. The cerebrospinal fluid pressure was extremely high. ⋯ The patient recovered after propylthiouracil and anticoagulation therapy. We herein report a rare case of cerebral venous thrombosis with hyperthyroidism presenting as chronic isolated intracranial hypertension. Hyperthyroidism can induce a hypercoagulable state and lead to venous thromboembolism.

Gaucher disease (GD) causes the accumulation of glucocerebrosides in various organs, resulting in hepatosplenomegaly, anemia, decreased platelet counts, and bone disorders. Glucosylsphingosine accumulates in the brain and causes central nervous system (CNS) disorders. ⋯ We administered SRT to GD types I and III patients and found it effective. Malignancy is a late complication of GD, but this is the first report of Barrett adenocarcinoma.
