Marchiafava–Bignami disease (MBD) is a very rare disorder characterized by demyelination and necrosis of the corpus callosum. A 53-year-old male was transported to emergency room with impaired consciousness. On his arrival, he quite emaciated.

Acute hemorrhagic edema of infancy is a distinctive, cutaneous small vessel leukocytoclastic vasculitis of young children with dramatic characteristic skin findings. It is characterized by low- grade fever, erythematous edema, and purpuric lesions mainly on the face and extremities. Visceral involvement is uncommon, and spontaneous recovery usually occurs within one to three weeks without seque...

BACKGROUND Hereditary hemorrhagic telangiectasia is characterized by angiodysplastic lesions. So far, knowledge is limited on the vascular architecture and rate of occult manifestation of telangiectases. Contact endoscopy has not been used for this task before. METHODS Eleven patients with hereditary hemorrhagic telangiectasia were examined with contact endoscopy to identify occult telangiect...

Severe hemorrhagic enterocolitis was observed in a Siberian tiger (Panthera tigris altaica) and a lion (Panthera leo). Both animals developed acute depression, anorexia, and bloody diarrhea several days before death. Small and large intestines were diffusely congested, edematous, necrotic, and filled with hemorrhagic fluid, and mesenteric lymph nodes were enlarged and congested. Pure and abunda...

Southeast of Iran is an endemic area for Malaria and Crimean-Congo hemorrhagic fever (CCHF). In 1999, we faced with an outbreak of CCHF in Sistan and Baluchistan Province, in the border of Pakistan and Afghanistan. The most cases of Malaria in Iran are also reported from this area. This article presents a 17-year- old woman who admitted to our hospital because of acute fever, headache, epistaxi...

A 27-year-old Japanese man presented with erythema nodosum and consciousness opacity of four days in duration. He had panuveitis and fever. A cerebrospinal fluid (CSF) analysis revealed 100/mm pleocytosis (polynuclear cells, 87%) and the elevation of interleukin-6 (5,630 pg/mL). Brain MRI demonstrated multiple hemorrhagic cerebral cortical lesions with gadolinium enhancement (Picture A, DWI; C,...

Background and Purpose. In pyogenic brain abscess, hemorrhage in the walls is considered exceptional. Recently, hemorrhagic changes in the walls of pyogenic abscess have been demonstrated on susceptibility weighted imaging with 3T MRI. Here, we report hemorrhagic changes in the walls of pyogenic brain abscess on susceptibility weighted imaging with 1.5T MRI. Method. MRI of brain was done using ...

Cerebral amyloid angiopathy is increasingly recognized as a major cause of hemorrhagic stroke in the elderly as well as an important contributor to the growing challenge of vascular cognitive impairment, even in cerebral amyloid angiopathy patients without hemorrhagic stroke. Among the advances highlighted in this update are: (1) the importance of sulcal bleeding events in early recurrent hemor...

Background Follicular dendritic cell (FDC) sarcoma is an extremely rare neoplasm, which has only been reported once in the literature with an intracranial occurrence. Neither hemorrhagic presentation of an intracranial instance of FDC sarcoma nor its rapid recurrence has yet been published in the literature. Case Description We report the case of a 61-year-old female who presented with confus...

INTRODUCTION Hemorrhagic retinal macrocysts are extremely rare retinal lesions that can be mistaken for malignancy with subsequent enucleation. Such a case was diagnosed, by a retina specialist based on ultrasonography, as a choroidal melanoma with exudative retinal detachment and the patient was advised to have brachytherapy. CASE PRESENTATION A 15-year-old Caucasian boy suffered sudden visu...
