We present the MR findings in three neurologically symptomatic newborns after vacuum extraction delivery. The lesions included subdural hematomas, one tentorial hematoma, and one intracerebellar hemorrhage. One patient had hydrocephalus that required shunting. We propose that the visualized abnormalities are probably the result of vertical stress leading to laceration of bridging veins, venous ...

Description is given of changes in blood coagulability found in diseases of the rabbit, including malignant tumor, spontaneous infections, non-bacterial diseases and lesions, and hemorrhagic states specifically induced. The changes involved variously the time of onset of blood coagulation, clot formation rate and the rate and extent of clot retraction.

MR images of granulomatous amebic encephalitis caused by leptomyxid amebae in an HIV-infected patient showed both heterogeneous and ring-enhancing hemorrhagic lesions. The brain was diffusely involved, including the brain stem, deep gray matter nuclei, and corticomedullary junction regions of all lobes.

A 44-year-old woman with prolonged coma and hypotension following drug overdosage developed bilateral hemorrhagic infarcts in the dorsolateral brainstem. The regional distribution of these paired lesions corresponds to the area of confluence of penetrating arteries in the brainstem. It is suggested that under exceptional circumstances brainstem arterial end-zones may be vulnerable to anoxic-isc...

A 19-year-old woman was referred to our emergency department for massive vaginal hemorrhage following an attempted clandestine abortion by intravaginal instillation of potassium permanganate crystals. Primigravida, she 7 weeks pregnant and had no particular pathological history. Upon admission, in hemorrhagic shock with blood pressure at 7/3 mmHg tachycardia 152 bpm. Pelvic examination revealed...

BACKGROUND AND PURPOSE A cavernous angioma is a developmental vascular malformation with a high risk of hemorrhage. The purpose of this work was to retrospectively determine whether an MR sign of T1 hyperintense perilesional signal intensity is useful for the differentiation of cavernous angioma from other hemorrhagic cerebral masses. MATERIALS AND METHODS The institutional review board appro...

myelogenous leukemia, type M5, was admitted for Ara-C and idarubicin induction chemotherapy. On treatment day 5, febrile neutropenia developed with a leukocyte count less than 0.1 × 109/L and a platelet count of 8 × 109/L. There was a painless reddish-purple lesion, 2 to 3 cm in dimension, on the right lower abdominal wall, diagnosed as a hemorrhagic blister from trauma. Over the next 2 days su...

OBJECTIVE Optimal platelet inhibition is an important therapeutic adjunct in patients with carotid artery stenosis undergoing carotid artery stenting (CAS). Clopidogrel resistance is associated with increased periprocedural thromboembolic complications from neurovascular stent placement procedures. The addition of cilostazol to dual antiplatelet therapy (DAT) has been reported to reduce platele...

background: linear endoscopic ultrasonography (eus) is a proven modality for the diagnosis and treatment of different gastrointestinal lesions. the aim of this study was to describe the role of eus-fna in the evaluation of pancreatic and submucosal lesions. materials and methods: over a 1-year period, in a prospective descriptive study, patients referred to naft hospital, underwent linear eus. ...

The term 'vascular dementia' (VaD) corresponds to a clinicoradiological syndrome that can be defined with more or less restriction. VaD can result from: (1) cortical or subcortical ischemic lesions related to the occlusion of large vessels, (2) lacunar infarcts with or without white-matter lesions at the subcortical level related to small-vessel diseases, (3) ischemic lesions related to hypoper...
