We report the sonographic features of an intracystic papillary carcinoma of the breast presenting as recurrent hemorrhagic cysts following trauma. A 56-year-old woman presented with palpable breast masses after a traumatic event; sonography showed multiple, well-defined, hemorrhagic cysts. Hemorrhagic fluid was evacuated by fine needle aspiration with no residual lesions. Cytology was negative ...

INTRODUCTION Recurrent hemorrhagic pericardial effusion in children with no identifiable cause is a rare presentation. CASE PRESENTATION We report the case of a 4-year-old Indian girl who presented with recurrent hemorrhagic pericardial effusion. Diffuse lymphangiomatosis was suspected when associated pulmonary involvement, soft tissue mediastinal mass, and lytic bone lesions were found. Peri...

The effect of anticoagulation on lesions caused by cerebral emboli of different types was studied in 57 dogs. The resultant arterial and parenchymal lesions were assessed by pathologic and angiographic studies. Embolization with emboli that caused little or no inflammatory response in the artery (12 dogs) was not associated with hemorrhagic infarcts or with subdural or subarachnoid hemorrhage; ...

Brain injury in the premature infant is an extremely important problem, in part because of the large absolute number of infants affected yearly. The 2 principal brain lesions that underlie the neurological manifestations subsequently observed in premature infants are periventricular hemorrhagic infarction and periventricular leukomalacia. The emphases of this article are the neuropathological f...

MYOCARDIAL LESIONS are produced soon after the onset of hemorrhagic shock in dogs (1, 2). It has been our contention that important factors in the pathogenesis of these lesions are the decreased filling of the ventricle (3) coupled with the increased endogenous secretion of catecholamines after hemorrhage. This leads to a situation in which the ventricle is beating strongly, with an incompletel...

PURPOSE To investigate the decrease in signal intensity on T1 - weighted MR images of some hemorrhagic intracranial lesions after administration of contrast material. METHODS Postprocessing digital image subtraction was performed in 16 MR studies (13 patients) of lesions that showed hyperintensity on noncontrast T1-weighted images. Repetition time and echo time were identical for all precontr...

Acute Hemorrhagic Edema of Infancy is an infrequent leukocytoclastic vasculitis which occurs almost exclusively in children between 4 months and 2 years of age. It is clinically characterized by the triad fever, purpuric lesions on the face, auricular pinna and extremities, and edema. Although the cutaneous findings are dramatic and of rapid onset, the prognosis is favorable, with spontaneous r...

OBJECTIVE To evaluate the radiological and clinical findings of congenital cystic neuroblastomas as compared with those of the cystic presentation of neonatal adrenal hemorrhage. MATERIALS AND METHODS We analyzed the US (n = 52), CT (n = 24), and MR (n = 4) images as well as the medical records of 28 patients harboring congenital cystic neuroblastomas (n = 16) and neonatal adrenal hemorrhagic...

Acute hemorrhagic edema of infancy is a cutaneous leukocytoclastic vasculitis, clinically characterized by the acute development of peripheral edema and targetoid purpuric lesions on the face and extremities. The clinical picture has a violent onset with a short benign course followed by spontaneous complete recovery. We describe a five-month-old boy with acute hemorrhagic edema, in whom the di...

subulura brumpti infection was observed in japanese quails and caused heavy production loss up to 10%. gross lesions were confined to caecum of the affected birds. pathological changes suggestive of acute cecal hemorrhagic enteritis were recorded. closer observation of the cecal loop revealed wavy movement with thousands of tiny worms. based on morphometry, the worms were identified as s. brump...
