Epithelioid hemangioendothelioma (EHE) is one of the rarest vascular tumor found in brain. In pediatric group patients, proportion EHE only 0.02% all brain neoplasms, and therefore oncogenesis causes are currently not well understood. Intracranial localization extremely rare, nevertheless, this type neoplasm should be included differential diagnostic series when multiple small intracerebral mas...
A 63-year-old man was admitted to our hospital with a complaint of right lateroabdominal pain. He was diagnosed with metastatic colon cancer, and then developed multiple brain embolic infarctions 7 days after admission. Transesophageal echocardiography showed that mobile, echo-dense masses were attached to the anterior and posterior mitral valve leaflet. Furthermore, there was a thrombus in the...
Background: Neck mass is one of the most common clinical findings in all age groups. Differential diagnosis of masses includes a range of pathologies from congenital to infectious or neoplasm. Understanding the risk factors of neck masses can help us to assess them properly. The purpose of this study is to obtain the epidemiological and clinical features of different neck masses in Kerman, Iran...
Restricted water diffusion has been used to distinguish pyogenic abscess from other rim-enhancing brain masses; however diffusion-weighted imaging of cerebral infection before capsule formation has rarely been described. We report a case of fungal cerebritis in which water diffusion was more restricted than that of normal contralateral brain and the measured diffusion coefficient was in the ran...
A five-year-old male Boerboel presented for examination, collapsed for an unknown period of time. On clinical examination, multifocal subcutaneous masses and enlarged prescapular lymph nodes as well as neurological deficits that suggested a multifocal neurological syndrome were found. Fine needle aspirates of the prescapular lymph nodes revealed cells suggestive of osteosarcoma. Radiographs sho...
tubercle bacilli infect about one third of the world's population and over the past decade resurgence of tuberculosis has been a major health threat mainly due to increasing frequencies of immunosuppressive states and drug-resistant organisms. although tuberculosis is essentially a lung disease, intracranial elements become involved in 5-10% of cases either as meningitis or tumour-like masses (...
BACKGROUND Alzheimer's disease (AD) is the most common neurodegenerative disorder, manifesting clinical symptoms of cognitive impairment and dementia. The vast majority of cases are late onset AD (LOAD), which are genetically heterogeneous and occur sporadically. The neuropathological changes of LOAD can be reproduced by supplementing a rabbit's diet with 2% cholesterol for 12 weeks. METHODS ...
In a retrospective study, type, origin and relative frequency of pelvic masses during 3 years period in shariati hospital were studied. Ovarian mass was the most common pelvic mass with relative frequency of 88% including neoplastic 58% and non neoplastic 30%. Corpus luteom cyst was the most common cyst in non neoplastic group and serous cystadenoma was the most common in neoplastic group. The ...
Intracranial bleeding is an important cause of brain masses and edema. To study the pathophysiology of intracerebral hemorrhage, we produced experimental hemorrhages in 53 rats and characterized the lesion by histology, brain water content, and behavior. Adult rats had 2 microliters saline containing 0.5 unit bacterial collagenase infused into the left caudate nucleus. Histologically, erythrocy...
