The examination of links between a high degree of encephalisation (i.e., a large brain mass relative to body size) and the capacity of wildlife to inhabit anthropogenic habitats has formed the basis of several recent studies, although typically they have not uncovered any relationship. It, however, remains unclear whether encephalisation is directly related to a species’ capacity to develop tol...

Objective(s):   Recently, applications of MnO2 nanoparticles and microparticles in industry, pharmacology, and medicine have considerably expanded. Mn distribution and clearance from brain and spinal cord tissue compared with muscle tissue of rats after single subcutaneous injection of nanoparticles and microparticle of MnO2. Pain sensory threshold of rat was evaluated as neurologic consequence...

A benign chondroblastoma of the temporal bone in an 8-year-old boy is reported. Head CT showed an expansile mass with calcifications in the center. The tumor appeared as a well-lobulated, hypointense intraosseous mass on T1-weighted brain MR; it was isointense to brain parenchyma on intermediate-weighted images and enhanced homogenously with gadolinium.

INTRODUCTION Neuroglial heterotopia, heterotopic brain tissue, or differentiated neural tissue outside the cranial vault is uncommon, and these anomalies most commonly occur in the nasal cavity. CASE PRESENTATION We report a case of rare pure cystic heterotopic brain tissue in a two-month-old Caucasian baby girl that presented as a large cystic neck mass and was confused with a cystic hygroma...

How do cell number and size determine brain size? Here, we show that, in the order Rodentia, increased size of the cerebral cortex, cerebellum, and remaining areas across six species is achieved through greater numbers of neurons of larger size, and much greater numbers of nonneuronal cells of roughly invariant size, such that the ratio between total neuronal and nonneuronal mass remains consta...

In this study, 22 patients (15-75 years old) were selected and transferred to CT scan for tumor ablation. For ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. Then, laser probe inserted through the needle and laser energy delivered. Although we ...

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...

Primary thymic adenocarcinoma is a very rare malignancy of the anterior mediastinum with no standardized treatment. A 36-year-old male patient presented with hoarseness over the past 3 months. A chest computed tomography (CT) scan showed an infiltrative mass to the proximal vessels and aortic arch in left upper mediastinum (4.1×3.1×5.4 cm). Brain magnetic resonance imaging (MRI) showed focal le...

The midsagittal surface area of the corpus callosum was determined by computer-assisted morphometry in juvenile and adult members of 13 species of the cetacean family Delphinidae. In 57 brains, absolute callosal areas ranged from 104 to 829 mm2. When compared to other mammal groups possessing a corpus callosum, callosal area in dolphins was smaller in relation to brain mass with a ratio range (...

introduction: 99mtc-mibi has been proposed for use as an imaging agent for various tumors, including breast cancer, lung cancer, lymphomas, melanomas and brain neoplastic lesions. brain tumors are very common and radiotherapy being major part of treatment following surgery. after radiotherapy, deteriorating clinical status can be due to either radiation necrosis or recurrent tumor. computed tom...
