over half of all reported traumatic brain injuries are the result of a motor vehicle accident. other then the direct head impact itself, the sheer forces of the accident can cause the brain also to collide against the internal bone of the skull. in fact, when a moving head comes to a quick stop, the brain continues in its movement, striking the interior of the skull. this can cause bruising of ...

traumatic brain injury is a common entity. however cerebral infarction in infants is a rare entity while the diagnosis of this pathology in the pediatric population is usually difficult. the mild head trauma is rarely accompanied by intracranial injury and even less, with cerebral infarction. we herein report the first case of cerebral infarction after a mild brain trauma in a 2-year-old latin-...

Abstract Background Sarcopenia is increasingly recognised to impact the quality of life and patient outcomes. The relationship with brain frailty unknown. Objectives Assess if muscle mass at C3 correlates L3 on routine trauma imaging. for associations between muscle-mass, brain-frailty, Clinical Frailty Scale (CFS) Method Routine trauma-series CT scans were retrospectively analysed patients age...

Meningioma is the second most common brain tumor. The extent of peritumoral brain edema (PTBE) is one of the important prognostic factors in patients with meningioma.A 55-year-old female patient suffering from a progressive severe headache and mild left hemiparesis was referred to the Department of Neurosurgery, Rasool Akram Hospital (Tehran, Iran). The preoperative imaging revealed a 2×2 cm so...

Brain tumors are the most common solid tumors in childhood. Glioblastoma multiform (GBM) is the second most common primary brain tumor in adults. It usually affects the cerebral hemispheres of adults at the 6th or 7th decade of life. In comparison to adult population, GBM is rare in pediatrics and accounts for approximately 3% of all pediatric brain tumors. Pediatric glioblastoma was defined as...

an interesting case of rare multiple hydatid of parotid, brain and kidney is reported. she is a 35-year-old married woman first referred because of a swelling in the parotid region and later for neurological manifestions. on general physical examination, an abdominal mass was felt in the right hypochondrium. these multiple space-occupying 'lesions in the brain, kidney and parotid proved to be h...

As brain size usually increases with body size it has been assumed that the two are tightly constrained and evolutionary studies have therefore often been based on relative brain size (i.e. brain size proportional to body size) rather than absolute brain size. The process of domestication offers an excellent opportunity to disentangle the linkage between body and brain mass due to the extreme s...

Introduction: Investigation of radiation interaction with living organs has always been a thrust area in medical and radiation physics. The investigated results are being used in medical physics for developing improved and sensitive techniques and minimizing radiation exposure. In this study, mass attenuation coefficients of different human organs and biological materials such as adipose, blood...
