A semiautomated computer analysis was developed to estimate fluid volumes in each hemicranium from computed tomography scans. The method was used to estimate total ventricular and sulcal fluid in 123 normal subjects aged 23-88 years. A wide range of normal values was found. The trend was for the estimated ventricular and sulcal fluid volumes to remain relatively constant until age 60 and then t...

We report a retrospective study to determine the cost-effectiveness of cranial computed tomography in patients with headache without neurological finding. Five hundred ninety-two neurologically normal patients were examined between 1990 and 1993 for the complaint of headache. Examination results were reevaluated from written report and image archive systems. Results were divided into three grou...

We report a Japanese man who presented with multiple cranial nerve palsies with hepatitis B virus-related multiple hepatocellular carcinoma (HCC). He presented with right III, IV, VI, IX, X, and XII cranial nerve palsies. Metastases involving the clivus and the right occipital bone from HCC were diagnosed by the findings of magnetic resonance imaging of the head, cerebral angiography, and 2-deo...

Brain foreign bodies and penetrating missile injuries of the brain are familiar topics for Iranian physicians, especially after Iran and Iraq war. But it’s not easily plausible that there is a couple of sewing needles in the cranium of a patient who has not any history of head trauma or penetrating injury. The patient was a 42-year-old man who admitted in neurology ward of Mottahari Hospital in...

Real-time cranial sonography via the anterior fontanelle was used serially over a 3- and 6-week period, respectively, to evaluate two infants who developed multicystic encephalomalacia secondary to Citrobacter neonatal meningitis. Sonographic findings included heterogeneous parenchymal echogenicity, gyral prominence, periventricular hypoechoic areas from which cystic spaces evolved, and develop...

The present study was aimed at proposing a systematic evaluation of cranial computed tomography, identifying the main aspects to be analyzed in order to facilitate the decision making process regarding diagnosis and management in emergency settings. The present descriptive study comprised a literature review at the following databases: Access Medicine and Access Emergency Medicine (McGraw- Hill...

conclusion there is still excessive unjustified concern of pte in less trained physicians leading to excessive diagnostic work-up. loyalty to the existing guideline for management of suspected pte in educational hospitals and supervision of attending physicians could prevent overuse of ctpa. results during a 6-month period, 82 patients who underwent ctpa were included. the prevalence of pte was...

background: proper rotation of components in total knee arthroplasty (tka) will largely affect the postoperative outcome. ethnical variation may affect rotational profile. we aimed to evaluate distal femur rotation in iranian population using transepicondylar axes.   methods : from a total of 450 knee ct scans and via consecutive sampling, 150 qualified subjects with normal lower extremities al...
