PURPOSE To determine whether there are statistically significant differences in cerebral blood volume (CBV) and cerebral blood flow (CBF) of brain tumors of different histopathologic types including primary and secondary benign and malignant lesions. To determine whether these measurements relate to tumor grade. MATERIALS AND METHODS Forty-five patients(More)
Although conventional magnetic resonance imaging (MRI) findings of glutaric aciduria type 1 (GA-1) have been well established, diffusion weighted MR imaging (DWI) and proton MR spectroscopy (MRS) findings are limited. We report widespread restricted diffusion in the white matter and increased diffusion in bilateral putamen in a case of GA-1. The MRS showed(More)
Thirty-three structural curves of 25 patients with adolescent idiopathic scoliosis were evaluated using computed tomography (CT) scans and plain radiography. The average Cobb angle on standing radiographs was 55.72 degrees and was observed to be corrected spontaneously to 39.42 degrees while the patients were in supine position (29.78% correction). Average(More)
Eosinophilic granuloma (EG), a benign bone lesion, represents a focal form of histiocytosis X. Here, the authors report a case of an extremely rare presentation of a solitary EG of the skull. A 9-year-old boy presented with headache and vomiting for 3 days. His examination was unremarkable except for a tender mass in his left occipital region. Radiological(More)
Spinal epidural extramedullary haematopoiesis is very rare in thalassaemia. A 27-year-old man with thalassaemia intermedia presented with symptoms and signs of spinal cord compression. MRI showed a thoracic spinal epidural mass, representing extramedullary haematopoietic tissue, compressing the spinal cord. Following radiotherapy, serial MRI revealed(More)
Endoscopic transsphenoidal surgery is emerging as a minimally invasive and maximally effective procedure for pituitary adenomas. In this report we analyzed the complications in 624 procedures of endonasal transsphenoidal endoscopic surgery in the treatment of 570 patients with pituitary adenomas. The leading author (MB) operated pituitary adenomas via pure(More)
Dysembryoplastic neuroepithelial tumors (DNTs) were first described by Daumas-Duport et al. in 1988 as a typically cortical tumor affecting young patients with long-standing, drug-resistant epilepsy. We reviewed the medical records of 29 patients with DNT between 1994 and 2007 at Hacettepe University Children’s Hospital retrospectively; age at the time of(More)
A case of rhombencephalosynapsis, a very rare disorder characterized by agenesis or hypogenesis of the cerebellar vermis and fusion of the cerebellar hemispheres, is reported with magnetic resonance imaging features. Radiographs showed anomalies in both hands; namely phalangeal hypoplasia and occult polydactyly in the right hand and syndactyly in the left,(More)
Imaging features of infants who suffered from brain damage as a result of neonatal hypoglycemia were shown to have similar patterns, and to affect the parietal and occipital lobes most severely. Long term follow up regarding clinical outcome of patients with neonatal hypoglycemia and this pattern of damage are limited. We reviewed the medical records of 24(More)
Several radiological methods have been utilized to assess velopharyngeal function. The more recent imaging technique, magnetic resonance imaging (MRI), which has a number of advantages over radiographic and computed tomographic imaging, has been used rarely for evaluating velopharyngeal insufficiency. In this study, 5 normal volunteers and 10 patients with(More)
