Multiple intracranial arachnoid cysts.

A 26-year-old-man presented with intermittent headache for the last two years. The patient had no other medical history such as infection, subarachnoid hemorrhage, trauma or malignancies affecting central nervous system. A cranial CT and MR were performed. Cranial imaging revealed multiple arachnoid cysts located in right temporal fossa (Galassi type 2), left temporal fossa extending to the convexity (Galassi type 3), prepontine cistern extending to the cerebellopontine angle cistern and laterally to the left cerebellar hemisphere, cerebellar interhemispheric fissure (Fig. A). The arachnoid cyst was located left to the temporal fossa and extended to the convexity and caused a moderate shift in central cranial structures. The arachnoid cysts had the same signal intensity as cerebrospinal fluid in FLAIR and other conventional sequences (Fig. B). On diffusion MR, lesions had no restricted diffusion (Fig. C). No concomitant brain abnormality was identified. Neurological examination findings were not compatible with intracranial stasis. The patient underwent cyst fenestration operation and the diagnosis was also confirmed histopathologically. After the operation the amount of headache episodes and shift of central cranial structures decreased

Radiologic imaging procedures during pregnancy: Safety and risks [Gebelikte radyolojik görüntüleme yöntemleri]

Many women become ill while pregnant and require acute medical care, including radiologic examinations with ionizing radiation. In this review; radiologic imaging methods can be used during pregnancy, it's safety and risks to the fetus are discussed. There have been no reports of documented adverse fetal effects for diagnostic ultrasound and magnetic resonance imaging. It is not recommended the diagnostic x-ray procedures should not be performed during pregnancy unless the information to be obtained by other means especially ultrasound, although, the x-ray exposure from a single diagnostic procedure doesn't result in harmful fetal effects

Nasal cavity and paranasal sinus bony variations: a computed tomographic study

WOS: 000090021300003PubMed ID: 11072655Variations of the nasal cavity are very important for the otolaryngologist in functional endoscopic sinus surgery. To provide data on bony variations of this region, we performed high resolution computed tomography images of paranasal sinuses on 82 adult patients without sinus pathology and on 90 adult patients with sinus disease. We observed paradoxical curvature of the middle concha in 11 (12.22%) sinus patients and 6 (7.31%) in non-sinus patients. Concha bullosa was observed in 26 sinus patients (28.88%) and 22 (26.83%) in non-sinus patients, deviated nasal septum in 20 (22.22%) sinus and 10 (12%) non-sinus, Haller's cell in 5 (5.55%) sinus and in 3 (3.65%) non-sinus, agger nasi cell in 7 (7.77%) sinus and 4 (4.88%) non-sinus patients. Pneumatisation of cristae galli was observed in 8 (8.88%) sinus and 2 (2.44%) non-sinus, of the anterior clinoid process in 5 (5.55%) sinus and 1 (1.22%) non-sinus patients, pneumatisation of the nasal septum in 7 (7.77%) and of the pterygoid recess in 12 (13.33%) sinus patients We did not find any correlation between age intervals and paranasal sinus variations, and also no statistically significant difference was observed between males and females. These data provide very important information to guide the otolaryngologist and/or radiologist in the evaluation of patients with coronal CT which guides functional endoscopic sinus surgery

Diaphragmatic crus lipoma: a case report

WOS: 000077851800008PubMed ID: 9890188Diaphragmatic crus lipoma is a very rare entity. In this case report, smooth, rounded masses of diaphragmatic lipoma, incidentally observed in a 37-year-old female on routine abdominal computed tomographic scanning is presented.

Prediction of late complication of femoral neck fractures by MRI [COCUK FEMUR BOYUN KIRIKLARINDA GEC DONEM KOMPLIKASYONLARININ ERKEN TANISINDA MAGNETIK REZONANS GORUNTULEMENIN YERI]

Femoral neck fractures in children are uncommon injuries and are often associated with excessive incidence of complications, such as avascular necrosis. Precise and early close reduction, surgical fixation, long immobilization, delayed weight bearing and late follow up are mandatory to decrease the amount and severity of complication. Between 1990 and 1992, seven cases with this injury were treated at the Department of Orthopaedics and Traumatology of Ege University Medical School. A prospective study was undertaken to determine the value of MRI in predicting avascular necrosis of the femoral head following femoral neck fractures. MRI was carried out in 7 patients 1 year after first operation. In the MRI Stage I avascular necrosis. All the patients were followed up for at least 1 year. The results indicate that postoperative MRI is useful in children to predict avascular necrosis of femoral head. MRI has been found to be accurate in predicting this complication following femoral neck fractures. It is agreed that MRI have great importance in preparing the medicolegal reports and establishing the prediction of late complication in the follow up of femoral neck fractures of the children
