METHODS To demonstrate hemispheric asymmetry, standard CT scans of 30 schizophrenic patients (14 males, 16 females) were compared with 39 (13 male, 26 female) control subjects at Eskisehir Osmangazi University, Eskisehir, Turkey in 2005. Brain volumes were investigated by using a cheap, simple stereologic method, namely, Cavalieri. RESULTS In patients with schizophrenia, we found that as age increases, right and left hemisphere volumes decrease. However, in the control group there was no relationship found between age and hemisphere volumes. In the control group, the left hemisphere was significantly bigger in males compared to females. There was a significant difference in both right and left hemisphere volumes between the control group and the schizophrenic group. In the schizophrenic group, a significant difference ...

The most common radiological findings are thrombus in the dural sinus or cortical veins, paranchimal hemorrhagic infarctions, focal edema with or without hemorrhage. However, in a review of the literature, only a few cases of CVST were associated with subdural effusion. We report superior sagital sinus and cortical veins thrombosis with bilateral subdural effusion in a 17 year-old girl with leukemia.

CT-myelography was taken of 38 patients with low back pain andi or radicular pain complaints, most of whom were suffering disc herniation. Measurements of cross-sectional area of spinal cana\, dural sac, disc herniation beyond interspace (where appropriate) and ligamentum flavum were taken in 43 levels. These were levels L4-S and LS-Si lumbar disc hernia was assumed prediagnostically every case. The spinal reserve capacity area was calculated by substracting the rest from the spinal canal area. The ratio between spinal canal and dural sac area as well as that between spinal canal area and spinal reserve capacity were separately calculated for each level. These ratios were then examined for possible correlation with the neurological condition of the patients. Statistical analyses show the neurological condi...

Anatomical abnormalities can be acquired or congenital and most of them are located in the head and neck region. Congenital defects include inner ear abnormalities, patent cochlear aqueduct, patent Hyrtlʼs fissure, abnormal developed facial canal and dehiscence at the lateral end of the internal auditory canal. In this case report, recurrent meningitis due to nonimplanted ear in a cochlear implant patient with bilateral congenital inner ear abnormality was discussed with surgical and radiological findings.

However, since CT scans are often preferred in the evaluation of primary tumours of these patients, information about lymphatic metastases may also available in these patients. Therefore, ultrasound is not routinely employed in the evaluation of these patients. However, elastography technique, a recent development in ultrasound technology, could make use of ultrasonography in these patients even more widespread, even though it is still not widely used today. The aim of this study was to evaluate the role of sonographic elastography in the diagnosis of lymph node metastasis of head and neck cancer. Twenty-three patients diagnosed with head and neck cancer and scheduled for surgical treatment including neck dissection were included in the study. All patients underwent neck examination by palpation, ultrasound elastography and computerized tomography with contrast...

There are a few studies showing hyperintensity of basal ganglia associated with manganese deposition in hemodialysis (HD) patients. The present study aimed to investigate the intensity changes as markers of manganese deposition in the basal ganglia and to demonstrate their association with blood manganese levels using ICP/MS technique in HD, peritoneal dialysis (PD), and renal transplant patients. The study included 20 HD, 20 PD, 20 renal transplant patients, and 20 healthy controls. Blood manganese levels were obtained, and cranial magnetic resonance images were evaluated for basal ganglia hyperintensity. Blood manganese levels were similar across all study groups (p = 0.308), whereas symmetric basal ganglia hyperintensity indicating manganese deposition was detected only in HD patients (p = < 0.001). There was a significant relationship between manganese deposition and...

Brains of patients with dementia show physical differences according to disease types and phases.... more Brains of patients with dementia show physical differences according to disease types and phases. Physical characteristics of brains such as cortical thickness and volumes of some parts have a significant effect on determining the type of the disease. Magnetic resonance imaging devices create visual files which contain patient information appropriate to the medical imaging standards. Using image processing techniques, numerical expressions of patients' brains can be extracted via these files. By means of using these numeric values with classification methods, patients can be classified. In this study, samples having three diseases: Alzheimer's disease, vascular dementia and fron to temporal dementia are used. After extracting cortical surface area, thickness and volume features, samples are classified successfully with artificial neural networks due to feature selection.

Twenty one patients with congenital aural atresia (14 male, 7 female) aged between 1-30 years were evaluated with high resolution computed tomography of the temporal bone. A Toshiba TCT-600 scanner was used in 11 cases, and a Xvision/GX scanner was used in 10 cases. Sections 1 mm thick were obtained in axial and coronal projections using high bone detail algorithms. Sagittal reformations were also made when necessary. Forty-two ears in 21 patients with congenital aural atresia were studied. These included 8 patients with high bilateral and 13 with unilateral congenital aural atresia in which 8 patients had right sided and 5 patients had left sided atresia. Stenosis of the external auditory canal was found in 11 ears, complete atresia was found in 13 ears, incomplete atresia was found in 1 ear. There was varied ossicular deformity in 18 ears. Anomalies of the stapes and oval window were found in 6 ears. An anteriorly located mastoid segment of the facial nerve canal was identified in 11 ears. An inferiorly located tympanic segment of the facial nerve canal was identified in 2 ears, and 3 ears had an abnormal posterior orientation of the mandibular condyles. Only 2 patients had associated inner ear deformity. High resolution computed tomography is an effective method for the evaluation of the anomalies of the external, middle and inner ear in patients with congenital aural atresia and for planning the surgical treatment.

In membranous obstruction of the inferior vena cava, the hepatic segment of the inferior vena cava is obstructed by a fibromuscular membrane or replaced by a cordlike fibrous tissue. We report the computed tomography and ultrasound findings of a 45 year old patient with membranous obstruction of the inferior vena cava and hepatocellular carcinoma.

Median nerves at the carpal tunnel were evaluated by using gray-scale and power Doppler ultrasonography and by using accepted and new criteria in 42 patients with CTS (62 wrists) confirmed by electromyogram and 33 control subjects. We evaluated the cross-sectional area of the nerve just proximal to the tunnel inlet (CSAa), and at mid level (CSAb). We then calculated the percentage area increase of CSAb, and area difference (CSAb-CSAa). We measured two dimensions of the nerve at the distal level to calculate the flattening ratio. The power Doppler ultrasonography was used to assess the number of vessels, which proceeded to give a score according to the vessel number, and lastly evaluated the statistical significance by comparing the means of patients with control subjects by the Student t test for independent samples. Sensitivities and specificities were determine...

A case report and review of the literature are presented. Two-thirds of reported cases occur in healthy individuals, although chronic disease states enhance susceptibility to this injury in a significantly younger patient population. Routine laboratory screening for rheumatologic, endocrine, and renal disease is therefore advocated for all presenting patients. Diagnosis is clinical; review of the literature documents the efficacy of early repair followed by appropriate immobilization and aggressive physical therapy.

Here, we report the first Turkish case of vCJD. A 47-year-old man, who has never lived outside of Turkey and had had no transfusion, was admitted to the University Hospital with speech disorder, cognitive decline and ataxia following depression, irritability, and personality change. The immunoassay of the 14-3-3 protein in the cerebrospinal fluid was negative. Brain magnetic resonance imaging revealed high-signal lesions involving the bilateral caudate and lentiform nucleus on T 2-and diffusion-weighted imaging. The patient developed akinetic mutism 10 months after disease onset. The clinical presentation and neuroimaging findings were compatible with the vCJD cases reported since 1996 and met the World Health Organization's case definition for probable vCJD.

Although the etiology of pneumocele is not entirely known, several causative factors have been suggested including trauma, surgery, tumor and infection. We report here a case of post-traumatic pneumocele of the frontal sinus following a head trauma. pneumocele of the frontal sinus is a rare disorder that can accompany a facial deformity. A pneumocele is characterized by the pathological expansion of the aerated sinus lined by normal mucosa. Pneumoceles most commonly affect the frontal sinus, followed in frequency by the sphenoid, ethmoid and maxillary sinuses (1). The etiology of a pneumocele is still unclear, but it might occur after head trauma, nasal polyposis, sinus surgery, chronic sinusitis and the formation of a tumor. We report a case of pneumocele of the frontal sinus and suggest that the pneumocele occurred after trauma to the head in a patient. CASE REPORT A 46-year-old man was admitted to our hospital with a 4-week history of headache and a growing mass on the left forehead. The patient had a history of severe head trauma due to a traffic accident that occurred 21 years prior. Over the intervening years, the patient had noticed a slowly growing mass on the left forehead. A physical examination demonstrated the presence of a hard mass, about 6 6 cm in size, on the left forehead. There were no abnormal findings after both a neurological and ophthalmological examination. Cranial multi-detector computed tomography (MDCT) was performed using a 64-MDCT unit (Aquilion 64; Toshiba, Tokyo, Japan) with a 0.5mm-section width, a rotation time of 500 ms, tube voltage of 120 kV and tube current of 180 mA. The reconstructed images were processed, and multiplanar reformatted and three-dimensional (3D) volume-rendering (VR) images were processed on a separate workstation (Vitrea 2; Vital Images, Plymouth, MN). These images showed an abnormally expanded left frontal sinus with concurrent thinning of the bony wall (Figs. 1A C). There was no sign of frontal bone fracture, despite the previous cranial trauma. Coronal reformatted MDCT images showed that the left frontal recess was obliterated with a soft tissue density. The other sinuses were normal. The 3D CT VR image showed an abnormal protrusion of the forehead due to a pneumocele of the frontal sinus (Fig. 1D). Surgical treatment was offered as an option for correcting the deformity but was refused by the patient.

Coronal reformatted MDCT images showed that the left frontal recess was obliterated with a soft tissue density. The other sinuses were normal. The 3D CT VR image showed an abnormal protrusion of the forehead due to a pneumocele of the frontal sinus (Fig. 1D). Surgical treatment was offered as an option for correcting the deformity but was refused by the patient.
