Frontochoanal polyp: case report.

Choanal polyps are solitary benign growths that can cause unilateral nasal obstruction. A frontochoanal polyp originates from the frontal sinus and extends to the nasopharynx. These lesions are rare and are usually diagnosed by endoscopic examination and computed tomography.

Small bowel obstructions secondary to bezoars.

Background: We aimed to present our experience on computed tomography (CT) findings of small bowel obstruction due to bezoar impaction.

Methods: CT scans of seven patients (3 males, 4 females, age range; 30-93 years) who were diagnosed as small bowel obstruction due to bezoars were reviewed.

Results: In each patient, an intraluminal mass with a mottled gas pattern on CT enabled specific preoperative diagnosis of bezoars, and postoperative changes such as anastomotic lines and afferent-efferent loops.

Case report: seizures in a child caused by a large venous angioma.

Cerebral venous angioma is a congenital anomaly of the medullary vein, the vessel that drains into the transparenchymal venous stem. This lesion is also referred to as a developmental venous anomaly. A few reports in the literature have documented developmental venous anomaly-related epilepsy, neurologic deficits, and intracranial hemorrhage.

The role of standing flexion-extension radiographs for spondylolisthesis following single level disk surgery.

Objectives: Spondylolisthesis is the forward displacement of a lumbar vertebra relative to the adjacent vertebra, occurs as result degeneration or surgery and is a special type of lumbar instability. There is no consensus about which radiologic modality or findings truly reflect the lumbar instability and the exact incidence after single level disk surgery is unknown.

Methods: In this prospective study, we have included 90 patients who were operated by the same surgeon with single level disk herniation.

Accuracy of sonography for detecting renal stone: comparison with CT.

Purpose: To determine the diagnostic accuracy values of sonography in the detection of renal stones using noncontrast CT as the gold standard. In addition, we correlated the accuracy of sonography with stone size, the kidney affected (right versus left), and body mass index (BMI).

Methods: Fifty patients underwent 2 separate sonographic examinations performed by 2 radiologists.

Combined off-pump coronary artery bypass grafting and aorto-bicarotid bypass.

A 63-year-old man with severe coronary artery disease and occlusion of aortic arch branches presented with dizziness, syncope and unstable angina. He underwent a combined surgical procedure of aorto-bicarotid bypass and off-pump myocardial revascularization. The operation was successful and he had no complications during 11 months of follow-up.

Epidemiologic, clinical, and imaging findings in brucellosis patients with osteoarticular involvement.

Objective: The aim of this study was to assess the epidemiologic and clinical features, complications, imaging findings, and outcomes for brucellosis patients with osteoarticular involvement.

Subjects And Methods: This prospective study was performed over 4 years (December 2000-December 2004). The subjects were 251 Turkish patients (age range, 2-77 years) who were diagnosed with brucellosis during that period.

Clinical pattern and abdominal sonographic findings in 251 cases of brucellosis in southern Turkey.

Objective: The aim of this study was to report the clinical features, complications, abdominal sonographic findings, and treatment outcomes for a series of brucellosis cases in southern Turkey.

Subjects And Methods: This prospective study involved 251 patients (age range, 2-77 years) who were hospitalized with brucellosis during a 4-year period. Patients were classified as having acute (< 3 months), subacute (3-12 months), or chronic (> 12 months) disease.

Bilateral parotid gland tuberculosis.

Tuberculosis is caused by a mycobacterium and is one of the most serious diseases in the world. Pulmonary involvement is the most common form of this condition. Primary tuberculosis of the parotid gland is rare.

Successful medical treatment of intracranial abscess caused by Brucella spp.

An unusual presentation of unilateral cerebellar abscesses due to neurobrucellosis observed in a patient is reported. He gave a history of fever, headache, vomiting and had unilateral cerebellar signs. The abscess was detected on magnetic resonance imaging (MRI) and analysis of cerebrospinal fluid revealed neurobrucellosis.

Brachial artery pseudoaneurysm: a rare complication after haemodialysis therapy.

Haemodialysis patients carry a high risk of pseudoaneurysm due to inadvertent puncture of the brachial artery during venous cannulation for haemodialysis. Signs and symptoms are pulsatile mass and a systolic murmur. Complications are rupture, infection, haemorrhage, distal arterial insufficiency, venous thrombosis and neuropathy.

Primary hepatic carcinoid tumor: dynamic CT findings.

Most carcinoid tumors involve the gastrointestinal tract or respiratory system. Primary hepatic carcinoid tumor is a rare entity. A 46-year-old woman presented with abdominal pain, vomiting, and diarrhea.

Radiological findings of primary retroperitoneal synovial sarcoma.

Synovial sarcomas are most commonly localized in the extremities, especially the lower thigh and knee areas. Retroperitoneal synovial sarcoma is very rare. We describe the radiological and pathological findings of an adult retroperitoneal synovial sarcoma.

MRI evaluation of cranial bone marrow signal intensity and thickness in chronic anemia.

Background And Purpose: The aim is to assess the magnetic resonance imaging (MRI) findings for cranial bone marrow (CBM) signal intensity and thickness in patients with chronic anemia and compared these with findings in healthy subjects. We also investigated the relationships between CBM changes and age, type of anemia (hemolytic versus non-hemolytic), and severity of anemia.

Methods: We quantitatively evaluated CBM signal intensity and thickness on images from 40 patients with chronic anemia (20 with congenital hemolytic anemia (HA) and 20 with acquired anemia) and compared these to findings in 28 healthy subjects.

Color Doppler analysis of vertebral arteries: correlative study with angiographic data.

Objective: Color Doppler ultrasonography is the most widespread diagnostic procedure in obstructive disease of the arteries supplying the brain. To our knowledge, there are only a few correlative color Doppler ultrasonographic and angiographic studies of the vertebral arteries, especially in patients who have flow-restrictive stenosis at the carotid bifurcation. The main purpose of this prospective study was to evaluate diameter, flow volume, and time-averaged mean velocities of angiographically verified normal vertebral arteries without collateral flow.

Subclavian steal syndrome from the ipsilateral vertebral artery.

We present two cases of subclavian steal syndrome from the ipsilateral vertebral artery (VA) to the subclavian artery (SCA), one with the left VA originating from the aortic arch and the other with the left VA originating very close to the origin of the SCA, proximal to the occluded segment. In both cases, angiographic demonstration of these anatomic variations and successful endovascular treatment are presented.

Small bowel obstruction due to phytobezoar: CT diagnosis.

Small bowel phytobezoars are rare and are almost always obstructive. The literature contains few reports on the radiological findings for primary small bowel bezoars. There is also very little published on CT results with this lesion, but the features of the scan are characteristic.

Abdominopelvic tuberculosis simulating disseminated ovarian carcinoma with elevated CA-125 level: report of two cases.

We report the radiologic presentations of two cases of peritoneal-pelvic tuberculosis. The initial interpretation based on the adnexal masses, ascites, omental and peritoneal thickening, and elevated serum CA-125 levels led to an erroneous preliminary diagnosis of disseminated ovarian cancer. In both patients, histologic examination showed tuberculosis.
