METHOD AND MATERIALS Study consisted of two different parts. In the first, 20 patients underwent multidetector CT angiography with 0.3 mmol/kg gadobutrol. 80 kVp setting was used in 10 patients (group 1) and 120 kVp in the remaining 10 (group 2). In the second part, 15 patients with renal artery stenosis (group 3) underwent 0.3 mmol/kg gadobutrol-enhanced multidetector CT angiography using 80 kVp setting. The angiographic images were compared in group 1 and 2 with iodinated contrast-enhanced multidetector CT angiography and in group 3 with digital subtraction angiography. RESULTS When group 1 and 2 patients were compared, Hounsfield Unite values obtained from the abdominal aorta and renal arteries were significantly higher, and renal artery branches were ...

Hamartomas are extrapleural soft tissue lesions that cause rib expansion and destruction and appear on imaging as cystic areas with fluid levels and calcification. They can cause scoliosis, pressure on the neighboring lung parenchyma and mediastinal displacement. While conservative treatment is recommended in asymptomatic cases, growing lesions require surgical excision. In this report, we present the imaging findings in a 3-month-old infant that presented with a firm swelling in the chest wall and was histopathologically confirmed to have a bilateral multifocal hamartoma. Radiological imaging methods are important for accurate diagnosis of this very rare condition that can be confused with a malignancy.

In the literature, pulmonary metastases of meningiomas have been emphasized on their rarity, non-specific imaging findings, and cytologic features. Some definitive MR imaging features of intracranial meningiomas have been described. However, MR imaging findings of the lung metastases of meningiomas have not been investigated with regard to these diagnostic imaging features. In this report, similarities between MR imaging features of primary intracranial meningioma and its rare lung metastases are presented.

The disease usually occurs in children and young adults and frequently ends with death due to progressive course. Imaging findings of the disease are based on lymphatic involvement which appear as mediastinal soft tissue infiltration and thickening of pulmonary peribroncovascular bundles and interlobular septae. In this report, spiral and high-resolution computed tomography, and ultrasonography findings of severe form of this rare disease are presented. Furthermore, some lymphatic disorders, which are called with similar name but different appearances on imaging, are discussed.

Materials and Methods: Seventy-six patients with urinary tract symptoms were evaluated for urinary tract calculi by unenhanced multidetector CT. The examinations were performed with a four-row detector CT scanner. In all patients, two low-dose CT examinations with different kVp and mAs values (120 kVp, 30 mAs and 80 kVp, 95 mAs) were performed. The other scanning parameters were kept constant. Weighted-CT dose index was equal in both examinations. Both CT examinations were quantitatively compared with calculating the HU values of kidneys, subcutaneous fat, calculus, and phleboliths and the HU ratio of urinary calculi to the kidney. Both scans were also qualitatively compared for image quality of upper and lower abdomen. Results: One hundred and two calculi were detected in 50 of 76 patients. One or more phleboliths were present in 20 patients. HU values of the phleboliths and urinary calculi were higher on images obtained with 80 kVp than those obtained with 120 kVp. HU ratio of the calculi to the kidney was higher on scans with 80 kVp. Adipose tissue was less noisy and had lower HU value on 80 kVp images: Image quality of the upper abdomen and major pelvis were better on 80 kVp images, and the majority of these patients were normal (n=28) and overweight (n=20). Minor pelvis mostly (60%) revealed poorer image quality on 80 kVp images. However, the majority were overweight (n=22) or obese (n=6). In patients with osteoporosis, image quality was relatively better when compared with similar weighed patients without osteoporosis on 80 kVp images. Small renal, proximal and middle ureteral calculi were better demarcated on 80 kVp images. Conclusion: Low-dose urinary tract multidetector CT examination with 80 kVp, compared to 120 kVp provides better image quality in the upper abdomen and major pelvis. In overweight and obese patients, minor pelvis may not be evaluated thoroughly on 80 kVp images. Detection of small renal, proximal and middle ureteral calculi could be improved by using 80 kVp setting.

METHOD AND MATERIALS Between August 2006 and March 2010, the patients with the diagnosis of congenital adrenal hyperplasia were retrospectively evaluated for the presence of adrenal rest within the testis. Doppler ultrasound and magnetic resonance imaging findings of the 11 patients with the diagnosis of testicular adrenal rest were documented. Follow up was made by Doppler ultrasound. RESULTS In all 11 patients with the diagnosis of adrenal rest, ultrasound revealed bilateral hypoechoic paranchymal lesions around the mediastinum testis without mass effect. Doppler ultrasound depicted slightly hypervascularity dispersing homogeneously within the lesions in all patients. All lesions were hypointense on T1-weighted MR images. The lesions were slightly hypointense relative to the testicular parenchyma on T2-weighted images....

Most lytic lesions of the skull are benign. Enlarged parietal foramina are benign lesions caused by deficient intramembranous ossification. An 11 month-old female patient was admitted with a mass on the right of the back of the head. Physical examination showed a soft 5 cm mass area with no palpable bone in the right occipital. The family history revealed a similar mass in a maternal cousin that resolved over time. Craniography showed lytic lesions, and there were no other pathologies on a complete skeletal X-ray. Computed tomography (CT) showed regular-shaped defects in the bilateral temporal bones, right parietal bone, bilateral frontal bones in the upper-medial orbital wall, and particularly in the occipital bone. The well-defined contours, absence of a soft tissue component, and normal structure and density of the adjacent calvarial bones all pointed to a congenital defect. No change in the lesions was observed during a three-year ultrasound follow-up period. To the best of our knowledge, this is the first described case of multiple occipital, parietal, temporal, and frontal foramina in the cranium. A diagnosis of enlarged parietal foramina variant should be considered after ruling out the differential diagnosis in patients with multiple calvarial lesions. CT may provide valuable findings for the differential diagnosis, and sonography may be used for follow-up.

After intravenous injection of 0.3 ml/kg gadolinium, the images of the three consecutive acquisitions of the 3D MRVU technique were obtained during voiding. The raw data were reconstructed on all patients for visual analysis. The image quality of the volunteers was technically sufficient to demonstrate normal urethral anatomy. Contrast-enhanced 3D MR voiding urethrography of the urethral strictures was compared with conventional retrograde urethrography (n = 10) and urethroscopy (n = 12). The urethral pathologies including strictures and other obstructive causes of impaired urethral flow were correctly identified on CE 3D MRVU.

The pain was not related with ingestion of foods. A few days later, she developed abdominal distention with shortness of breath. Her vital signs were normal and physical examination revealed hepatomegaly, a distended abdomen, and edema of the lower extremities. Her history was unremarkable except for heavy smoking (30 cigarettes per day), but she denied any alcohol consumption. Laboratory tests revealed normal serum electrolytes, normal liver and renal functions, and a normal blood cell count. Prothrombin time and partial thromboplastin time were measured as 13.9 sec (normal range 11.3-13.3 sec) and 29.9 sec (normal range 24.5-35.2 sec), respectively. An abdominal paracentesis revealed a mild increase of lymphocytes. Serum albumin level was measured as 4.

Endometriosis classically appears on MRI as a mass with a large cystic component and variable signal intensities on T1-and T2-weighted images due to the presence of variable degradation of hemorrhagic products. Endometriosis in an atypical location, an infiltrative appearance and without cystic-hemorrhagic components has rarely been described. We report on a 33-year-old woman with cyclic sciatica due to histologically documented infiltrative endometriosis involving the area of the left sciatic notch.

We report on a 7-year-old girl with osteogenesis imperfecta presenting with hepatomegaly and palpable lymphadenopathy in the left inguinal region on physical examination. Computed tomography examination revealed a high-density mass-like lesion of the manubrium sterni. Ultrasonography and a lateral roentgenogram of the chest verified that this was a pseudomass caused by a bowed sternal manubrium.
