There are very few reports in the literature of UGS with hydrometrocolpos diagnosed in utero. We describe four cases of portal vein aneurysm that were studied with ultrasonography, color Doppler, computed tomography, and magnetic resonance imaging as well as three-dimensional power Doppler. Pancreatic metastases are rare. Urinary hydrometrocolpos by persistent urogenital sinus; prenatal diagnosis and neonatal management]. The CT scans demonstrated unilateral involvement of the vidian nerve in 9 patients. The presence of a fluid-debris level inside the cystic anechoic mass must be considered a crucial finding. Eighty consecutive children were prospectively studied with contrast-enhanced second-harmonic VUS.
Our purpose is to describe the imaging features in athletes with chronic lower leg pain, emphasizing the role of MRI and CT, which are the diagnostic tools with the highest sensitivity and specificity in the differential diagnosis of lower leg pain. Growing requests by paediatric nephrologists and surgeons require that even general radiologists become familiar with this technique. The aims of this article are to describe the findings of perividian tumor spread and to compare the accuracy of MRI and CT in diagnosing perineural metastasis along the vidian nerve. McNemar test was used to detect statistically significant differences. Contrast-enhanced voiding urosonography VUS is largely accepted both for the diagnosis and follow-up of vesicoureteric reflux VUR in children.

Plain radiography has a low sensitivity but may reveal tibial stress fractures, bone tumors, and soft-tissue calcification. Ten patients met the selected criteria for perineural metastasis, cuericulum was bilateral in 3 patients, with a total of 13 vidian metastases. Histology showed recognizable seminiferous tubules and Leydig cells. Estimated average dose calculated from phantom study was 0. The xurriculum of significant disease detected by CT-CA was not negligible in asymptomatic patients.
McNemar test was used to detect statistically significant differences. The aims of this article are to describe the findings of perividian tumor spread and to compare the accuracy of MRI and CT in diagnosing perineural metastasis along the vidian nerve.

Sensitivity in detecting stones, strictures and congenital ureteropelvic junction obstructions was respectively Medical ethics committee approval and informed consent were obtained. The Authors report their experience on 3 cases of UGS without ambiguous genitalia with hydrometrocolpos, in which prenatal sonography had shown a cystic dilatation in radoologia pelvis.
There are very few reports in the literature of UGS with hydrometrocolpos diagnosed in utero. Pancreatic metastases are rare. Three-dimensional ultrasonography showed the portal aneurysm and its relationship to its portal branches in all radillogia and showed the portosystemic communication in three.
Multiple echoes are due to vaginal secretions.
Perineural spread along the vidian nerve is an event more frequent than previously reported and must be investigated with a careful imaging technique. Multiple hypervascular pancreatic metastases from renal cell carcinoma: The MRI scans showed 13 perineural metastases.
Ten asymptomatic volunteers served as the control group. We evaluated the distance between the TMJ disk and the mandibular nerve at the oval foramen level.
Combined MRU and short helical CT has a high sensitivity in detecting ureteral calculi with a reduced radiation dose. Significant difference in detection of early tibial stress injuries was found between MR imaging and both CT and bone scintigraphy McNemar test; P Combined magnetic resonance urography and targeted helical CT in patients with renal colic: The aim of our paper is to review the role of ultrasonography in the diagnosis of VUR, from the initial experiences up to the recent use of second-generation microbubbles combined with contrast-specific low-mechanical-index software.
We present US and CT findings of a pancreatic tail pseudocyst extending into the subcapsular space of the left kidney. Voiding cystourethrogram, genitography and genitoscopy confirmed the presence of an UGS with urinary retention inside the vagina and stenosis of the distal portion of the vagina itself.
Although a major limitation of our study is the lack of histological proof, the MR finding of a significant enhancement of the nerve, whether enlarged or normal in size, could be considered very suggestive of this kind of metastatic spreading, particularly if associated with simultaneous involvement of the neighboring structures pterygopalatine fossa, foramen lacerum, trigeminal branches, etc.
We describe four cases of radiolotia vein aneurysm that were studied with ultrasonography, tecnco Doppler, computed tomography, and magnetic resonance imaging as well as three-dimensional power Doppler.
We present three cases of multiple hypervascular pancreatic metastases from renal cell carcinoma, studied with spiral CT and dynamic MR. Urogenital Sinus UGS malformation can be ascribed to an arrest of normal embryonic vaginal development.
The CT and MR examinations of 98 consecutive untreated patients with histologically proven head and neck cancer were retrospectively reviewed. Imaging of the normal posterior urethra was skilfully demonstrated with US in 15 young boys with VUR.
Moreover, a diagnostic algorithm in patients with chronic lower leg pain is proposed. Prenatal ultrasound has then a definitive role in detecting an obstructed genital tract.
We discuss the advantages and limits of VUS with respect to radiographic and radionuclide imaging in the light of an analysis of the most recent literature, and we described the new VUS study technique using second-generation contrast media.
A second-generation US contrast medium such as SonoVue, if available, should be the first choice as the dose required for one examination is much lower and consequently significant reduction of contrast agent cost is possible.
To evaluate the usefulness of contrast-enhanced second-harmonic VUS in the diagnosis and grading of VUR, using a second-generation contrast agent. CT and MRI may be useful to better evaluate the abnormalities shown by plain radiography.
