RESUMO

Pulmonary artery (PA) sarcoma is an extremely rare malignant tumor of pulmonary artery. It is often misdiagnosed as pulmonary thromboembolism (PTE) because of its clinical and imaging features which are quite similar to PTE. Multimodality diagnostic imaging and recognition of specific imaging characteristics with appropriate clinical suspicion are required to make correct diagnosis. In this report, we present a case of PA sarcoma with imaging and clinical features as well as emphasize significance of using multimodality imaging.

RESUMO

OBJECTIVES: The purpose of this study was to compare the Precision Imaging sonographic technique (Toshiba Medical Systems Corporation, Tokyo, Japan) with conventional sonography of liver lesions in terms of lesion conspicuity, margin sharpness, overall image quality, and posterior enhancement. METHODS: Sixty-nine focal liver lesions in 60 patients (age range, 14-76 years; mean age, 43 years) were prospectively evaluated. Each lesion was examined with Precision Imaging and conventional sonography. All images were reviewed and graded on a 3-point scale by 2 readers for lesion conspicuity, margin sharpness, and overall image quality. Posterior acoustic enhancement was also analyzed in cystic lesions. A Wilcoxon signed rank test was used for statistical comparisons of the techniques for all parameters. RESULTS: Statistical analysis showed that for margin sharpness, lesion conspicuity, and overall image quality, Precision Imaging was superior to conventional sonography (P< .05). In addition, according to lesion types and dimensions, Precision Imaging was significantly superior to conventional sonography for all parameters. For posterior enhancement, there was no significant difference between Precision Imaging and conventional sonography (P ≥ .05). CONCLUSIONS: In sonography of focal liver lesions, Precision Imaging provides better lesion conspicuity, better margin sharpness, and better overall image quality than conventional sonography. With respect to posterior enhancement of cystic lesions, Precision Imaging is not significantly different from conventional sonography. Precision Imaging may be used as a complementary method in the sonographic evaluation of focal liver lesions.

RESUMO

We describe a rare case of a bilateral peritonsillar cellulitis (PTC). The clinical presentation of fever, trismus and odynophagia was consistent with PTC, more evident on the right side; but the presence of bilateral tonsillar swelling and midline uvula confounded the diagnosis. In spite of the throat examination was performed with a great difficulty due to trismus, the T2 weighted fat saturated STIR magnetic resonance imaging (MRI) guided us to make the diagnosis and to start the intravenous antibiotic treatment immediately.

RESUMO

OBJECTIVE: The objective of this study was to investigate the value of contrast material-filled virtual cystoscopy in the detection of bladder tumors. MATERIALS AND METHODS: Thirty-nine patients who had recent diagnosis or were followed up due to priory history of bladder tumor underwent virtual cystoscopy. After the intravenous injection of contrast medium, the bladder was examined with helical computed tomography (CT) scan. The data were transferred to a workstation for interactive navigation using surface rendering. Two radiologists independently interpreted the axial and virtual images, and discrepancies were resolved by consensus. The results of virtual cystoscopy were compared with the findings of conventional cystoscopy. RESULTS: Forty-nine of 54 bladder lesions detected with conventional cystoscopy in 33 patients were also shown on virtual images. On virtual cystoscopy, three of the seven lesions 5 mm or smaller in diameter could be identified. There were no false-positive findings. The sensitivity of the technique was 96.2% for polypoid tumors and 88.9% for sessile lesions. When axial and virtual images were evaluated together, the sensitivity rate increased to 94.4%. CONCLUSION: Bladder tumors can be diagnosed noninvasively using contrast medium-filled virtual cystoscopy. Evaluation of both the axial and virtual images increases the sensitivity of the technique.

RESUMO

Metastatic tumors of the clitoris are extremely rare. We report a case of clitoral metastasis in a 75-year-old woman who was treated for transitional cell carcinoma of renal pelvis 2 years ago. The computed tomography and magnetic resonance imaging findings are presented with a short review of the literature. To the best of our knowledge, clitoral metastasis originating from transitional cell carcinoma of the renal pelvis has not been reported in the English language literature.

RESUMO

Cemento-ossifying fibroma is a benign fibro-osseous tumor which contains fibrous tissue and varying amounts of calcified tissue resembling bone, cementum or both. The tumor is frequently seen in the mandibula and maxilla, but it may rarely affect the ethmoidal sinus. In this report, CT findings of cemento-ossifying fibroma located in the ethmoidal sinus are presented.
