The prognostic significance of vascular (blood and lymphatic vessels) invasion was evaluated in a retrospective review of 27 patients with upper urinary tract transitional cell carcinoma from January 1985 to December 1993, who underwent a nephroureterectomy with bladder cuff resection. Vascular invasion was found in 10 patients (37%). The incidence of vascular invasion was well correlated with tumor grade and stage. The incidence of postoperative metastases was significantly higher in the patients with (70%) than without (17.6%) vascular invasion (p<0.05). The survival rate of the patients with vascular invasion was significantly lower than in those without vascular invasion (p<0.01). In multivariate Cox`s regressional analysis the prognostic value of vascular invasion was independent of tumor grade and stage. These results indicate that vascular invasion should predict a more unfavorable outcome in patients with upper urinary tract transitional cell carcinoma as an independent morphological indicator.

When a soft tissue mass in the bony wall of the paranasal sinus is present, it is difficult to make a distinction between tumor and inflammatory mass on CT. Fungal sinusitis may have soft tissue attenuation on the bony wall of the sinus, bony sclerosis, focal bony destruction, and calcific area on CT. This is a report of four proven cases of fungal sinusitis, asperogillosis in 3 cases and mucormycosis in 1 case, All 4 patients had CT and one patient had MRI, On CT, bony sclerosis and destruction were well visualized in all cases. On MRI, mycetoma in the maxillary sinus was hypointense on T1 weighted images and more hypointense on T2 weighted images. Although CT appears to be the best modality for initial examination of the patient with sinusitis, the differentiation of fungal sinusitis from tumor mass or other entity may be better accomplished with MRI.
