[Calcified bladder squamous carcinoma: radiologic considerations]. / Carcinoma escamoso vesical calcificado: consideraciones radiológicas.

OBJECTIVE: To report a case of squamous cell carcinoma of the bladder, an uncommon tumor type, that presented with wide calcified areas. The literature on calcified bladder tumors is reviewed with special reference to the diagnostic aspects. METHODS/RESULTS: The plain film, US and CT findings are presented. All the diagnostic imaging techniques demonstrated calcifications on the tumor surface and the characteristic curvilinear shape of this lesion. CONCLUSIONS: Calcified bladder carcinoma is rare and occurs in only 0.5% of the cases evaluated by conventional radiology. All calcifications probably arising in the bladder detected on conventional radiological evaluation should be studied further with other imaging techniques. If its etiology is unclear, cystoscopy with biopsy and/or a microbiological study should be performed.

[CT in Fournier's gangrene]. / T.C. en la gangrena de Fournier.

OBJECTIVE: To analyze the information provided by computed tomography (CT) in Fournier's gangrene, particularly in regard to the early diagnosis of the disease, and its utility as a complementary diagnostic imaging technique. METHODS: A retrospective study identified five cases of Fournier's gangrene. These patients had been evaluated by CT at least twice. The radiological, clinical and epidemiological aspects are analyzed. RESULTS: Fournier's gangrene was diagnosed in one patient with no clinical suspicion of this disease. Gas was demonstrated in the scrotal region in five patients and in the perineal region in four patients. The abdominal wall was the most frequent extragenito-perineal location. A good correlation was found between the CT and surgical findings in all cases. CONCLUSION: CT evaluation prior to surgery is recommended in patients with Fournier's gangrene, particularly in order to determine the extent of the disease.
