ABSTRACT
The diagnosis of urethral diverticula in women can be difficult. Several imaging modalities have been described for evaluating this entity: urethrography; transabdominal, transrectal, transvaginal, and transperineal ultrasonography; computed tomography (CT); and magnetic resonance (MR) can be helpful in evaluating a diverticulum and its relationship to the urethra. We report on four women aged 36 to 42 years with urethral diverticula. Transrectal ultrasonography (TRU) was the most useful diagnostic test in our series. TRU showed 7 urethral diverticula and provided information about its shape, volume, and content as well as its spatial relationship about its shape, volume, and content as well as its spatial relationship to the urethra. In two cases, multiple diverticula were detected when only a single lesion was clinically suspected. Transabdominal sonography failed to demonstrate small diverticula. CT examination did not provide additional information except for the passage of the contrast from the urethra to the diverticulum in one of the cases. Voiding cystourethrogram was positive in only one patient.

We describe a case of laryngeal amyloidoma in a 39-year-old man in whom CT examination disclosed a calcifield soft-tissue mass arising in the epiglottis. The presence of focal calcifications suggested a cartilaginous tumor.

We retrospectively analyzed six cases of abdominal cystic lymphangiomas (CL), who had undergone surgical resection. These cases had been evaluated by several modalities: ultrasonography (US), computed tomography (CT), angiography and fine needle aspiration. No age predilection was found. All patients were symptomatic. The most common presenting symptoms were abdominal pain (66%), palpable mass (66%), fever (50%) and vomiting (30%). US showed septations (85%) and unicameral mass (15%); in three cases (50%) echogenic material within the cyst was found, probably due to hemorrhage and infection. CT showed capsular enhancement in all cases. Capsular and septation thickness were slightly increased in cases of infection or bleeding. At CT the contents were usually of fluid attenuation (66%); in 33% the attenuation values were higher, probably because of internal bleeding and infection. US was superior to CT in the demonstration of septations and the internal nature of the cysts. The major role of imaging is to demonstrate the cystic nature of these abdominal masses, because they do not have specific signs or symptoms that could allow a clinical diagnosis.
