Primary Malignant Tumor of the Fallopian Tube: CT and MR Features

PURPOSE: To determine the radiologic features of primary malignant tumors of the fallopian tube. MATERIALS AND METHODS: By observing six computed tomograms and one MR image, we determined the radiologic features of seven pathologically proven primary malignant tumors of the fallopian tube. The location, size, internal appearances (cystic/mixed/solid) of the tumor were analysed, and the presence or absence of ipsilateral ovary, hydrosalpinx, intrauterine fluid collection, pelvic ascites and lymphadenopathy were determined. RESULTS: All seven tumors were located in unilateral adnexa. Their mean diameter was 3.5 (range, 1.5-6) cm, and their morphological appearance was solid in five cases and mixed in two. In no case were ipsilateral ovaries identified. Hydrosalpinx was noted in four cases (57%) and intrauterine fluid collection in five (71%). Pelvic ascites and lymphadenopathy were each observed in one case (14%). CONCLUSION: Although it is difficult to differentiate between primary malignent tumors of the fallopian tube and other adnexal tumors, a pelvic mass with hydrosalpinx and intrauterine fluid collection suggests a primary malignant tumor of the fallopian tube.

The Significance of Beaking Sign on Cystography in Stress Urinary Incontinence

PURPOSE: To evaluate the clinical and urodynamic significance of the beaking sign at cystography in patients with stress urinary incontinence (SUI). MATERIALS AND METHODS: We retrospectively reviewed the cystograms of 253 patients with SUI, defining the beaking sign as the triangular contrast collection below the bladder base in the resting state without overt leakage. Various clinical parameters including patient age, symptom duration, parity, the one-hour pad test, and urodynamic study data including Valsalva leak point pressure (VLPP) and maximal urethral closing pressure (MUCP) were compared between the beaking-positive and the beaking-negative group. The distribution of Blaivas type in SUI between these two groups was also analysed. RESULTS: The beaking sign was observed in 153 patients (60%). Those who were older and showed greater parity more often belonged to the beaking-positive group than the beaking-negative (p<0.05). Both VLPP and MUCP were significantly lower in the beaking-positive group than in beaking-negative group (p=0.03; p=0.01, respectively). Type-0 or -I SUI was more common in the beaking-negative group, while the frequency of other types was similar between the two groups. CONCLUSION: The beaking sign has clinical and urodynamic significance, reflecting functional deficiencies of the intrinsic sphincter, and may possibly be regarded as an additional parameter in the planning of treatment.
