RESUMEN

PURPOSE: We wanted to evaluate whether both the colonic transit time (CTT) and defecography are necessary for diagnosing constipated patients, and we also wanted to assess the defecographic findings of patients with outlet obstruction on CTT. MATERIALS AND METHODS: Over the recent 3 years, 26 patients (21 women and 5 men, mean age: 59 years) underwent both CTT and defecography because of their chronic constipation or defecation difficulty. The mean interval between the 2 studies was 48 days. Colonoscopy, barium enema and manometry were performed in 22, 8 and all the patients, respectively. RESULTS: On CTT, 13 patients (50.0%) were normal and 13 patients (50.0%) were abnormal; the abnormal results were composed of outlet obstruction (n=8, 30.8%), outlet obstruction and colon inertia (n=2, 7.7%), colon inertia (n=2, 7.7%), and outlet obstruction and hindgut dysfunction (n=1, 3.8%). On defecography, 6 patients (23.1%) were normal and 20 patients (76.9%) were abnormal; the results were composed of rectocele (n=8, 30.7%), rectocele and perineal descent syndrome (PDS; n=4, 15.4%), PDS and rectal intussusception (n=3, 11.5%), spastic pelvic floor syndrome (SPFS; n=3, 11.5%), rectocele and SPFS (n=1, 3.8%), and rectal intussusception (n=1, 3.8%). Of the 11 patients with outlet obstruction on CTT, rectocele (n=4, 36.4%), SPFS (n=1, 9.1%), rectocele and PDS (n=1, 9.1%), and PDS and rectal intussusception (n=1, 9.1%) were demonstrated on defecography, except for the 4 normal cases. CONCLUSION: Both CTT and defecography were necessary for diagnosing the patients with chronic constipation in compensation, and 63.6% of the patients with pelvic outlet obstruction showed an abnormal pelvic defecation function.

RESUMEN

Nodular hepatic involvement of multiple myeloma is very rare. We report here on a case of nodular hepatic involvement of multiple myeloma that mimicked intrahepatic cholangiocarcinoma. In patients with multiple myeloma, hepatic involvement of the multiple myeloma might be included in the differential diagnosis of hepatic mass.

RESUMEN

PURPOSE: To evaluate the ultrasonographic (US) or computer tomography (CT) findings of surgically proven epidermal cysts in the trunk, and to compare the echogenicity of cysts with internal contents. MATERIALS AND METHODS: Forty-five patients were retrospectively evaluated. US and CT findings of epidermal cysts were assessed in regard to location, size, shape, number, echogenicity, posterior sound enhancement, internal density, septa, mural nodule and calcification, perilesional infiltration, contrast enhancement, and internal contents. RESULTS: All 45 patients (M: F=29: 16; US in 26, CT in 19) had only one cyst, and they were located in the buttocks (n=19), back (n=13), inguinal (n=4), posterior neck (n=3), perineum (n=2), abdominal wall (n=2), presternal (n=1), and axilla (n=1). Of 26 patients who underwent US, there were 8 cases of homogeneously hypoechoic mass (30.8%), 8 of inhomogeneously hypoechoic mass (30.8%), 7 of homogeneously hypoechoic mass with internal hypoechoic lines and echogenic spots (26.9%) and 3 of homogeneously hypoechoic mass with internal echogenic spots (11.5%). Posterior sound enhancement was noted in 21 patients (80.8%). Of 19 patients who underwent CT, there were 14 cases of simple cyst (73.7%) and 5 of abscess-like lesion (26.3%). Overlying skin thickening (n=13), contrast enhancement of cystic wall (n=11), perilesional infiltration (n=7), and internal septa (n=6) were demonstrated. The internal contents of the cysts were keratinous (n=27, 60.0%) or greasy (n=15, 33.3%) material. There was no statistical significance between the echogenicity of the cysts and the internal contents (p >0.2). CONCLUSION: Epidermal cysts showed homogeneous or inhomogeneous hypoechoic mass with posterior sound enhancement on US. There was no relationship between the echogenicity of the cysts and the internal contents. In the case of ruptured cyst, an abscess-like lesion with wall enhancement and perilesional infiltration was noted on CT scan.
