Acute appendicitis: MR imaging and sonographic correlation.

OBJECTIVE: Acute appendicitis is the most common indication for emergency abdominal surgery. To our knowledge, MR imaging has not been compared with sonography for revealing acute appendicitis. Our aim was to assess and compare the accuracy, advantages, and limitations of MR imaging and sonography in revealing appendicitis. SUBJECTS AND METHODS: The study included 60 consecutive patients suspected of having appendicitis who underwent abdominal sonography and MR imaging. Fat-suppressed T2-weighted fast spin-echo and gadolinium-enhanced fat-suppressed T1-weighted spin-echo axial and coronal images were obtained. The initial MR imaging and sonographic studies were later correlated with the surgical-pathologic findings, follow-up evaluations, and diagnosis at the time of discharge. RESULTS: Surgical, histopathologic, and follow-up results revealed that 34 patients had appendicitis. Of the 26 patients without appendicitis, 15 with symptoms of acute appendicitis had no pathologic diagnoses and the remaining 11 had another diagnosis. Comparison of the sensitivity, accuracy, and negative predictive values for MR imaging and sonography was found to be statistically significant (p < .05, chi-square test), indicating that MR imaging was superior to sonography in revealing appendicitis. We found no statistical difference in specificity and positive predictive value for MR imaging and sonography. CONCLUSION: Despite some disadvantages, we found MR imaging to be superior to sonography in revealing suspected acute appendicitis. MR imaging can be used after suboptimal or nondiagnostic sonography in cases of suspected acute appendicitis.

[Abdominal pregnancy. Six personal cases].

This study consists of six accurately diagnosed and treated cases of abdominal pregnancy over a 16-year period (1974-1989) in the Obstetrics and Gynecology Department of Cukurova University Medical Faculty in Adana. In this study the incidence of abdominal pregnancy we found was 1 per 4,017 births. In two cases whose pregnancies continued until term, living babies were delivered. The separation of placenta was easy in four cases. However in the other two cases, the management of placenta detachment was difficult because of the stick adhesions with visseria; so in these cases the placenta tissues were left in the abdomen. The methotrexate was administered to eroze to the placenta in these cases. One of them who received methotrexate died of infection.
