[The accuracy of ultrasound in the diagnosis of intra-abdominal abscess formations].

During the last two years 73 patients with a total number of 84 abdominal abscesses have been investigated by ultrasound. Two thirds of the patients (67%) had postoperative abscesses. Spontaneous abscesses occurred in the remaining 33%. Multiple abscesses occurred in the postoperative group only (7 patients). The overall sensitivity in detecting an abscess was 84%. The sensitivity was much better with spontaneous abscesses (92%) than with postoperative abscesses (80%). One third of the patients have also been investigated by computed tomography. The diagnosis was confirmed either by needle aspiration or by operative drainage. Ultrasound was most useful in detecting abscesses in the right and left upper quadrant and in the pelvis, while CT was superior in the mid-abdomen and when dealing with multiple abscesses.

[Ultrasonic diagnosis in acute right hypogastrium. Attempt at the evaluation of effectiveness].

The diagnostic efficacy of ultrasonography was assessed on the basis of 40 unselected and consecutive patients admitted for acute disorders of the right inferior abdominal quadrant. In this group of patients ultrasonic screening yielded a diagnostic specifity of 0.78 and a sensitivity of 0.92. Knowledge of various anatomical findings and constant training are considered to be of equal importance in order to obtain satisfying results.

[Diagnosis of a colonic lipoma with computer tomography].

This report describes the case history of a woman with a large submucosal tumor in the ascending colon detected by barium enema radiography. Computed tomography (CT) identified the tumor as a submucosal lipoma characterised by its homogeneous fat-equivalent density with a CT number of -95 HU. This case proves that CT can be a definite diagnostic modality for differentiation between gastrointestinal lipomas and other solid or cystic tumors.
