@entity18767 following XXXX : CT usefulness in the diagnosis.

PURPOSE: The @entity397 of an @entity42 is among the most frequent causes of @entity18767 in @entity1 , and especially in young @entity1 . An ultrasound (US) examination performed in emergency allows the easy detection of fluids leaking into the abdomen. It may however be difficult to establish whether this fluid is blood and identify the cyst or the signs of a @entity397 . The aim of the present study was the assessment of CT diagnostic capabilities in cases of @entity18767 following @entity397 . MATERIALS AND METHODS: CT abdominal studies performed in emergency in 15 @entity1 with surgical findings of @entity42 and consequent @entity18767 were retro-spectively reviewed. An ultrasound examination carried out in 12 @entity1 was positive in all cases for abdominal effusion, without however confirming the presence of an @entity42 or without definitely defining the @entity397 . Spiral CT examinations were performed with a preliminary unenhanced study of the abdomen (10-mm thickness image acquisitions, 10-mm intervals) and with scans obtained after injection of 150 cc of contrast medium (c.m.) at the speed of 2 cc/sec, 60-sec delay; late-phase acquisition scans of the pelvic cavity were obtained in eight of the 15 @entity1 . RESULTS: CT imaging allowed the depiction of the effusion in all cases. This was limited to the pelvic cavity in five cases and extended to the upper abdomen in the remaining ten @entity1 ; in seven of these ten cases, a difference in the density between the upper abdomen and the pelvic cavity was detected. An @entity42 was visualized in 11 @entity1 ; in eight of them, an irregular opacification of the walls was recorded, suggesting the diagnosis of @entity397 . In the remaining four cases, a c.m. extravasation was observed, starting from the adnexal region, intracystic in one of them. In all these @entity1 , a hyperdense collection in the pelvic cavity was documented in late-phase acquisitions. DISCUSSION AND CONCLUSIONS: CT imaging in cases of @entity548 due to @entity42 permits the acquisition of useful diagnostic information: a different effusion density in the pelvic cavity and in the upper abdomen, the direct visualization of the @entity3928 (even when involved in a large effusion), the irregularity of opacified cystic walls (a sign of @entity397 ), and finally, the direct extravasion and collection of the c.m. in the pelvic cavity. These is fundamental information in those cases in whom US findings are negative or doubtful.
