Dropped gallstones is a rare complication after a cholecystectomy. Computed tomography is the modality of choice for diagnosis. Dropped gallstones can be a fortuitous discovery in an asymptomatic patient but it is usually revealed when a complication occurs, most commonly through an abscess. Our case presents a dropped gallstone found during a routine check-up in a patient with a history of small bowel cancer. We will discuss differential diagnosis with others calcified peritoneal nodular patterns, particularly peritoneal carcinomatosis. We will recall the multimodality imaging findings of dropped gallstone and, based on literature, we will review the different sources of calcified peritoneal nodular pattern. The treatment of gallstone drop consequences depends on the clinical aspect.

BackgroundMenstrual cups are increasingly used as alternatives to tampons, collecting menstrual fluid with very few side-effects, as previously reported in the literature.CaseWe present the case of a 47-year-old woman with pain in her right flank and an entrapped bladder caused by an incorrectly placed menstrual cup, complicated by acute unilateral hydronephrosis. We describe the computed tomography features that made it possible to make a correct diagnosis. We conducted a literature review in order to be able to list the reported side-effects of the use of menstrual cups.ConclusionGiven their common use today, it is important that physicians become familiar with menstrual cups and are capable of recognizing cup misplacement to avoid complications such as hydronephrosis.

The arcuate line hernia is an, usually asymptomatic, ascending protrusion of intra peritoneal structure under the fold of Douglas, classified into three types depending on its severity and the degree of complication.We report a case of a 64-year-old Caucasian woman whose diagnosis of arcuate line hernia was initially missed at a computed tomography and diagnosed 3 weeks later on the repeat computed tomography scan when an intrahernian necrosis of the epiploic fat appeared.The present case discusses the classical anatomical and radiological features. The therapeutic approach is based on laparoscopic surgery.
