Bottom Line: All three masses had a similar morphology, i.e. a para-ovarian uni-locular tubular mass with a color score of 1.A typical characteristic was the aspect of the cyst content, which resembled whipped cream.MA is a -para-ovarian, unilocular tubular mass that typically has a cyst content that resembles whipped cream.

ABSTRACT
The aim of this pictorial essay is to describe the ultrasound characteristics of the mucocele of the appendix (MA) by transvaginal ultrasound. The databases of the pathology and gynaecology departments of two Belgian hospitals were retrospectively searched for all cases of MA. Only patients who received a pre-operative transvaginal ultrasound scan by an experienced ultrasound examiner following the IOTA protocol were included. Ultrasound -characteristics were described and pattern recognition was applied in order to find morphological characteristics typical for MA. Thirty-one cases were found of which five underwent a transvaginal ultrasound. In three out of these five cases a mucocele was described. All three masses had a similar morphology, i.e. a para-ovarian uni-locular tubular mass with a color score of 1. A typical characteristic was the aspect of the cyst content, which resembled whipped cream. Although MA is seldom diagnosed by gynaecologists, transvaginal ultrasound is able to make an accurate diagnosis. MA is a -para-ovarian, unilocular tubular mass that typically has a cyst content that resembles whipped cream.

Mentions: Database search retrieved 31 cases of MA of which five patients received a preoperative transvaginal ultrasound. One out of the five cases was excluded because this patient had - beside the MA, a concomitant stage IV ovarian cancer and the MA was not recognized as such during the ultrasound and therefore also not described in the report. A second case was excluded because only a peritoneal pseudocyst was visualised on ultrasound, but no other mass. In this patient, the diagnosis of a small MA was a coincidental finding during surgery. The remaining three patients were referred for a transvaginal ultrasound examination because ovarian pathology was suggested during previous examinations. One out of the three patients was asymptomatic and the diagnosis of MA was made during a routine gynaecological check-up (Fig. 1). In the second patient, an ovarian mass was visualised on CT scan, performed for vague gastro-intestinal complaints (Fig. 2) and the third patient was referred because of right fossa pain (Fig. 3). Demographich, clinical and sonographic characteristics are listed in Table I. All three masses presented with the same morphology i.e. a para-ovarian, unilocular, tubular masses with a color score of 1 (no flow visualised) (Table I). The median largest diameter was 72.6 mm (50-108 mm). A characteristic for MA that was found after pattern recognition was the aspect of the cyst content, which resembled whipped cream (Fig. 4). In all three cases the correct specific histologic preoperative diagnosis of MA was suggested by the sonologist. None of the masses was included in any of the IOTA studies since a mass that is presumed to be non-adnexal cannot be include
