A 38-year-old woman, genitally active, recently diagnosed with breast cancer, in whom a thoraco-abdomino-pelvic CT scan with contrast injection performed as part of the extension workup revealed a right ovarian mass with a fat-liquid level and a round central nodule floating at the fat-liquid interface, giving the appearance of a poke ball (Figure 1).
Poke ball sign is a pathognomonic radiological sign of mature cystic teratoma, characterized by the presence of a single flotting ball at the liquidfat interface. Poke Ball Sign is a variant of «Flotting ball sign» which corresponds to the presence of a variable number of mobile balls within the cystic and fatty contents of an adnexal mass [1]. Mature cystic teratoma is the most frequent benign ovarian tumor in reproductive age women. It is often asymptomatic and discovered incidentally on imaging [2] or more rarely with pelvic pain or complications such as rupture, adnexal torsion or malignant degeneration. To various degrees, these floating balls are constituted by debris of sebum, keratin, fibrin, hemosiderin or fat [3], which influence their disposition in the cystic area and their appearance on imaging. The identification of a floating ball at the fluid-fat interface is often easier on CT and on MRI imaging [4]. Mature teratoma takes on different aspects on imaging, although the poke ball sign is pathognomonic, it has a low sensitivity (25 to 30% in some case series) which explains its absence doesn’t formally eliminate the diagnosis of mature teratoma [1,4].
