Salmonella infection of ovarian dermoid cyst

Ovarian Endometrioma Superinfected With Salmonella: Case Report and Review of the Literature

We present the case of a 28-year-old woman with Salmonella serovar Schwarzengrund gastroenteritis acquired during foreign travel. Her case was complicated by superinfection of a pre-existing ovarian endometrioma with a quinolone-resistant organism; the resultant ovarian abscess ultimately required surgical removal for resolution. We review the key features of this case and the previous literature on Salmonella ovarian abscess. This report highlights (1) the potential for metastatic spread of Salmonella to the ovary in women with pre-existing cysts or endometriomas and (2) the increasing worldwide burden of quinolone-resistant Salmonella.

Imaging of ovarian teratomas: appearances and complications

Ovarian teratomas are the most common germ cell neoplasm. Subtypes of teratoma include mature cystic, immature and the monodermal teratomas. The benign cystic teratoma shows typical imaging manifestations and can be complicated by torsion, rupture and uncommonly malignant degeneration. Uncommon subtypes of teratomas include the immature, which is usually malignant at diagnosis. The growing teratoma syndrome is an uncommon complication reported in patients treated for immature teratomas. The monodermal teratomas which include the struma ovarii may also have specific imaging characteristics that should be recognised on imaging. This paper aims to provide a comprehensive review describing the spectrum of imaging findings of these ovarian tumours and associated complications.

Imaging findings of complications and unusual manifestations of ovarian teratomas

Ovarian teratomas can be associated with various complications and demonstrate a wide spectrum of clinical and imaging features. The complications include torsion (16% of ovarian teratomas), rupture (1%-4%), malignant transformation (1%-2%), infection (1%), and autoimmune hemolytic anemia (<1%). These complications require different therapeutic strategies; therefore, timely and accurate diagnosis of these complications is important for optimal patient treatment. In cases of complicated ovarian teratomas, the clinical manifestations provide only limited information and often overlap with those of other diseases. Furthermore, ovarian teratomas may have unusual clinical and imaging manifestations, thereby leading to misdiagnosis. These unusual manifestations include immature teratomas, monodermal teratomas (struma ovarii), combination tumors and collision tumors containing teratomas, and mature cystic teratomas without demonstrable fat or with pure fatty components. To provide adequate treatment and prevent misdiagnosis, it is necessary to be familiar with the imaging findings of both the complications and the unusual manifestations of ovarian teratomas.

Salmonella enteritidis in an endometriotic ovarian cyst

Isolated Salmonella infections are rare. In view of the rarity, we present a case of a 16-year-old patient with an endometriotic ovarian cyst where Salmonella enteritidis was isolated from aspirated material from the cyst. We include a review of the world literature on ovarian Salmonella infection from 1966 to June 1996.
