Immature teratomas (IT) are rare germ cell tumors with malignant behavior, distinct from the benign mature teratomas. Clinical differentiation poses challenges, demanding a comprehensive, multidisciplinary diagnostic approach. This case series delves into the detailed radiological imaging findings of ITs. Pelvic MRI was conducted on five cases with adnexal masses, all of which were histopathologically confirmed as ITs. Radiologically, larger tumor size and scattered fatty components were key diagnostic indicators. This study underlines the importance of comprehensive evaluation in IT diagnosis and management, with MRI as an essential tool in the clinical workflow.

UNASSIGNED: A pure ovarian dysgerminoma in a postmenopausal female is a rare phenomenon.
UNASSIGNED: A 65-year-old female presented with a large pelvic mass. Following surgical debulking, the patient was diagnosed with FIGO Stage IIB ovarian dysgerminoma. She was treated with three cycles of etoposide and cisplatin and has been disease-free for 12 months.
UNASSIGNED: Dysgerminomas in postmenopausal females are uncommon. Gynecologic oncologists should be familiar with the pathological diagnosis and treatment recommendations to achieve optimal outcomes.

We present two cases of 10 and 27 years old girls with recurrence of immature teratoma after an incomplete surgical staging. In both cases, there were huge abdominopelvic masses despite decrease in tumor markers with chemotherapy. Complete surgical resection of these masses was done, and histopathology showed only mature teratoma.

Mature cystic teratomas are the most common ovarian germ cell tumors and represent 70% of the benign ovarian tumors occurring in women under age 30. In less than 2% of cases, these tumors can transform into malignancies. Squamous cell carcinoma arises most frequently from these tumors (in 80% of cases). Intra-peritoneal rupture accounts for approximately 1%-2% of cystic teratoma complications with most ruptures occurring either intraoperatively during laparoscopic surgery or due to trauma. This case report describes the common presentation, imaging, and pathologic findings of a mature cystic teratoma with 2 uncommon associated complications.
