“…Moreover, the ultrasonography found a solid mass with some irregular internal echogenicity, which is suggestive of a dysgerminoma in a young woman,35 and not an inhomogeneous lesion (a mixture of hyperechoic and anechoic tissues), which is suggestive of an ectopic pregnancy.…”

A 24-year-old patient with 7-week amenorrhoea consulted for vaginal bleeding without abdominal pain. Ultrasonography revealed a 7 × 4 cm solid right pelvic mass. There was no visible intrauterine gestational sac. The serum β-human chorionic gonadotropin (β-hCG) level was 11 998 IU/l. Emergency laparoscopy was performed for a presumptive diagnosis of ectopic pregnancy. At laparoscopy, the right ovary was enlarged with a non-haemorrhagic 7 × 4 cm solid lesion, which was resected. The histological diagnosis was a dysgerminoma with immunohistochemistry showing nests of syncytiotrophoblastic cells, which were the origin of the hCG production. There was no pregnancy, either intrauterine or ectopic. There was no evidence of metastasis from the dysgerminoma on the positron-emission tomography scanner. The patient underwent a second procedure for surgical staging of this ovarian germ-cell tumour. This ovarian dysgerminoma was staged FIGO 1A, and the patient did not receive adjuvant therapy. There was no recurrence at the last 8-month follow-up.

“…At Magnetic Resonance Imaging and computed tomography, dysgerminomas also appear as lobulated solid tumors with central areas of necrosis and small specks of calcification [5]. The characteristic features of ovarian dysgerminoma on sonography findings is a purely solid tumor divided into different lobules, with irregular internal echogenicity, with smooth lobulated contours and well defined borders, and richly vascularized at color Doppler examination [6,7].…”

Abstract:The management for ovarian dysgerminoma is different from those of other ovarian tumors, making accurate diagnosis crucial for patient care. We report a case of 9 year old girl who presented with abdominal distension. Examination revealed a huge palpable intra-abdominal mass. Plain X ray abdomen showed a large homogenous mass filling the mid part of the abdomen and causing displacement of bowel loops laterally. Abdominal sonography showed a large heterogenous lobulated abdominal mass reaching up to the pelvic brim. CECT abdomen showed a large well defined lobulated heterogeneously enhancing mass of 59-61 HU occupying most of the mid part of abdomen and reaching up to the pelvic brim. It showed multiple areas of necrosis with few small specks of calcification. The mass was removed after laparotomy under general anesthesia. Finally, after histopathological examination with raised β-human chorionic gonadotropin (β-hCG) levels, the diagnosis of ovarian germ cell tumor (Dysgerminoma) was made.
