A rare case of collision tumour of the ovary complicated by torsion

Collision tumour is the coexistence of two adjacent, but histologically distinct tumours without histologic admixture. Collision tumours are rare in the ovary. It is mostly a histopathological diagnosis often missed in preoperative imaging. The radiologist, gynaecologists and pathologists should be aware of such a combination of tumours to avoid misdiagnosis. We describe the finding of a rare collision tumour, mature cystic teratoma and ovarian fibroma complicated by torsion.

GIANT OVARIAN FIBROMA WITH ASSOCIATED PSEUDO-MEIGS' SYNDROME: A CASE REPORT AND LITERATURE REVIEW

Meigs' syndrome is a rare condition characterized by the presence of a benign broma of the ovary, ascites and pleural effusion. When either of ascites or pleural effusion is associated with the broma it is termed pseudo-Meigs' syndrome. Though bromas are the most common benign solid tumours of the ovary, they rarely present in clinical practice and diagnosis is made difcult by symptoms that usually mimic disseminated malignancy. The gold standard of treatment is laparotomy, denitive diagnosis is by histology, and by denition of the syndrome, the symptoms resolve after removal of the tumour and the patients become asymptomatic. We present a patient with a giant ovarian broma with associated pseudo Meigs syndrome who was successfully managed without any complications.

Meigs syndrome revealed by bilateral ovarian fibroma in postmenopausal woman

Ovarian fibroma is one of the rarest solid tumor of the ovary. When it is associated to ascites and to a pleural effusion it realized the rare entity known as Demons Meigs’ syndrome. The diagnosis of this type of tumors is often difficult and it is usually diagnosed through histopathological examination. A malignant tumor must be eliminated especially when it’s associated to an elevated CA 125 serum level. It is confirmed by histopathological examination of surgical specimen. Surgery is the unique treatment of this syndrome by removing the ovarian fibroma (cystectomy) in young women or by salpingo oophorectomy in old one. The resolution of peritoneal and pleural effusion after tumors removing without recurrence confirmed the diagnosis of Meigs syndrome. We report a case of Meigs’syndrome in post-menopausal woman revealed by bilateral ovarian fibroma associated to elevated CA125 serum level mimicked an ovarian malignancy process.
