Imaging in gynecological disease (5): clinical and ultrasound characteristics in fibroma and fibrothecoma of the ovary

Abstract

Objectives

A rare case of primary ovarian leiomyoma with atypical Meigs' syndrome

“…Ultrasound has been well documented as the best diagnostic modalities for pelvic organ masses, but in ovarian leiomyomas, it is diffi cult to distinguish ovarian leiomyomas from other ovarian tumors. Even on abdominopelvic CT, it is difficult to distinguish ovarian leiomyomas from other ovarian masses, and in some cases, the ovarian mass is reported as malignancy [8]. In addition, there were some cases misdiagnosed as an ovarian fi broma even though it will be revealed as an ovarian myoma on fi nal pathology as our case showed.…”

“…The tumor cells were strongly positive for reticulin and the tumor was confi rmed as leiomyoma (Fig. 5) [6][7][8].…”

An uncommon entity of primary ovarian fibroid: a case report

“…Even on CT of abdomen and pelvis, it is difficult to distinguish ovarian fibroids from other ovarian masses, and sometimes, the ovarian mass is reported as a malignancy. 20 The histogenesis of ovarian fibroid is not well known. Some theories hypothesize that the tumor may originate from hilar blood vessels, smooth muscle metaplasia of ovarian stroma, or smooth muscle-like theca externa cells.…”

Twisted Ovarian Fibroma Mimicking as an Ectopic Pregnancy

“…The fibroma arises from spindle cells which produces collagen. It is the commonest subtype of the sex cord-stromal tumors [2]. The mean age at diagnosis is 48 years and 90% of patients are at least 30 years old when they are diagnosed with fibroma [3].…”
