ReviewComputed tomographic and magnetic resonance features of gynecologic abnormalities in women presenting with acute or chronic abdominal pain.
Advances in technology and improved availability have led to increased use of computed tomography (CT) and magnetic resonance imaging (MRI) to evaluate women presenting to the emergency department or to their primary care provider with abdominal and/or pelvic pain. Computed tomographic examinations are often performed to evaluate the presence of appendicitis or renal stone disease. However, gynecologic abnormalities are frequently identified on these examinations. ⋯ If a gynecologic pathology is discovered on CT or MRI, an immediate follow-up ultrasound need not be pursued if the lesion can be characterized as benign, needing immediate surgical intervention, or a variant of normal anatomy. If, on the other hand, findings demonstrate a mass that either is uncharacteristic of a benign lesion, has an indeterminate risk for malignancy, or demonstrates suspicious characteristics for malignancy (such as enhancing mural nodules), further evaluation by serial ultrasound, biochemical marker, and/or CT or MRI is warranted. The purpose of this review is to present a series of commonly encountered gynecologic abnormalities with either CT or MR to make radiologists more familiar with gynecologic pathology on CT and MRI.

Ectopic pregnancy is a major clinical problem, occurring in 75,000 cases per year in the United States. With in vitro fertilization, embryo transfer, microsurgical techniques, and better early diagnosis, the rates of ectopic pregnancies have increased. Transvaginal sonography along with beta-human chorionic gonadotrophin monitoring are the standards for evaluation of suspected ectopic pregnancy. ⋯ Ultrasound is the mainstay of diagnosis, but magnetic resonance imaging can be helpful in unusual or complicated cases. Current therapeutic options for an ectopic pregnancy are expectant management, systemic methotrexate injections, sonographically guided minimal invasive treatment, and surgery. This review encompasses diagnosis, treatment, and management of ectopic pregnancy.
