Female genital tuberculosis is a relatively uncommon form of extrapulmonary tuberculosis that is under-reported and under-recognized. The early course of the disease has fewer manifestations, resulting in late presentation with grave complications like infertility and ectopic pregnancy. Also, difficulty in isolation of the causative bacteria further delays the diagnosis. The radiologist should be well versed with imaging findings of female genital TB to help the clinicians to initiate prompt treatment. This review shall cover imaging findings of female genital TB involving fallopian tubes, uterus, ovaries, cervix, vagina, and vulva on different imaging modalities. Fallopian tubes are almost always involved in genital TB followed by uterus and ovaries. Hysterosalpingogram and ultrasound can best detect tubercular changes in fallopian tubes and uterus whereas cross-sectional imaging is essential for the diagnosis of ovarian or peritoneal TB as they closely mimic malignancy. Cervical, vaginal, or vulval TB produces nonspecific changes and histopathological diagnosis is required for confirmation of the diagnoses. Close differential diagnosis on imaging like malignancy or pelvic inflammatory disease, are also discussed with a brief discussion of the pathogenesis.
