Para ovarian mass of uncertain radiological morphology: A case report.

Presence of endometrial glands within the myometrium represents adenomyosis. On rare occasions, adenomyosis is located outside of the uterine tissue. Consequently, the term extrauterine adenomyoma is given. We present a case of an extrauterine adenomyoma located within the right adnexa which is rare and unique. The history, physical examination and imaging findings were not specific. Furthermore, nonspecific lower abdominal pain was the reason for the patient coming to the hospital and physical examination revealed lower abdominal tenderness. Hence, further imaging was obtained in which a right solid adnexal lesion was seen and consequently an open right oophorectomy and fallopian tube excision was done for the patient. The case was confirmed by histopathology. Multiple imaging modalities are used for masses of extra uterine origin. Possibility of malignancy has been reported and should be kept in mind. Upon searching the literature, there is no reported case noted within Al Hassa-Saudi Arabia. Hence, this is the first case of extrauterine adenomyoma within this region. This case emphasizes the presence of this rare entity and such differential diagnosis should be kept in mind when dealing with such an unusual appearance.
