Isolated adenomyotic cyst associated with severe dysmenorrhea

Abstract

A case of a 23-year-old, nulliparous female with a very rare isolated adenomyotic cyst inducing severe dysmenorrhea was seen. Transvaginal ultrasonographic tomography and magnetic resonance imaging (MRI) showed a 3 x 3-cm cystic mass within the left anterior wall of the uterine corpus. The cystic space was filled with hyperintense fluid on T1-weighted images, which was surrounded by hypointense tissue beside the right uterine corpus on T2-weighted images. The case was preliminarily diagnosed using MRI as having cavitated rudimentary uterine horn. However, hysterosalpingography excluded the possibility of uterine anomaly. A hemorrhagic adenomyotic cyst measuring 3 cm within the left anterior wall of the uterine corpus was surgically removed. There was no evidence of diffuse adenomyosis uteri. Dysmenorrhea completely disappeared postoperatively.

Adenomyotic Cyst in a 25-Year-Old Woman: Case Report

“…Several terms have been used to define these large cysts including adenomyotic cyst [6][7][8], cystic adenomyoma [9][10][11], and cystic adenomyosis [12,13]. According to Takeuchi et al [14], adenomyoma is a neoplastic tumor classified as a benign mixed epithelial-nonepithelial tumor.…”

A case of cystic adenomyosis presenting as uterine malignancy on gross appearance

“…But after operating, they found a hemorrhagic adenomyosis cyst measuring 3 cm within the left anterior wall of uterine corpus. 2 Ho ML et al also reported a similar case where ultrasonography demonstrated a large cystic lesion, which was localised to the myometrium on CT scan and MRI; the lesion was diagnosed to be cystic adenomyosis by pathology after surgical resection.…”

Adenomyotic cyst of the uterus associated with pelvic pain: A case report

“…Adenomyotic cysts are usually observed in parous women, and usually seen in association with diffuse adenomyosis uteri [3]. But isolated adenomyotic cysts may also be detected [4,5]. Adenomyotic cysts are usually seen in older ages but they may be even detected in adolescents [5].…”

“…But even urinary retension may be the symptom of an adenomyomatous polyp [8]. Pain or severe dysmenorrhea may also be the main symptom in adenomyotic cysts [2,4,5]. This patient had also pelvic pain as the main symptom accompanied by dysmenorrhea and postcoital pain.…”

“…Magnetic resonance imaging can easily differentiate multiple cysts within the uterine myometrium, but hysterosalpingography may also be useful for the differential diagnosis when magnetic resonance imaging cannot differentiate isolated adenomyotic cyst from cavitated noncommunicating rudimentary uterine horn [4].…”
