OBJECTIVE To present clinical cases of women who had an accessory and cavitated noncommunicating uterine mass with functioning endometrium associated with a normal uterus, suggestive of a new type of Müllerian anomaly. [] Key Method A review of the literature was performed by looking for these terms and others related in MEDLINE. RESULTS Including ours, there are 18 cases in the literature showing an accessory cystic cavity lined by endometrioid epithelium with an otherwise normal uterus.
Accessory and Cavitated Uterine Mass (ACUM) in an 18-Year-Old Woman: A Case Report and Literature Review
Clinical manifestations combined with imaging examinations including ultrasonography, magnetic resonance imaging, and hysterosalpingography are the means to establish a correct diagnosis of ACUM and laparoscopic surgery for complete mass excision is a feasible technique to relieve patient’s symptoms.
Accessory Cavitated Uterine Mass: A Rare Cause of Severe Dysmenorrhea in Young Women.
Diagnosis and laparoscopic excision of accessory cavitated uterine mass in a young woman: A case report
A 22-year-old woman who presented with severe dysmenorrhea and was initially misdiagnosed with cystic adenomyosis is treated with laparoscopic excision and histopathological evaluation for accessory and cavitated uterine mass, which is difficult to diagnose.
Imaging Manifestations of Accessory Cavitated Uterine Mass—A Rare Mullerian Anomaly
MRI is a reliable diagnostic tool for accurate diagnosis of ACUM, and more importantly, in distinguishing it from other causes of chronic pelvic pain like adenomyosis and endometriosis and other imaging differentials likeAdenomyoma, noncommunicating uterine horn, and degenerating leiomyoma.

A rare case study of ACUM, a mullerian anomaly in a 27 years old female with severe dysmenorrhoea with secondary infertility, evaluated and diagnosed as ACUM and vaginal retrieval of the specimen in toto is reported.
Congenital Uterine Cyst, Histology, and Differential Diagnosis of a Pelvic Mass
A 57-year-old woman presented with asimple cystic formation located in the midline of the dome of the uterus, suggesting a simple cyst, but histologic examination revealed the presence of a cystic structure lined by tall ciliated columnar epithelium without atypia, showing a well-developed muscular underlying wall.
Accessory cavitated uterine mass: MRI features and surgical correlations of a rare but under-recognised entity
Pelvic MRI facilitates timely diagnosis and appropriate curative fertility-sparing laparoscopic resection in young women with severe dysmenorrhoea, and ACUM was an isolated round accessory cavitated functional non-communicating horn-like aspect in an otherwise normal uterus.
Difficulties in the Diagnosis of Uterine Congenital Malformations : Ruling out a Unicornuate Uterus
In the study of uterus congenital anomalies, hysteroscopy orhysterosalpingography (HSG) may be carried out to examine the uterus cavity, as well as 3D-ultrasound, magnetic resonance imaging (MRI) or a diagnostic laparoscopy to examined the external surface.
Imaging diagnosis of accessory and cavitated uterine mass, a rare mullerian anomaly
The entity is often under diagnosed; therefore, a high index of suspicion combined with HSG and MRI imaging can help in making an accurate diagnosis.


Uterine-like mass with features of an extrauterine adenomyoma presenting 22 years after total abdominal hysterectomy-bilateral salpingo-oophorectomy: a case report and review of the literature.
A uterine-like mass consistent with an extrauterine adenomyoma presenting 22 years following a total abdominal hysterectomy and bilateral salpingo-oophorectomy is reported.
Uteruslike mass of the ovary: endomyometriosis or congenital malformation? A case with a discussion of histogenesis.
It is believed that a congenital malformation, possibly caused by a defect in fusion of müllerian ducts, should strongly be considered in explaining the pathogenesis of this kind of lesion.

Summary: The aim of this study is to highlight the importance of diagnosing uterine adenomyoma and help in differentiating it from other sinister lesions. Adenomyoma of the uterus is a circumscribed
Isolated adenomyotic cyst associated with severe dysmenorrhea
A case of a 23‐year‐old, nulliparous female with a very rare isolated adenomyotic cyst inducing severe dysmenorrhea, preliminarily diagnosed using MRI as having cavitated rudimentary uterine horn, which excluded the possibility of uterine anomaly.
Uterus-like mass arising in the broad ligament: a metaplasia or mullerian duct anomaly?
A 46-year-old woman presented with a large abdominopelvic mass that arose from the posterior leaf of the right broad ligament, and it is hypothesize that these masses may arise from subperitoneal mesenchymal cells that retain the ability to duplicate mullerian duct structures.
Congenital cysts of the corpus uteri.
Noncommunicating accessory uterine cavity.
Cystic Uterine Tumors
Uterine cystic tumors are uncommon and frequently, non-fibroid swellings are erroneously diagnosed as adnexal enlargements and their true origin only becomes evident during surgery.
