Adenomyosis on MRI
Published 17 May 2014
Endometriosis is a common and clinically important problem in women of childbearing age. It is classically defined as the presence of functional endometrial glands and stroma outside the uterine cavity and musculature 1. This is distinct from adenomyosis, in which endometrial tissue is confined ...
Adenomyosis of the uterus
Adenomyosis of the uterus is a common, benign uterine pathology. It is thought by many to be on the spectrum of endometriosis, with ectopic endometrial tissue in the myometrium. Adenomyosis may present with menorrhagia and dysmenorrhea. Ultrasound and MRI are imaging modalities that may show cha...
An arcuate uterus is a mildly variant shape of the uterus. It is technically one of the Müllerian duct anomalies, but is often classified as a normal variant. It is the uterine anomaly that is least commonly associated with reproductive failure. Arcuate uterus can be characterised with ultrasoun...
MRI reporting guidelines for cervical cancer
MRI reporting guidelines for cervical cancer help maintain uniformity of reports and assessment of important imaging staging criteria. Tumour size The tumour should be measured in three orthogonal planes. Tumours with a maximum diameter >4 cm are usually not amenable to primary radical surgery...
Endometriomas, also known as chocolate cysts or endometriotic cysts, are a localised form of endometriosis and are usually within the ovary. They are readily diagnosed on ultrasound, with most demonstrating classical radiographic features. Epidemiology These occur women of reproductive age. ...
Ovarian cystic neoplasms
Ovarian cystic neoplasms can be either benign or malignant and can arise from epithelial, stromal, or germ cell components. In general, the risk of malignancy in unilocular cystic tumours <10 cm in women over 50 is thought to be low 3-4. benign ovarian mature cystic teratoma cystadenomas ser...
Ovarian serous cystadenoma
Ovarian serous cystadenomas are a type of benign ovarian epithelial tumour at the benign end of the spectrum of ovarian serous tumours. Epidemiology Serous cystadenomas account for ~60% of ovarian serous tumours 1. They are the commonest type of ovarian epithelial neoplasm. The peak incidence ...
A haematosalpinx refers to intraluminal blood within the Fallopian tube (often dilated). Pathology Causes include tubal ectopic pregnancy: common cause 1 endometriosis: common cause 5 tubal carcinoma pelvic inflammatory disease fallopian tube torsion retrograde menstruation uterine cer...
Hydrosalpinx is a descriptive term and refers to a fluid filled dilatation of the fallopian tube. Clinical presentation Patients may be asymptomatic or may present with pelvic pain or infertility. Pathology One or both fallopian tubes may be affected. A hydrosalpinx results from an accumula...
Epithelial ovarian tumours
Ovarian epithelial tumours account for the majority of all ovarian tumours (60-70%) and their malignant forms represent >90% of ovarian cancers 1. They can range from being benign to highly malignant. Epidemiology There is a difference in frequency of ovarian tumour subtypes depending on menop...
Ovarian serous cystadenocarcinoma
Ovarian serous cystadenocarcinoma is an ovarian epithelial tumour at the malignant end of the spectrum of ovarian serous tumours. Epidemiology They account for the largest proportion of malignant ovarian tumours 1, representing over 50-80% of all malignant epithelial ovarian tumours 4. The pre...
Ovarian mucinous tumours
Ovarian mucinous tumours are a subgroup of ovarian epithelial tumours. They represent ~20% of all ovarian tumours and ~10% of all malignant ovarian tumours. They are subdivided according to their malignant potential and clinical behaviour into: ovarian mucinous cystadenoma ovarian borderline m...
Ovarian mucinous cystadenoma
Mucinous cystadenoma of the ovary is at the benign end of the spectrum of mucin-containing epithelial ovarian tumours. Epidemiology The estimated peak incidence is at around 30-50 years of age. They comprise approximately 80% of mucinous ovarian tumours and 20-25% of all benign ovarian tumou...
Ovarian mucinous cystadenocarcinoma
Mucinous cystadenocarcinoma of the ovary is a rare malignant ovarian mucinous tumour. This type can account for 5-10% of all ovarian mucinous tumours. It is a type of ovarian epithelial tumour. Pathology Retrospective studies have suggested that many mucinous carcinomas initially diagnosed as...
Mature (cystic) ovarian teratoma
Ovarian dermoid cyst and mature cystic ovarian teratoma are terms often used interchangeably to refer to the most common ovarian neoplasm. These slow-growing tumours contain elements from multiple germ cell layers and are best assessed with ultrasound. Terminology Although they have very simi...
Ovarian thecomas are benign ovarian tumours of sex cord / stromal (mesenchymal) origin. They are thought to account for approximately 0.5-1% of all ovarian tumours. As ovarian thecomas secrete oestrogen, they are described as functional ovarian tumours. Epidemiology They typically present in o...
Ovarian Sertoli-Leydig cell tumour
Ovarian Sertoli-Leydig cell tumours (SLCT), also known as an ovarian androblastomas, are a subtype of ovarian sex cord-stromal tumour. Epidemiology They are rare and only account for ~0.5% of all ovarian tumours. While they can present at any age, they typically present <30 years old, with a m...
Sclerosing stromal tumour of the ovary
Sclerosing stromal tumour (SST) of the ovary is a rare ovarian neoplasm. It is considered a subtype of ovarian sex cord / stromal tumour and is included in the fibroma-thecoma group of ovarian tumors 9. Epidemiology It occurs predominantly in young women, peaks around 2nd to 3rd decades of lif...
Pyosalpinx refers to a Fallopian tube that is filled, and often distended, with pus. Pathology A pyosalpinx often tends to be a complication of background pelvic inflammatory disease (PID). Inflammation results in tubal and peritubal adhesions with superimposed obstruction of the fimbrial end....
