Arcuate Uterus –  T2 Weighted MRI

The T2 weighted MRI in axial projection of a 31 year old female shows the endometrial cavity in coronal view with an arcuate shape. This is a normal variant and has no clinical significance. The follicles in the ovaries are also well demonstrated . CODE uterus endometrial cavity ovary ovaries follicles fx arcuate shape dx normal variant

This hysterosalpingogram is from a 26 year old female with normaL endometrial cavity and cervical canal. Note the irregular shape to the cervical canal while the endometrial lining is smooth. Note also the free spillage of contrast from the tubes into the peritoneal cavity (white contrast in d, indicating patent tubes. codefallopian tubes and fimbrae normal anatomy cervix uterus HSG hysterosalpingogram

Filling Defect at the Left Cornu

This 38 year old female presents with a history of infertility. The hysterosalpingogram shows non filling of both Fallopian tubes and a filling defect (green) in the region of the patient?s left cornu that likely is the cause of the obstructed left tube and in part the cause of the infertility. The lesion is most likely a submucosal fibroid.

Carcinoma of the Cervix in a Bicornuate Uterus Complicated by Obstruction

 74 year old female with bicornuate uterus and dilated endometrial cavities Diagnosis is carcinoma of the cervix with obstruction . The myometrium is overlaid in dark pink, and the endometrial cavity is a heterogeneous orange consisting of both fluid and soft tissue elements.

Fibroid Impingement on the Endometrium

In this sagittal view of a T2 weighted MRI of the uterus of a 42 year old female with multiple fibroids two of which impinge on the endometrial cavity (the larger (light green) from posterior and the smaller (dark green) from anterior resulting in a sigmoid shaped cavity (yellow). In addition incidentally noted Nabothian cysts (orange) are seen within the cervix.

Deformity of the Endometrial Cavity Caused by an Intramural Fibroid

In this sagittal view of the T1 weighted contrast enhanced study of the the uterus of a 46 year old female. The uterus roughly retains its pear shaped structure but the shape of the endometrial cavity is distinctly abnormal as if there is something pushing on it from above. This patient has a diffusely enhancing isointense leiomyoma that impinges on the endometrial cavity.

Large Intramural Fibroid Deforming the Stripe

T2 Weighted Image

In this sagittal view of the T2 weighted MRI of the uterus of a 46 year old female an almost 6cms slightly hyperintense fibroid is seen pushing on the endometrial cavity from above. This patient has a large fibroid aka leiomyoma that impinges on the endometrial cavity.

Bicornuate Uterus T2 Weighted Image

The series of images from a young adult female with Bicornuate uterus with agenesis of the left kidney.

Image a is a coronal T1 weighted contrast enhanced image that shows absence of the left kidney.

Image b is an ultrasound in transverse dimension that shows two endometrial cavities.

Image c is a T2 weighted image that shows 2 separate horns that fuse above a single cervix and overlaid in pink in image d

These findings are consistent with bicornuate uterus with agenesis of the left kidney.  Combined congenital anomalies of the uterus and renal system are a well known association.

Unicornuate Uterus with Subsequent Pregnancy

34 year old female who presented with infertility had a hysterosalpingogram which showed a unicornuate uterus (a). An MRI confirms the diagnosis using a T2 weighted sequence(b). The patient subsequently fell pregnant and was scanned with a normal 13 week pregnancy(c).
