The uterus is divided into four anatomical parts. The fundus is the uppermost part and extends into the interstitial portion of the fallopian tubes laterally. The corpus is the main body of the uterus, and the isthmus is the lowermost portion, which extends into the cervix. The lower uterine segment in the pregnant uterus forms at the isthmus, which is at the level of the reflection of the urinary bladder in the non-pregnant uterus. Uterine fibroids are the most common uterine abnormality encountered in women of reproductive age. Ultrasound has the advantages of being a widely available outpatient imaging modality, with the ability to measure and assess the depth of fibroid involvement into the myometrium more accurately than any other imaging technique. Uterine sarcoma is a rare tumour of the uterine myometrium that is usually diagnosed after hysterectomy. The clinical presentation is enlarging uterus in a post-menopausal woman.
