Practical Ultrasonography Uterine Calcification Fibroid Calcification Hypoplastic Uterus Case 1 Uterine calcifications. The most common cause of dense echoes in the uterus are calcifications resulting from fibroids. A less common cause of calcification within the uterus is that of the arcuate artery. Arcuate artery calcifications are seen around the periphery of the uterus, usually in older women with severe medical problems such as diabetes, chronic renal failure, or hypertension. Punctate calcifications occasionally are seen at the endometrial myometrial interface These are probably secondary to a prior infection or procedure. Case 2 Fibroid Calcification Case 3 Hypoplastic Uterus Hypoplastic uterus Fifteen years girl not menstruating, abdominal ultrasonography has done Secondary sexual characteristics are usually present, suggesting that normal ovarian activity may also be present. Simple hypoplasia: form of the uterus is normal, but is small in size. Elongated hypoplasia: fundus is normal, but the length is normal or more than normal. Hypoplasia of the uterus is usually indicated if the distance between the cornu or intercrual is less than 2 cm or if the distance from the internal os to the fundus is less than 3 to 5 cm. Endometrial thickness, endometrial cavity area, and endometrial cavity length markedly reduced. Markedly reduced cervical length may be noted Vagina present
