Congenital Arterial Calcification; A Case Report

The case is a 16 days old female neonate with RDS after birth without significant finding on CXR, but in conventional CT (one centimeter thickness slices) we saw a complete ring of calcification in the course of aorta and pulmonary artery trunk including their valves. By extension of CT slices to abdomen and pel-vis, calcification was found in the abdominal aorta, SMA, renal and iliac arteries. Unfortunately, the neo-nate expired after 24 hours and during this period the following laboratory findings were the only available ones: Glucose=240, BUN=9, Ca=0.9, P=9.6(neonate3.9-7.7), Na=135, K=6.8, WBC=22300 (N=47 L=52). This patient was the first offspring of a rural couple and although we invited them to return to us for fur-ther investigations to detect probable inheritable dis-eases in their family, they did not come back. In a review of literature, we were not able to find a simi-lar case and this may be a unique one.
