Images in Cardiovascular Medicine. Hypoplasia of the abdominal aorta and hypomelanosis of ito: 'pseudo-cauda equina' imaging.

摘要

A 4-year-old girl with hypomelanosis of Ito (HI) was referred to the cardiologist for an absence of pulses in the lower extremities. Medical history included hydro-cephalus treated with ventriculoperitoneal shunt and congenital glaucoma. She always remained asymptomatic. Physical examination showed upper-body hypertrophy and a repeatedly measured systolic pressure difference between the upper and lower extremities of 35 mm Hg. Contrast-enhanced multidetector cdmputed tomography (Figure 1) showed aortic hypoplasia immediately distal to the origin of renal arteries.
