Abstract

We present an autopsy case of a 46-day-old male infant with chromosome 22q11 deletion, which is considered the primary cause of several diseases, including DiGeorge syndrome and velocardiofacial syndrome. The patient had 2 notable congenital abnormalities: multiple dissecting pulmonary arterial aneurysms distributed in both lungs and multiple jejunal atresia with apple-peel deformity. The former, a very rare pathologic condition especially in infancy, was found incidentally at autopsy and was the primary cause of death. To our knowledge, neither of these lesions has been reported previously in a patient with chromosome 22q11 deletion.
