the presence of multiple spleens or accessory spleens.

pol·y·sple·ni·a

(pol'ē-splē'nē-ă), [MIM*208530]
A condition in which splenic tissue is divided into nearly equal masses or totally absent; congenital heart disease and malposition and maldevelopment of abdominal organs are common; may be related to situs inversus. Most cases are sporadic, although some suggest autosomal recessive inheritance.
See also: bilateral left-sidedness.

pol·y·sple·ni·a

(pol'ē-splē'nē-ă)
A condition in which splenic tissue is divided into nearly equal masses; there are several small spleens; congenital heart disease and malposition and maldevelopment of abdominal organs are common; may be related to situs inversus. Most cases are sporadic, although some suggest autosomal recessive inheritance.

In our patient, left isomerism resulted in the presence of two left symmetrical bilobed lungs, polysplenia, a transverse liver (centrally positioned) and a left-sided stomach bubble (Figs 2-4).
In addition, left-sided polysplenia, abnormal symmetric bronchial branching pattern, and bilateral left atrial appendages were detected.

Anomalies which are according to the literature associated with Pentalogy of Cantrell are: agenesis 1 of the corpus callosum, hydrocephalus, anencephaly, lip and palate cleft, fusion of the adrenal gland with liver, colon malrotation, clinodactily [9, 10], the absence of tibia and radius, polysplenia, underdevelopment of the gallbladder [11].
IVC hypoplasia may also be associated with other congenital anomalies, such as polysplenia, renal or pulmonary dysgeneses, dextrocardia or other congenital cardiac diseases.
