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.

1,3,5,6) Others include biliary atresia, polysplenia, skeletal anomalies and renal tract anomalies.
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.

6) Patients are more likely to be symptomatic in the presence of other associated anomalies such as congenital heart disease, asplenia, polysplenia or inversion of the bowel.
The first is the embryonic/fetal, "early," or syndromic form, accounting for 10% to 20% of cases, which is associated with a high frequency of additional congenital malformations (including asplenia, polysplenia, cardiovascular defects, situs inversus, intestinal malrotation, small-intestinal atresia, anomalous choledochopancreatic ductal junction, and various positional abnormalities of the portal vein and hepatic artery), and is referred to as biliary atresia-splenic malformation (BASM) syndrome.
