renal/urinary system

kidney cyst ( J:37799 , J:59839 )

nervous system

obstructive hydrocephaly ( J:37799 )

dilated fourth ventricle ( J:37799 )

• at 7 months of age the lateral, third, and fourth ventricles and cerebral aqueduct are dilated

dilated lateral ventricle ( J:37799 )

• at 7 months of age the lateral, third, and fourth ventricles and cerebral aqueduct are dilated

abnormal choroid plexus morphology ( J:37799 )

• at 7 months of age the lateral, third, and fourth ventricles and cerebral aqueduct are dilated

abnormal cerebral aqueduct morphology ( J:37799 )

abnormal olfactory bulb morphology ( J:37799 )

• most of the olfactory glomerular and external granular layers are absent, and in places are replaced by lacy vacuolated tissue

small olfactory bulb ( J:37799 )
