4-year-old male with a prolonged seizure, history VPS. Intracranial VP shunt catheter tubing is intact. Catheter tubing traverses the right parietal lobe, through the atria of the right lateral ventricle, and terminates with tip in the body of a mildly dilated left lateral ventricle. No change in the position or course of the catheter compared to previous examination. The right lateral ventricle remains collapsed and unchanged from previous exam, and the left ventricle also appears grossly unchanged compared to most recent brain MRI allowing for differences in the two modalities. Significant brain volume loss consistent with periventricular leukomalacia as well as abnormal callosal thinning. There is no evidence of periventricular edema to suggest elevated ventricular pressures. There is no evidence of intracranial hemorrhage, mass, or edema. The bones of the calvaria are thin and there is triangulated appearance of the skull, consistent with mild trigonocephaly. The brain may be small for age, correlate clinically for microcephaly. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
