Calvarial thickening from chronic ventricular shunting

Case contributed by Dr Heba Abdelmonem


Chronic shunt with history of recent trauma.

Patient Data

Age: 30-35 years
Gender: Male

Moderate thickening of the skull vault subtle right parietal bone marrow edema may be related to trauma. Ectopically inserted VP shunt tip within the left parietal lobe. Dysgenesis of the corpus callosum (the genu and anterior part of the body are present but very thin; the remainder of the corpus callosum is not depicted). Marked pneumatization of both frontal sinuses. Absent septum pellucidum with abnormal configuration and fusion of both of lateral ventricles. Moderate prominence cortical sulci, both Sylvian fissures as well as extra-axial CSF spaces associated with abnormal altered signal of the periventricular white matter with multiple small scattered deep white matter high FLAIR signal foci.

Case Discussion

This case nicely demonstrates thick skull secondary to chronic VP shunting. The absence of septum pellucidum, fusion of both lateral ventricles as well as callosal dysgenesis may suggest Lobar holoprosencephaly.
