Cavum vergae is a cavity posterior to the septum pellucidum whose clinical significance has previously been unclear. Ten children are described who presented with neurologic findings and were found to have a cavum vergae or cavum vergae and cavum septum pellucidum by brain computed tomographic (CT) scan. Of the ten patients, five had delayed development, four had macrocephaly, two had learning disabilities, two had abnormal electroencephalograms, and one had Apert's syndrome. No cases of cavum vergae were found in 50 children who had brain CT scans for head trauma. These observations suggest that cavum vergae is a nonspecific brain CT scan finding that can be associated with neurologic abnormality. The results of magnetic resonance imaging of one patient with cavum vergae are also described.
