Neuroimaging findings in neurosyphilis.

We report two cases of neurosyphilis with atypical clinical presentations that were compounded by atypical neuroimaging findings. In the first case, MRI brain scan findings were felt to be compatible with mesial temporal sclerosis or herpes simplex encephalitis. The second patient presented with a clinical picture compatible with normal pressure hydrocephalus as well as some degree of ventricular enlargement and prominent periventricular white matter changes by MRI brain scan.

Neuroimaging of the complications of epilepsy surgery.

Background And Purpose: Stroke-like symptoms can be associated with the invasive evaluation and surgical resection of epileptic foci in patients with intractable epilepsy. Neurological deficits following surgical procedures for epilepsy are not uncommon, but most are relatively minor and transient. The authors investigated the neuroimaging patterns of cerebral tissue insults in patients suffering neurological deficits directly related to procedures performed to evaluate and treat intractable epilepsy.

Trancranial Doppler monitoring of response to therapy for meningovascular syphilis.

Meningovascular syphilis is now quite uncommon, but there have been increasing reports in patients immunocompromised with human immunodeficiency virus. The response of syphilis affecting the central nervous system to antibiotic therapy remains a challenge. This is an even greater challenge in patients who have underlying compromise of the immune system.
