Scintiscans and computer assisted tomographic findings of herpesencephalitis
Clinical Nuclear Medicine
|January 1, 1979
Abstract:
The radionuclide, CAT and angiographic features of a case of herpes simplex encephalitis are present. A dramatic change in the abnormal perfusion and static concentration of tracer activity resulted following chemotherapy with Adenine arabinoside. The improvement seen on the dynamic and static scintiscans correlates closely with the patient's clinical course and CAT findings. The radionuclide perfusion study is of particular importance in documenting the diminished activity of the inflammatory process following therapy.

Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
