[IgG4-related disease that presented cranial, cervical, lumbar and sacral hypertrophic pachymeningitis associated with infundibulo-hypophysitis].

We report a patient of 32-year-old female with central IgG4-related disease. She developed headache and visual disturbance. On examination, she revealed diabetes insipidus, retrobulbar neuritis, hyperreflexia and limb weakness.

Reversible brain atrophy in anti-NMDA receptor encephalitis: a long-term observational study.

The long-term neuroimaging correlates of clinical recovery have not been described in anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. The aim of the study is to evaluate the long-term outcome of brain atrophy in anti-NMDAR encephalitis. Patients were two women (ages 17 and 33 years) with severe anti-NMDAR encephalitis resulting in decreased level of consciousness, autonomic instability, hypoventilation, and dyskinesias requiring continuous infusion of anesthetic agents for 6-7 months.

Regional cerebral blood flow and cerebrovascular reactivity during chronic stage of stroke-like episodes in MELAS -- implication of neurovascular cellular mechanism.

Background: Ischemic vascular hypothesis as a causative role in the pathogenesis of stroke-like episodes in MELAS remains to be debated.

Methods: This study consisted of two parts. Part 1 is a clinicoradiological study during acute stage of 18 consecutive stroke-like episodes in six patients with MELAS.
