Clinical case report of intractable paroxysmal sympathetic hyperactivity in TANGO2 deficiency disorder.

TANGO2 deficiency disorder (TDD) is a neurodegenerative disease characterized by a broad and variable spectrum of clinical manifestations, even among individuals sharing the same pathogenic variants. Here, we report a severely affected individual with TDD presenting with intractable paroxysmal sympathetic hyperactivity (PSH). While progressive brain atrophy has been observed in TDD, PSH has not been reported.

Magnetic resonance angiography evidence of vasospasm in children with suspected acute hemiplegic migraine.

Hemiplegic migraine is a rare subtype of migraine that is differentiated by motor weakness in the aura phase. The purpose of this case series was to examine the magnetic resonance angiogram findings of patients suffering from suspected acute hemiplegic migraine. This was a retrospective institutional board review protocol study of 8 patients.

A child with transient neurologic deficits and headache associated with cerebrospinal fluid pleocytosis.

We report a case of a 10-year-old girl who had several episodes of severe headache, altered consciousness, and temporary neurologic signs and symptoms within a 2-month period. Cerebrospinal fluid examination showed lymphocytic pleocytosis and increased protein. Extensive microbiologic investigation and neuroimaging studies were negative.
