Symptomatic intracranial hypertension during recovery from the syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis (HANDL)

摘要

The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis (HANDL) is rare; it comprises migrainous headaches (generally in headache-naTve people), fluctuating neurological symptoms and cerebrospinal fluid (CSF) lymphocytosis. The syndrome generally runs a benign, self-limiting course over weeks. A small proportion of patients develop intracranial hypertension as a consequence of the illness. Recurrence of headaches or development of visual symptoms following apparent recovery from HANDL should prompt urgent re-evaluation for elevated intracranial pressure. Short-to-medium term management with CSF drainage and acetazolamide may be necessary to prevent visual loss.
