Polyneuropathy due to n-Hexane Intoxication – A Case Series

n -Hexane, a volatile organic chemical, is notorious for its neurotoxicity in occupational settings. We present four patients working in a needle manufacturing factory who presented with polyneuropathy after exposure to n -hexane by inhalation. Cerebrospinal fluid showed albuminocytological dissociation. Nerve conduction study (NCV) showed primary demyelination with secondary axonal polyneuropathy. Excluding the other possible causes, the diagnosis of n -hexane neuropathy was kept. Patients were managed with symptomatic treatment and showed marked improvement in 6-month follow-up.
