A 2-year-old child was admitted with bilateral bronchopneumonia. Durin
g convalescence he sustained sudden respiratory arrest for which he re
quired ventilatory support. He had undergone cholecystectomy 1 month p
rior to the above episode. The pathological examination of the gall bl
adder mass had revealed the features of metachromatic leukodystrophy.
Gastro-oesophageal reflux, which is associated with this neurological
disorder, was suspected to be the cause of this sudden respiratory arr
est and its presence was confirmed by barium swallow examination.
