Pulmonary sequestration associated with pulmonary hypoplasia and pleural effusion is very uncommon. Only three cases have been previously reported in the literature. We add one more case and describe its interesting clinical, radiological and pathological findings.
Of 25 cases of idiopathic pulmonary fibrosis, confirmed by open chest lung biopsy between January 1979 and July 1981, 5 patients had been taking amiodarone in doses less than 600 mg daily for 1 to 6 years. No lung disease had been observed in any patient before the administration of amiodarone, and other drugs, factors and diseases thought to play a role in the causation of pulmonary fibrosis were ruled out. Two patients died of respiratory insufficiency, and only 1 does not now suffer from serious sequelae. Review of a further 5 cases reported in the literature and the present data suggest a causal link between administration of amiodarone and pulmonary fibrosis, and tend to indicate a hypersensitivity mechanism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
