Fatal idiopathic pulmonary haemosiderosis in association with pregnancy – Medico-legal evaluation

Abstract

Idiopathic pulmonary haemosiderosis is a rare disorder characterised by repeated episodes of intra-alveolar bleeding in association with consecutive anaemia, pulmonary fibrosis, pulmonary hypertension and respiratory failure. Pregnancy may exacerbate the symptoms of idiopathic pulmonary haemosiderosis typically worsening in the third trimester. A 32-year-old female after delivery was admitted to hospital with progressive dyspnoea of about 1-month duration. Sudden circulatory collapse caused fatal complication. During the post-mortem investigation, lung haemorrhage and histologically abundant iron deposition in macrophages and interstitial fibrosis were found. Medico-legal post-mortem evaluation of fatal cases may support the clinico-pathological context of the diagnosis of this entity.
