A pregnant woman in her early 30s, at 20 weeks of gestational age, presented with recurrent haemoptysis, pleuritic chest pain and a productive cough of 6 months duration. She underwent CT pulmonary angiogram which demonstrated right pulmonary sequestration and right-sided consolidation. Pre-existing pulmonary comorbidities such as chronic inflammation, structural abnormalities or weakened blood vessels within the lungs can encourage the growth of abnormal blood vessels. During pregnancy, these dynamics can be further aggravated by increasing cardiac output to promote blood flow to the placenta and increasing oxygen delivery to the developing foetus. These changes likely cause increased blood flow to the pulmonary sequestration, resulting in haemoptysis. The patient was treated conservatively for community-acquired pneumonia with a course of oral amoxicillin 500 mg three times a day for 5 days, and she is doing well on follow-up.
