RESUMO
Background: Respiratory failure secondary to bilateral diabetic phrenic neuropathy is an uncommon clinical scenario. It is challenging to treat and often results in the need for long-term respiratory support. Case Presentation: We report a patient with long standing diabetes mellitus (DM) who presented with respiratory failure requiring mechanical ventilation. He was subsequently found to have reduced phrenic nerve and diaphragm compound action potential amplitude bilaterally on nerve conduction studies. Conclusion: Diabetic patients with unexplained shortness of breath should raise suspicion for diaphragmatic paresis from phrenic neuropathy.
RESUMO
Pulmonary artery aneurysm (PAA) is defined as pulmonary artery diameter greater than 4 cm. With advances in cardiac imaging, the detection rate has increased but the natural history remains unknown. We present the case of a large, incidentally identified PAA in a patient with a history of congenital pulmonic stenosis.
