Hospital Course:
The patient, a 73-year-old female, was admitted to our hospital with the complaint of coughing up blood. Her medical history included hypertension, high cholesterol, and atrioventricular block with an implanted dual chamber pacemaker. On examination in the emergency room, the patient's vital signs were stable, and laboratory test results were within normal limits. Imaging studies revealed a collapsed right lower lobe and a diaphragmatic hernia. Bronchoscopic examination demonstrated the presence of blood clots in the right inferior lobar bronchus. Two arterial embolizations were performed with the insertion of an endobronchial Watanabe spigot but failed to stop the bleeding, leading to a thoracoscopic right lower lobectomy. The surgical specimen was diagnosed with pulmonary tumorlets on a hypoplastic right lower lobe. The postoperative course was uneventful, and the patient was eventually discharged.
