Diagnosis & Treatment
The patient's findings were consistent with a hydropneumothorax. The patient was admitted and a chest drain was attempted. A large amount of fresh blood was aspirated. The patient gave no relevant history of trauma and a provisional diagnosis of spontaeous haemopneumothorax was made. The patient recovered well and all investigations were normal. He was discharged a few days later. He was seen two days later complaining of retrosternal sharp pain. An ecg taken showed ST elevation in all leads. A diagnosis of pericarditis secondary to the initial episode was made. His symptoms resolved after treatment with non-steroidal anti-inflammatory medication and he was discharged again.
