Autopsy diagnosis of acupuncture-induced bilateral tension pneumothorax using whole-body postmortem computed tomography: A case report

Abstract

Rationale: Acupuncture, a component of traditional Chinese medicine, is also a well-known form of complementary and alternative medicine. Serious adverse events of acupuncture have been reported, including the acupuncture-related pneumothorax which is a rare but fatal condition sometimes. The pneumothorax was related to needle insertion in the upper back or paraspinal area and the reported victims suffered from either unilateral or bilateral pneumothorax. Postmortem computed tomography has advantages in the detection of pathologic gas and is being considered as a useful visualization tool for diagnosing the cause of death. Patient concerns: A 52-year-old man underwent acupuncture and cupping treatment at an illegal Chinese medicine clinic for neck and back discomfort and was admitted to the hospital with severe gasp and dyspnea about 30hours later. The patient suddenly became unconscious with heart rate and blood pressure lost and died after cardiopulmonary resuscitation. Diagnosis, interventions and outcomes: Whole-body postmortem computed tomography of the victim revealed collapse of the both lungs and mediastinal compression, which was also confirmed by autopsy. More than 20 pinprick injuries were found on the skin of the upper and lower back in which multiple pinpricks were located on the body surface projection of the lungs. The cause of death was concluded as acute respiratory and circulatory failure due to acupuncture-induced bilateral tension pneumothorax. Lessons: Acupuncture-induced tension pneumothorax is rare and should be recognized by forensic pathologists. Postmortem computed tomography can be used to detect and accurately evaluate the severity of pneumothorax before autopsy and can play a supporting role in determining the cause of death.
