| Abstract: | Ground glass attenuation (GGA) of the lungs is a common finding of post-mortem computed tomography (PMCT) that is associated with pulmonary congestion and edema due to cardiac failure during the agonal period, or due to post-mortem hypostasis. However, hypo-attenuation of the lung is an atypical finding of PMCT, and is usually a consequence of hypovolemic states before death or postmortem body posture after death. Previous studies have shown a few differential diagnoses, such as hypothermia, massive hemorrhage, asphyxiation by hanging, and dehydration, for hypo-attenuation of the lung. This report presents the case of a woman who died suddenly because of an asthma attack. Our PMCT analysis demonstrated hypoattenuation of the lung in this case. We suggest fatal asthma as a differential diagnosis for the appearance of hypo-attenuation of lungs on PMCT. |
