Acute systemic gas embolism in these whales was reported together with enigmatic cystic liver lesions (CLL), characterized by intrahepatic encapsulated gasflled cysts, tentatively interpreted as “gas-bubble” lesions in various other cetacean species. Here we provide a pathologic reinterpretation of CLL in odontocetes. Among 1,200 cetaceans necropsied, CLL were only observed in four striped dolphins (Stenella coeruleoalba), with a low prevalence (2%, N= 179). Together, our data strongly suggest that CLL are the result of the combination of a preexisting or concomitant hepatic vascular disorder superimposed and exacerbated by gas bubbles, and clearly difer from acute systemic gas embolism in stranded beaked whales that is linked to MFAS. Budd-Chiari-like syndrome in dolphins is hypothesized based on the present pathologic fndings. Nonetheless, further researched is warranted to determine precise etiopathogenesis(es) and contributing factors for CLL in cetaceans.||URI:||http://hdl.handle.net/10553/122744||ISSN:||2045-2322||DOI:||10.1038/s41598-022-16947-0||Source:||34th Annual Conference of the European Cetacean Society (ECS 2023).
