\section{Conclusion}
In this work, we have shed light on the issue that unsupervised lesion detection and Out-of-Distribution detection are by nature entangled since, by definition, the former relies on the latter. 
We point out that more work needs to be done to fully understand and solve the issue of entangled \ac{ood} factors to enable safe deployment of models performing unsupervised lesion detection, such as further analysis with other types of detection frameworks, i.e. restoration-based methods.
