Each week, Live Science highlights a fascinating medical case report in its Diagnostic Dilemma series. We explain the client and their signs, the screening and history-taking that exposed their medical diagnosis, their course of treatment and their supreme health results. We likewise highlight what makes the case distinct, whether it’s the rarity of the medical diagnosis, the uncommon constellation of signs, or an unique healing technique.
