Elderly gentleman came to the ED because he was wandering around the neighborhood.  A bystandard called 911.  He was pleasantly confused, had a mental status consistent with dementia.  The only other pertinent physical exam finding was some erythema, cellulitic appearance to his ankle.  We obtained a tibia and fibula xray looking for gas in the setting of cellulitis and this is what we found:

The densities in the soft tissue of his legs are “Rice bodies.”  They are sometimes seen in systemic cysticercosis.  These bodies are calcified dead cysts from the organism Taenia Solium.  Typically this tapeworm is found in pork.  Taenia Solium is rare in the U.S., it is more prevalent in underdeveloped countries especially with a diet that has potential to include raw or undercooked pork.  This should also be on your differential with new onset seizures (1).

He also had rice bodies on head CT.  Possibly the cause of his dementia?
