these questions seem to come most usually from some one not satisfied 
with the official report and concerned that there may be causes that a 
more dilligent search might have revealed; is that the case ? perhaps you 
might get a more complete response if you posted the history and physical 
findings of the case involved.
From a general perspective there are numerous reasons for an autopsy not 
revealing a cause of death. These reasons often vary with the age and sex 
of the deceased.Were any premorbid conditions known? Was the death 
witnessed? Was the deceased in a hospital etc. etc.? Is there a family 
history of similar events?
