Almost all of these autopsies were conducted as forensic autopsies.

HIV infection was identified in 52 of 143 patients selected from forensic autopsies.

The subjects were patients with risk factors for HIV infection in whom forensic autopsies were performed between 1997 and 1999.

Results: We present 11 cases of undiagnosed primary CNS tumors resulting in sudden death that were identified among 54 873 forensic autopsies.
