Bernardo Provenzano, 78, of Palermo, has a "syndrome akin to Parkinson's disease" and recently suffered a restriction of blood flowing to the heart, an ischemia, the Italian news agency, ANSA reported Thursday.
Italian law allows convicts to be released to a medical facility or to house arrest if too sick to remain in prison, ANSA said.
Provenzano was captured in 2006 after 43 years on at large, and is serving a life sentence for crimes including the slayings in 1992 of two anti-Mafia heroes, ANSA reported.
Provenzano is in solitary confinement at a high security prison near Turin, ANSA said.
