Media mogul and Turner Broadcasting System founder Ted Turner has been hospitalized in South America for an undisclosed condition.

Turner’s spokesman, Philip Evans, told The Atlanta Journal-Constitution that Turner was admitted to a South American hospital for observation, but did not disclose a location or Turner’s condition.

A South American newspaper reported online that Turner was traveling in the Patagonia region of Argentina. According to the Buenos Aires Herald, Turner was hospitalized in the southern city of Bariloche with appendicitis. The Herald reported he refused surgery at a first hospital and opted to travel to Buenos Aires. The report could not be immediately confirmed. Evans declined to comment on the Herald’s report.

According to the Associated Press, Turner was first treated earlier Friday at the San Carlos Sanatorium in Bariloche, near his ranch in the Patagonia region. A spokeswoman who gave her name only as Marina told the AP that Turner left that clinic after about four hours.

Early Friday afternoon, the Associated Press reported that a security guard at the Instituto Argentino de Diagnostico y Tratamiento had confirmed Turner was hospitalized there. Speaking on condition of anonymity because of hospital policy, he said the institute’s director told him that Turner’s companions had asked that no information be released about his condition.

The 75-year-old billionaire founded CNN and formerly owned the Atlanta Braves, Hawks and Thrashers.
