It ruled Aubameyang out of Friday's game against Ghana and put the rest of his African Cup in doubt.
The "cardiac lesions'' were found in a check by Confederation of African Football medical officials, who examined Aubameyang to ensure he was OK to play again after he returned from a positive virus test, the Gabon federation said in a statement.
Two other Gabon players were also prevented from playing after similar medical checks following their return from positive virus tests.
The Gabon federation said Aubameyang's diagnosis wasn't serious but the medical officials ``did not want to take any risks,'' and CAF's medical commission ruled Aubameyang was not able to play against Ghana. A lesion is damage or abnormal change to body tissue.
Aubameyang tested positive for the virus at an airport on arrival in Cameroon last week and was put into isolation. He also missed Gabon's first game, a 1-0 win over Comoros.
The Gabon captain has since tested negative for the virus and was out of isolation two days before the Ghana game and was expected to return to the team.
Gabon forward Axel Meye and midfielder Mario Lemina were the other two CAF prevented from playing against Ghana after they also had evidence of cardiac lesions, the Gabon federation said. They had also been isolating because of positive virus tests.
The news regarding Aubameyang and his teammates came on the same day it was announced that Bayern Munich defender Alphonso Davies has been sidelined with evidence of heart muscle inflammation after he contracted the virus.
At the African Cup, Gabon played against Ghana without two other players because of the virus. Defenders Sidney Obissa and Lloyd Palun tested positive on Wednesday in mandatory testing of the squad 48 hours ahead of its game, the latest cases in Gabon's outbreak.
Gabon coach Patrice Neveu also tested positive on Wednesday but returned a negative test later ahead of the Group C game and was allowed to take his place on the sidelines.
Gabon scored an 88th-minute equalizer to draw with Ghana 1-1 and give itself a chance of qualifying for the knockout stages.
