The controversial Italian striker surprised reporters when he entered the conference room to greet the directors of his old club and welcome the new boss, who took over on Monday
The former Inter Primavera chief, who recently led his side to victory in the final of the NextGen Series, was appointed as successor to Claudio Ranieri as boss of the senior side on Monday.
During his first press conference as Nerazzurri supremo, the proceedings were interrupted when former player Balotelli entered the room.
The City striker greeted Stramaccioni and the Inter directors who were present before taking his leave once more.
The new boss was so stunned that he turned to a journalist after the 21-year-old had left and asked: “What was the last question?”
Stramaccioni is 4/1 with Sportingbet to be the Inter manager on the first day of the 2012-13 season.
The former Roma coach had earlier expressed his pride at realising a dream by taking the reins at struggling Inter, insisting that he was not scared to be the latest man to attempt to emulate the success of Jose Mourinho at San Siro.
"This is a dream for me, I'm proud to train these players,” he told reporters. "I'm not scared, our target is to restart winning since the match versus Genoa. I'm different from Jose Mourinho."
Balotelli quit Inter for the Etihad Stadium in the summer of 2010.
He has courted controversy ever since his arrival in England with a string of off-the-field antics, but has repaid the faith placed in him by manager Roberto Mancini with 15 goals to his name this season.
