Klaudia, from Wałbrzych in southern Poland, had completed her undergraduate degree at home before moving to China to continue her studies.
She was hospitalised in Beijing in mid-April after developing a rare complication of an ovarian tumour – autoimmune encephalitis – followed by further complications including thrombosis.
A Polish military aircraft brought her home on Wednesday after a 14-hour flight, landing in Wrocław where she was transferred to the Fourth Military Clinical Hospital.
Her mother, who accompanied her on the journey, said Klaudia had coped well with the trip.
