Abstract: BACKGROUND: Endonasal endoscopic approach (EEA) has become an integral part of neurosurgery, particularly for managing various pathologies involving the sellar and parasellar region and removing lesion in that area. But there is a rare condition in this area that not so common in literature is pituitary abscess (PA) after EEA for pituitary adenoma. CASE DESCRIPTION: A healthy 57-year-old man presented with a recurrent of bitemporal hemianopsia, persistent hypoadrenocorticism. In the history, he underwent two times of endonasal endoscopic transphenoid to remove pituitary adenoma. Magnetic resonance imaging (MRI) showed a sphenoid and sellar lesion with suprasellar extension and compression of the optic chiasm, with homogenous signal inside. Endoscopic transphenoid surgery was performed and the lesion was found is an abscess inside sphenoid and sellar with frank pus was obtained. But culture of the fluid was negative. After the operation, the patient was treated with antibiotics. His symptoms resolved after EEA, he improved visual field at this time but still in hypoadrenocorticism condition. An MRI was obtained after the operation to reveal that the lesion in sphenoid and sellar totally removed. We report on a rare case of a PA after two times of endonasal endoscopic transphenoid surgery of pituitary adenoma, and discuss the management of these conditions. We report a patient that came with us with recurrent of bitemporal hemianopsia and persistent hypoadrenocorticism. The patient undergone endonasal endoscopic sphenoid two times in the past. He didn't have clinical signs of infection. Imaging feature on MRI was high T2 and also high on T1 with homogenous signal inside with size 3.2 cm × 3.2 cm. Another EEA for this patient was performed to remove abscess and obtain pus from the lesion, but the result of culture was negative. He improved visual field but still in hypoadrenocorticism. CONCLUSIONS: In this case we report on a rare complication of transphenoid surgery, a PA progresses after EEA for a pituitary tumor. With this clinical experience, the correct diagnosis of PA before surgery, so it is a key leading to an exactly treatment for this condition. endonasal endoscopic transphenoid approach to drainage and removing abscess, and using antibiotics are necessary to improve the outcome of PA.
