A pituitary abscess with one year follow-up after conservative treatment: A case report

Pituitary abscess (PA) is a rare intrasellar infectious disease presented in less than one percent of all cases of pituitary disease. We reported a case of a 58-year-old woman with a history of type 2 diabetes (T2DM) exhibited with headaches, nasal discharge, anosmia, diabetes insipidus and hypopituitarism due to PA, she was diagnosed based on clinical presentations, endocrine examination and MRI image features. She was treated with nasal wash and antibiotic therapy without surgical intervention. She has received hormone replacement therapy for one year and her condition has gradually become stabilized. Meanwhile, the lesion of MRI image didn't become serious after one year. Conservative treatment might be an option for the patients with PA, those rejected operation or in a stable condition.
