Olfactory neuroblastoma with initial manifestations of hyponatremia: a case report / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

Clinical records of a patient with olfactory neuroblastoma presented with hyponatremia as initial symptoms were analyzed and the literatures were reviewed. At initial onset, the patient presented with hyponatremia. After pathological examination, the diagnosis was olfactory neuroblastoma. The blood sodium has been normal after operation and radiotherapy. The incidence rate of olfactory neuroblastoma is low, and it is easily misdiagnosed. Its diagnosis relies on pathological examination. We should pay more attention to the unspecific symptoms of patients with hyponatremia, which can help to improve early diagnosis and the prognosis.
