Patient: Description of condition (onset, main symptoms, hospital visited, etc.): MRI revealed a 2 mm RATHKES cyst in the pituitary gland along with eye blurring and transient inflexibility. Sometimes headache. Prolactin was high. Thirteen years ago had a brainstem hemangioma malformation underwent gamma knife five years ago hydrocephalus drainage analysis and got relief. Patient: Hello I just sent a message, I am a female patient. Zhang Nan: Eye blurring and transient inflexibility are not directly related to the possible presence of cysts in the saddle area. Whether it is related to the brainstem lesion needs to be specifically analyzed in the context of imaging and history of gamma knife treatment. Female patients with congenital rathke cysts can have hyperprolactinemia and can be treated with bromocriptine under the guidance of endocrinology. The dosage of the drug is adjusted with follow-up blood endocrine indicators. Current two millimeter lesions do not require surgery or gamma knife treatment.
