Pituitary cysts can be detected by pituitary imaging, and the normal human pituitary gland is about 1 to 5 millimeters, so a pituitary cyst of 1.5 centimeters is considered large. Pituitary cysts, also known as Lacke’s cysts, are similar to intra-saddle craniopharyngiomas and pituitary adenomas in terms of clinical manifestations. They may be caused by congenital abnormalities in the development of the pituitary gland, or they may be caused by head trauma that results in the formation of cysts from cellular necrosis, and when the cysts get bigger the patient will have headaches, dizziness, and visual disturbances, which can be detected by methods such as pituitary magnetic resonance imaging. Lacunar cysts can be treated with medications such as mannitol and bromocriptine to improve symptoms, or in severe cases, with neuroendoscopic transnasal pituitary cystectomy, transnasal pituitary resection, and other surgeries. Patients with Lacunar cysts should go to the hospital in time for consultation and treatment, follow the doctor’s instructions for regular review, take medication on time, have a reasonable diet, eat a light diet, and at the same time maintain a healthy lifestyle. To control the condition and improve the symptoms.
