Abstract
•Pituitary metastasis is rare, and it is the least common intracranial site of metastases.•Majority of cases of pituitary metastasis the patient is known to have a primary malignancy.•The clinical presentation and radiological features of pituitary metastasis are not specific making diagnosis difficult.•Management may include endoscopic trans-sphenoidal resection, chemotherapy, radiotherapy and hormone replacement.•Definitive diagnosis can be achieved through surgical resection.
Pituitary metastasis is rare, and it is the least common site of intracranial metastases. It is mostly asymptomatic but can present with diabetes insipidus, headache, ophthalmoplegia, visual disturbance and anterior pituitary dysfunction and in majority of cases patients known to have a primary malignancy.
This study presents a 54-year-old male presented with a few months history of headache and drooping of both eyelids and after proper investigations and endoscopic resection of the sellar mass the diagnosis was confirmed to be pituitary metastasis of lung adenocarcinoma.
Diagnosis and management of pituitary metastases are complex and depend on many factors. Endoscopic surgical resection and debulking alleviates symptoms and provides the definitive diagnosis which has great importance in cases with clinical presentation that does not strongly point to pituitary metastasis to avoid unnecessary radiotherapy and chemotherapy when possible.
