Chordoma presenting as pseudoprolactinoma

Chordomas are relatively rare neoplasms that appear to originate from benign remnants of primitive notochord. They account for about 0.15% of all intracranial neoplasm and are the most common of extradural neoplasms that involve the clivus. Although they present mostly with signs and symptoms of other intracranial lesions they rarely present with high prolactin levels mimicking prolactinomas. We report a case of chordoma presenting as a pseudoprolactinoma. We discuss the presentation, radiological features and treatment of this rare presentation.
