Clinical Pearls from JCEM Case Reports: Pituitary Edition-Case Discussion: A False Pituitary Tumor

Video Transcription

Video Summary

In this webinar, Dr. Daniela Hurtado presents a case report titled "A False Pituitary Tumor." The patient, a 24-year-old male, was referred to Mayo Clinic for evaluation of progressively worsening headaches. The patient had a history of headaches for at least five years, which was accompanied by visual disturbances and other symptoms. MRI imaging showed a pituitary tumor, but further evaluation revealed findings consistent with intracranial hypotension, including downward shift of the mammillary bodies and dilation of dural venous sinuses. Laboratory tests showed no hormonal abnormalities. It was suspected that the patient had cerebrospinal fluid (CSF) volume depletion syndrome due to a CSF leak, which was confirmed by further imaging. The patient underwent a dynamic CT myelogram for localization and repair of the CSF leak, which successfully resolved the headaches. The key takeaways from this case include considering a false pituitary tumor in patients with pituitary enlargement without a hypo-enhancing lesion and imaging findings of intracranial hypotension, as well as the importance of reviewing past medical and surgical history in suspected CSF leak cases.
