Presence of headache and headache types in patients with tumors of the sellar region-can surgery solve the problem? Results of a prospective single center study

PurposeHeadache is a common presenting feature of patients with pituitary adenomas and other tumors of the sellar region. However, at present, it still is unclear whether the headache is actually caused by the tumor. To explore whether there is a relation, we examined in detail the headache types, their relationship to the underlying pathology, and if the headache responded to neurosurgery in a prospective study design.MethodsOne hundred twelve patients with tumors of the sellar region scheduled for neurosurgery in a single center were analyzed for presence and quality of headache before surgery and at least 3 months after surgery. Patients received headache and depression self-rating inventories, presented on a handheld computer (PainDetect®). Clinical variables thought to impact on headache were analyzed in conjunction with the inventories.ResultsFifty-nine (53%) patients reported headache in the 3 months prior to neurosurgery, 49 (44%) had headache at the time of filling in the questionnaires. The four patients with pituitary apoplexy described thunderclap headache. In the other patients diverse headache types were encountered, most frequently migraine. Untreated gonadotroph deficiency was significantly associated with absence of headache, while none of the other clinical and morphological variables related to headache. Presence of headache and disability due to headache were not significantly reduced after surgery.ConclusionApart from pituitary apoplexy we detected no specific headache type in our patient group and no significant improvement of headache after neurosurgery. Headache alone constitutes neither a valid diagnostic marker for the presence of tumors of the sellar region nor a sufficient indication for tumor removal.
