CASTRO-CASTRO, J.; TORRE-EIRIZ, J.A.; PINZON-MILLAN, A.  and  PASTOR-ZAPATA, A.. Cabergoline-induced tension pneumocephalus in a patient with giant invasive prolactinoma: Case report. Neurocirugía [online]. 2011, vol.22, n.6, pp.558-561. ISSN 1130-1473.

Treatment of patients with prolactinomas consists primarily of dopamine agonists (DA). When these drugs reduce the size of invasive prolactinomas, the intra-and extra-cranial spaces may be communicated. Pneumocephalus and cerebrospinal fluid leakage have been reported. A 56 year old male was admitted to the emergency unit with an intracranial hypertension syndrome. He had been treated for 2 weeks with cabergoline after an invasive prolactinoma was discovered. Brain CT showed frontal interhemispheric pneumocephalus on the previous tumor. cavity, and bony defect on the sellar floor. Evacuation of pneumocephalus, reparation of cranial and meningeal defects and subtotal tumor removal were performed. The literature is reviewed looking for possible pathophysiological mechanism, prevention and treatment.

Keywords : Cabergoline; Cerebrospinal fluid leak; Pneumocephalus; Prolactinoma.
