Dopamine Agonist Therapy Induced Fatal Pneumocephalus in Giant Prolactinoma. (PubMed, JCEM Case Rep)
Dopamine agonist (DA) cabergoline (0.25 mg twice weekly) was initiated, and serum prolactin levels reached 3941 ng/mL (SI: 171.3 nmol/L) after 2 doses...Our case and review of 7 published cases of DA-induced pneumocephalus highlights male predominance, median tumor size of 5.5 cm (range, 4-9.5 cm), and onset within 1 to 12 weeks of initiation of DA therapy. Hence, for giant prolactinomas after DA initiation, it is essential to recognize the symptom complex associated with this rare life-threatening complication, pneumocephalus, and offer emergency surgical intervention.
