Reported is a case of a 20-year old G2P1 (1001) Pregnancy Uterine 22 weeks age of gestation (AOG), who suffered three episodes of aneurysmal rupture over a period of almost 8 weeks, the last being fatal occurring on the 27th week AOG, despite aggressive antimicrobial treatment, insertion of ventriculo-peritoneal shunt and clinically improving neurologic status. The patient succumbed to subarachnoid hemorrhage resulting from the third aneurysmal rupture. Mycotic aneurysm is a serious and catastrophic clinical condition, more so in a pregnant patient wherein management options are limited in order to preserve pregnancy.

This report will discuss the first documented case in the Philippines of mycotic aneurysm in pregnancy secondary to a valvular heart disease, to increase awareness on such cases for timely diagnosis and management.
