Subarachnoid Hemorrhage With Multifocal Cerebral Aneurysms in a Patient With Crohn’s Disease and Sjögren's Syndrome: A Case Report and Literature Review

Only a few reports of the association between Crohn’s disease (CD) and Sjögren's syndrome (SS) have been documented in the medical literature. Herein, we are presenting a 61-year-old female patient who presented with subarachnoid hemorrhage (SAH). She has a past medical history of primary SS on no active treatment, and CD in remission while on maintenance immunotherapy. She also tested positive for COVID-19. Computed tomography angiography (CTA) brain as well as cerebral angiogram revealed multifocal cerebral aneurysms. Successful coiling was achieved with a cerebral angiogram. This case serves to add to a limited body of reported cases and remind clinicians of the association between SS/CD and cerebral aneurysms. Herein, we review the literature regarding this association and also the effect of immunotherapy and COVID-19 on the progression of cerebral aneurysms.
