A case report of aneurysmal subarachnoid hemorrhage in a Young with IgA: A mere co-existence?

INTRODUCTION AND IMPORTANCE: Aneurysmal Subarachnoid hemorrhage (SAH) can be associated with various other conditions like Polycystic kidney disease, Ehler Danlos syndrome, Co-arctation of the aorta, etc. CASE PRESENTATION: Here we have reported a 21-year young lady with IgA nephropathy and aneurysmal SAH managed successfully. CLINICAL FINDINGS AND INVESTIGATIONS: The patient was a known case of IgA nephropathy diagnosed 18 months back from a kidney biopsy. She came to the emergency with a headache and vomiting for 2 weeks. Her initial headache was the worst she has had experienced and then the headache was continuous and not relieved by medications. Then she underwent a noncontrast CT scan of the head which showed Subarachnoid hemorrhage (SAH). INTERVENTIONS AND OUTCOMES: Left pterional craniotomy and microsurgical clipping of left ICA aneurysm performed. The patient was discharged without deficits. RELEVANCE AND IMPACT: Aneurysmal Subarachnoid hemorrhage(SAH) can be due to histopathological changes to the vessels following IgA nephropathy. These correlations could be studied further or else it could be only a mere coincidence.
