## TL;DR

A rare case of moyamoya disease combined with a non-functional pituitary macroadenoma is reported, highlighting the need for better understanding and treatment strategies.

## Contribution

This case report presents a rare co-occurrence of moyamoya disease and a non-functional pituitary macroadenoma.

## Key findings

- A 55-year-old woman with moyamoya disease experienced a hemorrhagic stroke.
- She also had a non-functional pituitary macroadenoma, a rare combination.
- The case underscores the importance of recognizing complex neurological presentations.

## Abstract

Moyamoya disease (MMD) is a rare neurological condition characterized by brain blood vessel narrowing, leading to collateral vessel formation. Diagnosis typically involves cerebral angiography and magnetic resonance angiography (MRA), with surgical revascularization often providing superior outcomes.

Here, we present the case of a 55-year-old woman with hypertension, diabetes, and a history of ischemic stroke. She recently experienced a hemorrhagic stroke due to MMD, compounded by a non-functional pituitary macroadenoma.

Recognizing signs of a hemorrhagic stroke is crucial to prevent future occurrences and ensure optimal outcomes. However, our understanding of the connection between MMD and pituitary macroadenoma remains incomplete. Further research is essential to refine diagnostic techniques and treatment strategies. Through continued research and awareness, we can strive for improved outcomes and an enhanced quality of life for individuals affected by MMD and its complications.
