Angiography Revealing a Possible Paraneoplastic Vasculitis: A Case Report

Area of Science:

• Internal Medicine
• Oncology
• Rheumatology

Background:

• Vasculitis encompasses various conditions affecting blood vessels, classified by size (small, medium, large) and etiology (radiation-induced, systemic, paraneoplastic).
• Paraneoplastic vasculitis represents a small but significant subset (2-5%) of vasculitis cases, often less understood than other forms.

Observation:

• A female patient with a history of breast cancer presented with an upper gastrointestinal tract bleed.
• Diagnostic workup revealed an underlying diagnosis of systemic vasculitis, with a strong suspicion of a paraneoplastic origin.

Findings:

• The case illustrates a rare presentation of systemic vasculitis potentially linked to a prior malignancy.
• Imaging modalities played a key role in identifying vasculitis as the cause of the gastrointestinal hemorrhage.

Implications:

• This case underscores the importance of considering paraneoplastic vasculitis in cancer patients experiencing unexplained gastrointestinal bleeding.
• Enhanced diagnostic imaging is vital for uncovering vasculitis as an etiology for gastrointestinal bleeds in at-risk populations.
