Abstract:
Polyarteritis nodosa (PAN) is characterized by multisystem necrotizing vasculitis, primarily affecting small-to-medium-sized muscular arteries, and it is typically found in middle-aged men. PAN is rarely found in the female genital tract (including the uterus), and imaging of the uterus with PAN has not previously been reported. Reported is a case of a 78-year-old patient with uterus enlargement who was diagnosed with PAN through clinical findings and images. Computed tomography and magnetic resonance imaging findings of a uterus affected by PAN are presented and reviewed, and potential characteristic findings of the uterine with PAN are discussed.
Insights
Polyarteritis nodosa (PAN), a rare condition affecting blood vessels, was diagnosed in a 78-year-old woman’s uterus. This case presents unique imaging findings for uterine PAN, previously unreported in medical literature.
Area of Science:
- Vascular Medicine
- Radiology
- Gynecologic Pathology
Background:
- Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis affecting small to medium muscular arteries, typically in middle-aged men.
- PAN rarely involves the female genital tract, with uterine involvement being exceptionally uncommon.
- Uterine imaging findings in PAN have not been previously documented in scientific literature.
Observation:
- A 78-year-old female patient presented with uterine enlargement.
- Diagnostic workup included computed tomography (CT) and magnetic resonance imaging (MRI).
- Clinical and imaging data led to the diagnosis of PAN affecting the uterus.
Findings:
- The study details the specific CT and MRI characteristics observed in the uterus affected by PAN.
- These imaging findings are analyzed in the context of known PAN pathology.
- Potential pathognomonic imaging features of uterine PAN are discussed.
Implications:
- This case expands the understanding of PAN's potential target organs.
- It highlights the importance of considering PAN in the differential diagnosis of uterine enlargement with specific imaging findings.
- The report provides a foundation for future research on imaging biomarkers for uterine PAN.
