    A 40-year-old woman with early-onset hypertension was evaluated for renal artery stenosis using advanced imaging techniques.

  • 2

    Initial EID-CT angiography indicated intermediate-grade stenosis, but did not suggest multifocal fibromuscular dysplasia (FMD).

  • 3

    Follow-up UHR PCD-CT angiography revealed a thin intraluminal diaphragm causing significant luminal narrowing consistent with focal FMD.

  • 4

    The diagnosis of focal FMD raised concerns for potential renal function decline, prompting a multidisciplinary decision for intervention.

  • 5

    PCD-CT enhances diagnostic confidence in focal renal FMD, improving clinical decision-making in cases of renovascular hypertension.
