Con formaciones aneurismáticas en arterias viscerales, especialmente en ramas de arteria mesentérica superior.  Caso clínico:  hombre de 44 años, acude por epigastralgia, náuseas y hematoquecia, presentando petequias en tronco, abdomen y miembros pélvicos. Leucocitosis de predominio neutrofílico, marcadores inmunológicos (ANCA) negativos. En angiotomografía abdominal se observan saculaciones en vasos ileales superiores.  Conclusión:  la PAN es una enfermedad vascular multisistémica poco común, con predilección por vasos de mediano calibre. Es importante identificar los signos radiológicos, ya que un retraso diagnóstico conlleva complicaciones como isquemia intestinal, roturas aneurismáticas u otras.]]></p></abstract>

With aneurysmal formations in visceral arteries, especially in superior mesenteric artery branches.  Case report:  a 44-year-old male with abdominal pain in the epigastrium, nausea, and hematochezia, presenting petechiae on the trunk, abdomen, and pelvic limbs, predominantly with neutrophilic leukocytosis, negative immunological markers (ANCA). In abdominal angiotomography, sacculations are observed in superior ileal vessels.  Conclusion:  PAN is a rare multisystem vascular disease with a predilection for medium-caliber vessels. It is essential to identify radiological signs since a diagnostic delay leads to complications such as intestinal ischemia, aneurysmal ruptures, and others.]]></p></abstract>
