Abstract

OJEDA, Amalia et al. Mycotic aneurism for septic embolism in a pediatric patient with acute linfoblastic leukemia. rev.colomb.cancerol. [online]. 2019, vol.23, n.4, pp.158-162. ISSN 0123-9015.  https://doi.org/10.35509/01239015.119.

Pediatric aneurysms are rare and can be caused for damaging of the arterial wall secondary to an infection, forming a blind sacculation contiguous to its lumen called mycotic pseudoaneurysm. The majority of reported cases are from elderly patients with comorbidities. The most frequent involucre microorganisms are Staphylococcus spp, Salmonella spp, Streptococcus spp and rarely fungi.

We present the case of a 3-year-old boy, with a recent diagnosis of acute lymphoblastic leukemia of B precursors in remission, with a high risk of relapse due to incomplete treatment and a history of bacteremia due to Staphylococcus epidermidis and fungemia due to Candida tropicalis; with cardiac vegetations that produce liver, spleen, lung and brain embolism, in whom a partially thrombosed mycotic pseudoaneurysm of the common and external iliac artery is found. The early diagnosis of this entity is of vital importance because of the risk of rupture. Surgical management will depend on the location, size and associated complications.

Keywords : Aneurysm; False Aneurysm; Infected Iliac Aneurysm; Aneurysm, Ruptured.
