RESUMEN
Inflammatory myofibroblastic tumor (IMT) is a very rare lesion of unknown etiology. Cases of IMT involving the appendix are exceptional, and they can mimic malignant appendicular tumors. We present a case of a 65-year-old man who presented to our emergency room on septic shock and acute abdomen secondary to visceral perforation. The patient underwent exploratory laparotomy; massive bowel dilatation was encountered, along with 3 L of purulent intraperitoneal fluid and a perforated appendicular mass of 6 cm. An appendicectomy was performed. Histopathologic examination established the diagnosis of inflammatory pseudotumor with appendiceal perforation. This study constitutes the 14th confirmed case report of an appendicular IMT. It is important to include IMT in differential diagnoses of appendicular masses to avoid excessive resections.
RESUMEN
Hepatic artery thrombosis is the most frequent vascular complication following orthotopic liver transplantation, and often results in biliary complications, early graft loss and death. Surgical revascularization and retransplantation are considered the mainstay of treatment. However, intraarterial endovascular therapy is an alternative that has shown low morbidity and mortality, thereby avoiding the need for retransplantation. We describe a case of orthotopic liver transplantation complicated with hepatic artery thrombosis that was successfully treated with endovascular therapy.
