Mucormycosis with pulmonary, renal, pancreatic and spleen involvement detected by 18F-FDG PET/CT in a patient who underwent allogeneic stem cell transplantation. Report of case

Mucormycosis is a rare life-threatening opportunistic infection caused by mycetes of the order Mucoraceae.It appears mainly in immunocompromised patients (hematologic malignancies, anemia, AIDS) and in cases of advanced diabetes.A delayed diagnosis may imply a worse prognosis, so an early detection is mandatory for an adequate treatment.Herein we present a rare case of multi-organ mucormycosis with pulmonary, renal, pancreatic and spleen involvement detected and assessed by 18 F-FDG PET/CT in a 24-years-old woman diagnosed of grey zone lymphoma (DLCBL/HL) who underwent an allogeneic stem cell transplantation.PET/CT with 18F-FDG was a key element in biopsy guide, final diagnosis and monitoring of response to therapy.
