Disseminated Mucormycosis and T-Cell-Depleted Allogeneic Stem Cell Transplantation: An Unusual Case Study.

INTRODUCTION

Invasive fungal infections are a primary cause of morbidity and mortality in patients with haematological malignancies.

CASE PRESENTATION: We describe an unusual clinical and radiological presentation of invasive mucormycosis (IM) in a 69-year-old patient with relapsed acute myeloid leukaemia. The patient was diagnosed with disseminated IM with involvement of the central nervous system in an atypical location, lung, spleen, muscle, bone, and heart, after having completed induction and bridging chemotherapy to allogeneic haematopoietic stem cell transplant (HSCT). Her clinical presentation was atypical with mild neurological symptoms slowly progressing over 2 months and without appropriate signs of systemic inflammation. Mucorales was eventually confirmed from bronchoalveolar lavage and subdural collection.

CONCLUSION

This report highlights the difficult challenges of managing disseminated IM in an immunocompromised patient, where close multidisciplinary specialist care enabled successful treatment, followed by T-cell-depleted allogeneic HSCT for a high-risk haematological malignancy.
