Normal postmortem changes could mask underlying pathology This patient had a clinical history of allogeneic stem cell transplantation due to multiple myeloma. Clinical examination and antemortem MRI of the brain suggested a post-transplant lymphoproliferative disorder (PTLD). Autopsy diagnosed bronchopneumonia (left upper lobe and right lower lobe) as the cause of death and did not show PTLD, nor recurrence of multiple myeloma or other malignancy. PMCT showed pleural fluid and interstitial pulmonary oedema, which were interpreted as normal postmortem findings. Bronchopneumonia was not diagnosed at PMCT. PMCT, postmortem CT.
