Objective: The objective of this study was to evaluate pretransplant sinus computed tomography (CT) as predictor of post-hematopoietic stem cell transplant sinusitis. Methods: We evaluated pretransplant and posttransplant CT findings in 100 children using the Lund-Mackay system and "common-practice" radiology reporting and correlated these with the presence of acute sinusitis. Results: Fourteen percent of patients with normal screening CT developed posttransplant sinusitis, comparedwith 23%with radiographic abnormalities and 22% with clinical sinusitis alone, not statistically significant. Sensitivity of CT findings for clinical sinusitis ranged between 19% and 56%. Except for mucosal thickening (71% specificity), other findings had high specificity between 92% and 97%, particularly when combined. Lund-Mackay score change of 10 or greater from baseline was associated with a 2.8-fold increased likelihood of having sinusitis (P < 0.001). Conclusions: Screening CT can serve as a baseline, with a Lund- Mackay score change of 10 or greater constituting a significant threshold. The strongest correlation with the presence of acute sinusitis was seen with combined CT findings.
