The prognostic utility of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) in adult T-cell leukemia/lymphoma (ATLL) remains unclear, particularly in patients with indolent subtypes and cutaneous involvement. This study aimed to evaluate the usefulness of FDG-PET in predicting clinical outcomes in patients with indolent ATLL presenting with skin lesions. We retrospectively reviewed indolent ATLL with cutaneous involvement who underwent <sup>18</sup>F-fluorodeoxyglucose positron emission tomography at our institute for initial disease staging between April 2007 and March 2022. The data obtained were compared with the findings of cutaneous involvement in ATLL. The effect of maximum standardized uptake value on progression-free survival was analyzed using the Kaplan–Meier method. Patients were divided into groups based on whether their maximum standardized uptake value was above or below the overall mean maximum standardized uptake value (2.18), and progression-free survival was compared between the groups. Forty-three patients with indolent ATLL were included. We divided the cutaneous involvement of ATLL into six subtypes according to a previously reported classification of eruption types: patch, plaque, multipapular, nodulotumoral, erythrodermic, and purpuric. A total of 18 of 43 patients (41.9%) had <sup>18</sup>F-fluorodeoxyglucose-positive cutaneous lesions. However, 25 patients showed no <sup>18</sup>F-fluorodeoxyglucose uptake in cutaneous lesions. There was a significant difference in the mean maximum standardized uptake value between the nodulotumoral and multipapular (p = 0.036), nodulotumoral and patch (p = 0.036). There was a statistically significant difference in progression-free survival between the maximum standardized uptake value ≥ 2.18 and < 2.18 groups (p = 0.020). These findings indicate that the maximum standardized uptake value in cutaneous lesions could determine the prognostic association of ATLL with cutaneous lesions. Careful follow-up is required for patients with a higher maximum standardized uptake value for cutaneous lesions.

Objective: Discriminating between hemorrhage and iodine extravasation can pose challenges in conventional computed tomography (CCT) images following preoperative embolization for meningioma. This study aimed to assess the efficacy of dual-energy computed tomography (DECT) in differentiating hemorrhage from iodine extravasation after preoperative embolization for meningioma. Methods: Twenty-one consecutive meningioma patients who underwent CCT before and DECT immediately after preoperative embolization were included in this study. Two independent observers conducted qualitative assessments on CCT and virtual noncontrast (VNC) images and iodine maps (IMs) to differentiate between hemorrhage and iodine extravasation. One observer recorded CT values of hemorrhage and iodine extravasation on CCT and VNC images. The ratio of maximum attenuation to minimum attenuation on VNC images was defined as the VNC ratio. Statistical analysis included Kappa (κ) statistics, unpaired t tests, and receiver operating characteristic (ROC) analysis. Results: Interobserver agreement for qualitative assessment was fair (κ = 0.231) for CCT alone and good (κ = 0.723) for CCT plus VNC imaging and IM. The addition of VNC imaging and IM to CCT improved differential confidence in 16 (76%) and 18 (86%) cases of the two observers, respectively, increasing the area under the receiver operating characteristic curve (AUROC) from 0.868 to 0.895 and 0.658 to 0.947, respectively. At a cutoff value of 1.527, the VNC ratio was significantly higher for hemorrhage than iodine extravasation (P < 0.05), with the highest diagnostic performance (AUROC, 1). Conclusions: DECT with VNC imaging and IM is useful for differentiating hemorrhage from iodine extravasation in meningiomas with preoperative embolization.
