Primary adrenal lymphoma (PAL) is a particularly rare subset of malignant adrenal neoplasms, accounting for ∼1% of all non-Hodgkin's lymphomas. Reported outcomes of PAL, though limited, are dismal, with a 12-month survival rate of ∼20%. PAL is treated with polychemotherapy and early tissue diagnosis to allow initiation of chemotherapy is associated with improved outcomes. Early and accurate radiological diagnosis of PAL is therefore essential in improving outcomes through informing decisions to biopsy and thereby facilitating timely initiation of chemotherapy. To date, however, imaging features of PAL have not been conclusively defined, and a range of divergent imaging appearances have been reported. Cinematic rendering (CR) is a 3D post-processing technique that simulates the propagation and interaction of photons as they pass through the imaged volume. This results in the generation of more photorealistic images that may allow for more comprehensive visualization, description and interpretation of anatomical structures. This manuscript presents the first characterization of the various CR appearances of PAL in the reported literature and provides commentary on the clinical opportunities afforded by CR in the workup of these heterogenous tumors.
