Abdom Radiol (NY). 2021 Apr;46(4):1703-1717. doi: 10.1007/s00261-020-02788-w. Epub 2020 Oct 10.


Despite the extensive controversy and debate of penile girth augmentation, high demands for such procedures are increasing. Penile inflammation is not common sequel after penile filler augmentation, but when it occurs, it has serious complications that sometimes necessitate emergency surgical intervention. Imaging with a variety of modalities, including ultrasonography, magnetic resonance imaging, and ascending urethrogrphy plays a paramount role in the detection and assessment of these conditions. Inflammatory conditions after penile girth augmentation using injectable fillers are ranging from local granuloma to penile abscess formation or diffuse cellulitis that may extend to the scrotum, perineum or deep pelvic organs. Rapid diagnosis and evaluation of extensions are important to avoid associated morbidity and permanent deformity. Our purpose is to provide a practical review of relevant penile anatomy, imaging appearance and injection technique of different types of subcutaneous fillers used in penile girth augmentation, and inflammatory complications that may occur after these procedures. Brief descriptions of patient clinical information and imaging features of inflammatory complications will be included and correlated in actual cases.
