Case Discussion

CT study is the modality of choice in the diagnosis of different types of hernia and is better at differentiating Spigelian hernia. Ultrasound examination can detect Spigelian hernia as well, and is preferred than CT to exclude strangulation and ischemia by color Doppler study. Also, a linear probe gives more details than a curvilinear probe in the diagnosis of Spigelian hernia as it is related to the musculoskeletal system.
