A 34-year-old man presented to us with severe pain along the buttocks on sitting. For the last 3 months, after an episode of conus myelitis, he had not been able to sit down and was forced to be working in a standing posture. The pain also appeared in the supine position and got ameliorated on lying on his sides. On examination, he had a normal buttock shape, urinary incontinence, saddle anesthesia, and 4/5 grade weakness in the hip extensors and abductors with an absent ankle jerk. Magnetic resonance imaging showed focal hyperintense signal changes in the conus medullaris and hyperintensities in bilateral obturator internus muscles and gluteal muscles with severe atrophy of the gluteus maximus.[1] The buttock pain was likely caused by the atrophy of the gluteal muscles as a consequence of which his ischial tuberosity had lost its highly effective cushion. Pelvic screening should be considered when the patients complain of buttock pain after the presence of conus–cauda lesions has been established [Figure 1].{Figure 1}
