A seven‐year‐old boy presented to the neuropediatric clinic with right‐sided ptosis, external ophthalmoplegia, and mental retardation. Orbital magnetic resonance imaging (MRI) revealed anomalous soft tissue within the intraconal region, which was interpreted as an atavistic retractor bulbi muscle. In patients with external ophthalmoplegia and ptosis, anatomic variations observed in MRI should be given due consideration. In fact, knowledge about rare anatomical anomalies may contribute to a more accurate diagnosis of such ocular symptoms. Clin. Anat. 24:948–949, 2011. © 2011 Wiley Periodicals, Inc.
