Male patient, 17 years old, due to decreased binocular vision, swelling of the eyes more than 3 months to “sphenoid sinus occupy ” admitted to hospital. Physical examination: the general situation is good, conscious, big eyes ranging from pupil, light reflection sensitive. CT scan showed spheroidal clumps of high-density mass of the sphenoid bone, the sphenoid sinus showed bone growth within the expansion of slightly higher density mass, the mass see the dense honeycomb, mesh bone separation shadow, the lesions can be seen around the high-density hardening Ring (Figure 1). MRI showed sphenoid sinus about 6.2 cm × 4.3 cm size, clear tumor boundaries were mixed T1, slightly longer T2 signal, the internal signal is uneven, T1WI low-letter
