Figure 1
Clinical photograph of a 5-year-old boy showing diffuse swelling in the left knee (white arrow). The patient presented with increasing swelling, locking, stiffness (range of motion 30°–100°) and intermittent pain in the left knee for the past 6 months
Figure 2
Figure 2
(a) Antero posterior and (b) lateral radiographs of the knee showing an intraarticular mineralized mass. The rest of the bone seemed uninvolved (white arrow)
Figure 3
Figure 3
A sagittal magnetic resonance imaging with proton density sequence (a) TR 3000, TE 13 showing an intraarticular mass (slight hyperintense to the muscle) in the intercondylar notch with a large effusion (white arrow). A coronal short tau inversion recovery sequence (b) TR 5680, TE 51 showing lobulation and heterogeneity in the mass

Figure 4
Because of the symptoms, imaging studies and size of the mass, the patient was indicated for open excisional biopsy (a) Intraoperative photograph showing a large osteochondromatous mass in the intercondylar notch with bony continuity with the rest of the femur (black arrow). (b) The mass measured about 3 × 3 × 2 cm and was reported as an osteochondroma on histology, confirming the diagnosis of Trevor's disease

Figure 5
(a) Antero-posterior and (b) lateral radiographs of the same knee after 7 years followup showing no residual mass, deformity or premature closure of growth plates. The patient was totally asymptomatic with full painless range of motion
