1/4. athletes with lower limb ischaemia.

    The case of a young healthy sportsman and acute exacerbation of chronic infragenicular pain is presented. Further investigation revealed an obstruction of the tibiofibular trunk due to an osteochondroma, arising from the fibula, which was immediately resected. osteochondroma is observed in 1-2% of the population and may present with vascular complications. In young patients and athletes, leg pain may be of vascular origin due to an entrapment or compression and should always be considered.

2/4. Vascular compression caused by solitary osteochondroma: useful diagnostic methods of magnetic resonance angiography and Doppler ultrasonography.

    osteochondroma is a common benign bone tumor that sometimes causes vascular complications when the lesion is situated near the knee. Venous complications are seen less frequently. We report two cases of solitary osteochondroma that arose in the distal femur. The patients were an 11-year-old boy and a 16-year-old boy, both of whom were suffering from bone protuberance and lower leg swelling due to congestion. In both patients, magnetic resonance imaging (MRI) revealed dilated popliteal veins at a site distal from the tumors or superficial veins. MR angiography (MRA) showed compressed popliteal arteries, and Doppler ultrasonography revealed weaker blood flow in the dorsalis pedis arteries in the lower leg with the tumor than in the other lower leg. The former patient complained of pain due to swelling in the lower leg, and for this reason the patient underwent resection of the tumor. After resection, both the swelling and the pain were decreased, and Doppler ultrasonography also revealed normal blood flow in the artery. The latter patient had swelling, but no pain, in the lower leg, and accordingly this patient has been followed carefully without resection, since there is always the possibility of irreversible vascular damage caused by osteochondroma, such as arterial or venous occlusion. We present two patients with osteochondroma, both of whom suffered from swelling of the lower leg due to venous compression by the tumor. In both cases, MRI and MRA were useful to show the presence of vascular compression. Doppler ultrasonography could also reveal the blood flow disturbance objectively, even in current osteochondroma cases in which there were no arterial symptoms.

3/4. Pseudoaneurysm complicating osteochondromas: symptom relief with embolization.

    Pseudoaneurysm is a recognized vascular complication of osteochondromas. The diagnosis is confirmed by various imaging techniques including ultrasound, magnetic resonance imaging, and conventional angiography. Surgical repair and excision of the adjacent osteochondroma is considered the treatment of choice. The authors report a case of successful transarterial embolization using helical microcoils in the treatment of osteochondroma-related pseudoaneurysm of the superficial femoral artery. It resulted in complete obliteration of blood flow to the pseudoaneurysm and good symptomatic relief before subsequent semielective surgery. No complication was encountered during the procedure. Transarterial embolization is a safe mode of treatment in experienced hands. In patients with contraindications to surgery, embolization may be considered a definitive treatment.

4/4. Postraumatic popliteal pseudoaneurysm from femoral osteochondroma: case report and review of the literature.

    osteochondroma is the most frequent bone tumor and can be responsible for vascular complications. The case of an 14-year-old boy with a popliteal pseudoaneurysm after a blunt trauma is presented. The diagnosis and treatment of this condition is discussed, and the English-language literature is reviewed.
