“…A total of 87 arterial aneurysms in patients presenting osteochondroma were identified from 1963 to 2021. Patients were predominantly male (70.1%), with a mean age of 21.8 ± 11.5 years but ranging from 8 4 to 48 5 years old, and we described the case of the youngest patient in the literature having a pseudoaneurysm in osteochondroma, according to our results.…”

“…A regular postoperative course with neither complications nor recurrence was described in all cases during follow-up, which was reported to be up to five years. 5 Preventive treatment of asymptomatic forms is discussed. 32 Vascular examination and monitoring by Doppler ultrasound have been mentioned by some authors, but most authors recommend preventive removal of a solitary exostosis when adjacent to neurovascular structures, especially in the femoro-popliteal junction.…”

Popliteal artery pseudoaneurysms in patients affected by osteochondroma

Although exostosis or osteochondroma is a common bone tumor, associated vascular complications are rare. Clinical and radiological diagnoses are sometimes challenging, and there is no codification for surgical management. We report two cases of popliteal arterial pseudoaneurysms due to osteochondroma of the distal femur. A review of the current literature about case series and case reports of patients affected by arterial pseudoaneurysm complicating osteochondroma was also performed.

“…The constant pressure and pulsatile friction within the popliteal artery cause damage to the arterial wall. 2 The incidence of pseudoaneurysms has been reported as 0.6%–4.8%, developing primarily from access-related evaluations including catheter-based procedures. The reported incidence is varied based on the method of evaluation (clinical vs routine ultrasonography).…”

Popliteal artery aneurysms may be divided into true and false aneurysms (pseudoaneurysms). We present a case of a right popliteal pseudoaneurysm. A 67-year-old male presented to the hospital with significant pain in the right calf. A peripheral angiogram revealed extensive stent thrombosis in the right lower extremity. A thrombectomy and balloon angioplasty were done to reestablish blood flow. 2 weeks later the patient presented after a driving trip, with a peripheral angiogram revealing a popliteal pseudoaneurysm. Vascular intervention was performed, replacing the right popliteal artery with a 6 mm polytetrafluoroethylene graft. There is a high degree of suspicion for mechanical stress injury from prolonged knee flexion. The etiology of the pseudoaneurysm was most likely from mechanical stress, despite its historical association with true aneurysms. Although differentiating between true and false aneurysms is important in determining etiology, these are not all-inclusive and overlap of causation may occur.

“…Osteochondromas are typically benign and have been known to undergo spontaneous shrinkage [ 7 ], although the benign nature is not always the case as osteochondromas can undergo a malignant transformation in up to 1% of solitary lesions and up to 3% in patients with multiple lesions [ 1 ]. When left alone, osteochondromas can grow large enough to impinge on important vessels leading to vascular complications [ 8 , 9 ]. These complications demonstrate the importance of recognizing osteochondromas in clinically silent patients and those with atypical locations.…”

Introduction. Osteochondromas represent one of the most common bone tumors accounting for 8% of all bone tumors. While most osteochondromas arise in the metaphysis of long bones, osteochondromas have been reported in atypical locations such as the scapula, metatarsals, and the pelvic region. Osteochondromas are capable of growing large enough to cause mass effects and can undergo malignant transformation, stressing the clinical importance of recognizing these tumors. Case Presentation. In this case, we present an 18-year-old skeletally mature Caucasian male with a symptomatic osteochondroma arising from the iliac wing. The osteochondroma increased in size since he reached skeletal maturity. This resulted in a mass effect that interfered with activities of daily living, including clothing wear and symptomatic impaction on hard surfaces. Conclusion. The majority of osteochondromas arise from the metaphysis of long bones, but case reports have shown that osteochondromas presenting in atypical locations such as the pelvis do occur. In the case of our patient, his asymptomatic pelvic tumor grew to the extent that it was causing interference with activities of daily living. Surgical excision of his tumor proved to be curative, and there was no recurrence at 6 months after excision. Osteochondromas in this region are capable of growing large enough to cause sexual dysfunction. Clinical suspicion must be high to properly diagnose osteochondromas in atypical locations. All providers, particularly those in primary care, should be aware of these locations as patients with symptomatic mass lesions will likely initially present here.
