1/18. Pseudoaneurysm of the popliteal artery caused by exostosis of the femur: case report and review of the literature.A 13-year-old boy with a solitary exostosis of the left femur was seen with a pseudo-aneurysm of the popliteal artery. When left leg pain occurred 3 months earlier, radiographic examination revealed an exostosis with a cartilage cap. Serial radiographic examination demonstrated gradual disruption of the cartilage cap of the exostosis as the pseudoaneurysm developed. An exostosis with an irregular surface was found at surgery. A literature review disclosed 39 similar cases in which loss of the cartilage cap was considered as one of the causes of the aneurysm formation. Considering the clinical course of our patient, however, we believe that exostoses lose their cartilage caps by pressure destruction due to the aneurysms. It is highly probable that loss of the cartilage does not cause the aneurysms.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
2/18. Telangiectatic dedifferentiation of a parosteal osteosarcoma.A unique case of parosteal osteosarcoma (POS) of the proximal femur, with areas of telangiectatic dedifferentiation, in a 28-year-old woman is reported. The patient had a 7-week history of pain and swelling in her right thigh. A biopsy diagnosis of POS was established. The patient was treated with two cycles of intraarterial chemotherapy, followed by limb salvage surgery. Histological examination of the resected specimen showed POS with areas of dedifferentiation composed of highgrade telangiectatic osteosarcoma with associated secondary aneurysmal bone cyst change.- - - - - - - - - - ranking = 0.0033185627410597keywords = aneurysm (Clic here for more details about this article) |
3/18. osteochondroma as a causal agent in popliteal artery pseudoaneurysms: case report and literature review.Osteochondromas are an infrequent, but significant, source of vascular injuries. popliteal artery pseudoaneurysms are the most common sequelae, with a complex interplay of anatomic and developmental factors accounting for their prevalence. The authors present a case report, detailed discussion, and literature review of pseudoaneurysm formation in the popliteal artery.- - - - - - - - - - ranking = 5.8407089884291keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
4/18. 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.- - - - - - - - - - ranking = 1.9634958098483keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
5/18. 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.- - - - - - - - - - ranking = 4.8672574903576keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
6/18. Case report 748: chondroblastoma of the femur with an aneurysmal bone cyst.A case of chondroblastoma associated with an aneurysmal bone cyst has been described. The radiographic appearance of the lesion understandably reflects the combined features of both tumors. Up to one-half of all cases of aneurysmal bone cysts are found in association with other tumors, benign or malignant, and up to 15% of chondroblastomas are combined with an aneurysmal bone cyst (4).- - - - - - - - - - ranking = 0.023229939187418keywords = aneurysm (Clic here for more details about this article) |
7/18. Clear cell chondrosarcoma of the proximal femur with intrapelvic extension.Clear cell chondrosarcoma is a rare tumor that can be easily confused with benign tumors. The aim of this report is to present a case that is rare, initially diagnosed as aneurysmal bone cyst and then chondroblastoma, and has an interesting extension pattern. A 41-year-old male patient was treated for an apparently benign cystic lesion of the right proximal femur by intralesional excision and bone grafting. The pathological diagnosis was aneurysmal bone cyst. Two years later, the patient presented with a pathological fracture at the same site and a total hip arthroplasty was performed. The pathological specimen was diagnosed as chondroblastoma. Three years later, clinical and radiological examination of the patient revealed a large mass located on the intrapelvic side of the acetabulum. There was no evidence of distant metastases. Both tumors were resected with a wide margin on the femoral side and a marginal margin on the intrapelvic side. The extremity was reconstructed with a resection-type total hip prosthesis. Again, the pathological diagnosis was chondroblastoma. The patient developed a deep infection that was treated by antibiotic therapy and surgical debridement. One year later, there was recurrence of the femoral and intrapelvic masses and right hemipelvectomy was performed; the specimen was reported as clear cell chondrosarcoma. Since then, the patient has been leading an active life, and there is no evidence of local recurrence or distant metastasis. Clinically and pathologically, clear cell chondrosarcoma may be confused with benign bone tumors. This caused a delay in the final diagnosis of this patient and he received inadequate surgical treatment, leading to a hemipelvectomy. We also found that the intrapelvic mass seemed to have developed independently on the intrapelvic side of the acetabulum. We were unable to find an exact explanation for this finding and postulated that tumor cells might have been seeded into the inner wall of the acetabulum during acetabular preparation of the total hip prosthesis.- - - - - - - - - - ranking = 0.0066371254821194keywords = aneurysm (Clic here for more details about this article) |
8/18. Pseudoaneurysm of the superficial femoral artery associated with osteochondroma--a case report.Osteochondromas, the most common benign bone tumor, often go undetected and seldom cause significant clinical sequelae. Rarely they present as an arterial pseudoaneurysm, usually of the popliteal or superficial femoral artery. The authors present the case of a 14-year-old male with a distal superficial femoral artery pseudoaneurysm accompanied by distal embolization from a femoral exostosis.- - - - - - - - - - ranking = 1.9601772471073keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/18. Pseudoaneurysm of the popliteal artery as a complication of an osteochondroma. A review of the literature and a case report.False aneurysm of the femoral artery was associated with a solitary osteochondroma of the femur in a 22-year-old man. An extensive review of the literature and the problems related to diagnosis revealed that the aneurysm was apparently unique. Contrary to previous reports, computed tomography and angiography did not establish the diagnosis. The physical findings were more informative.- - - - - - - - - - ranking = 0.019911376446358keywords = aneurysm (Clic here for more details about this article) |
10/18. Malignant giant cell tumor of bone: malignant transformation of a benign giant cell tumor treated by surgery.A case of a giant cell tumor of the right proximal femur that developed malignant change following surgical treatment ("secondary" malignant giant cell tumor) is presented. The patient had a cystic lesion that was initially interpreted as an aneurysmal bone cyst. A local recurrence six months later demonstrated the histological features of typical giant cell tumor. A further recurrence 22 months after the original treatment showed histological malignancy. death was due to massive local recurrence and to extension of the malignancy to the pleura.- - - - - - - - - - ranking = 0.0033185627410597keywords = aneurysm (Clic here for more details about this article) |
