1/7. Ganglion of the hip joint--we present a logical approach to the exploration of a mass in the femoral triangle.hip joint ganglion is a rare cause of a mass in the femoral triangle. Our patient presented with a swelling in the groin and a history of femoral hernia repair 5 years previously. Pre-operative assessment with ultrasound suggested a possible femoral artery aneurysm. We propose that safe exploration of a mass closely related to the femoral vessels must include vascular control.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/7. Inguinal mass as a late complication of hip arthroplasty. Differential diagnosis and treatment from a vascular surgical perspective.We report on three patients with a symptomatic inguinal mass as a late complication of repetitive arthroplastic hip surgery. In one case, there was a false aneurysm and in two cases a so-called "synovial cyst". A synovial cyst is usually an enlarged iliopsoas bursa in communication with the capsule of the hip joint. Hypersecretion in arthritic joints may cause expansion of this bursa. Compression of the common femoral and external iliac veins may lead to outflow obstruction and leg swelling. The most important diagnostic tools are plain films of the hip joint and ultrasound of the groin including colour-coded assessment of the femoral vessels. Symptomatic cysts usually need removing by an anterior approach. Loose arthroplastic components can be causative and should be replaced.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/7. Compression of the iliac vein by a synovial cyst.While a synovial cyst of the hip is a rare cause of lower limb swelling, a differential diagnosis of deep vein thrombosis is needed. A case of lower limb swelling due to compression of the external iliac vein by a synovial cyst is presented with a review of the literature. Sagittal views and three-dimensional images of a CT scan were very useful for the diagnosis. This is the first review in English of vessel compression by a synovial cyst of the hip.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/7. Lumbar hemorrhagic synovial cysts: diagnosis, pathogenesis, and treatment. Report of 3 cases.BACKGROUND: To define the etiologic, clinical, histological, and surgical features of lumbar hemorrhagic synovial cysts (LHSCs). Three personal cases are reported together with a review of the pertinent literature. methods: We identified 3 cases of LHSC treated in our departments and 20 cases culled from the literature. RESULTS: A total of 23 cases of LHSC were selected. All the patients underwent surgical treatment because of untreatable radicular pain and/or neurological deficits. The amount of bleeding, either massive or minor but repeated, influenced the timing of surgery. In our cases, the histological examinations showed an inflammatory reaction within the cyst and the consequent formation of neoangiogenic vessels. CONCLUSIONS: Hemorrhagic synovial cyst of the spine is rare and its most common localization is lumbar. Bleeding within the cyst leads to an increase of its volume, accompanied by neurological deficits and/or painful symptoms that are violent and generally intractable. In this event, surgical excision is the treatment of choice and, in some cases, emergency surgery is necessary. Hemorrhages are probably caused by the rupture of fragile neoangiogenic vessels.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
5/7. Computed tomography of extraosseous ganglia.Computed tomography (CT) was performed in six patients with painful soft-tissue masses where sarcoma was suspected. Incisional or excisional biopsy proved all to be extraosseous ganglia. CT delineated the anatomic relationships of the masses. The CT density of four of the ganglia was 18 Hounsfield Units (HU), consistent with that of fluid-filled lesions. Contrast medium did not enhance the lesions on CT. angiography was performed in four cases and demonstrated hypovascular masses with no vessel displacement. Plain radiographs and technetium bone scintigrams were nonspecific. CT was the best preoperative confirmation of the diagnosis of benign extraosseous ganglia and the best method of localizing the lesions with respect to surrounding bone and soft tissues.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/7. tibial nerve entrapment by a Baker cyst: case report.We report a rare case of degenerative joint disease of both knees, complicated by a Baker cyst. Our emphasis is on the role of electromyography and electrodiagnosis in the localization of this nerve entrapment syndrome. The patient presented with pain and swelling; venography revealed deep venous thrombosis of the right calf, including the popliteal and proximal superficial femoral vessels. The patient responded well to bed rest, analgesics, intravenous heparin and subsequent Coumadin anticoagulation, and was discharged two weeks later. Five weeks after onset of these acute problems, nerve conduction studies were done, leading to a diagnosis of Baker cyst with nerve entrapment. He responded well to knee joint aspiration and intraarticular prednisolone injection. Some evidence of improvement in the flexor hallicus longus muscle was detected at three-month follow-up.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/7. Giant synovial cyst of the hip: an unusual presentation with compression of the femoral vessels.A case of synovial cyst of the hip with symptomatic compression of the femoral vessels is described. A 75-year-old woman with severe unilateral osteoarthritis of the right hip was referred because of an intermittent, unpleasant sensation of coolness in the right foot and hip pain. A large mass was palpable in the femoral triangle. Computed tomography and arthrography revealed a large cyst communicating with the hip joint and compressing the femoral vessels ventrally. Total hip arthroplasty was carried out, and the stalk communicating with the cyst was ligated and divided. The unpleasant sensation of coolness in the right foot disappeared postoperatively. The authors concluded that iliopsoas bursitis should be considered in the evaluation of a patient with nonspecific pelvic or groin pain. As demonstrated in this rare case, the main symptom may be misleading and the typical syndrome of a tender groin mass with an underlying history of rheumatoid arthritis may be absent. Treatment should be directed to the underlying joint disease.- - - - - - - - - - ranking = 6keywords = vessel (Clic here for more details about this article) |
