790 Possible Causes for Cortical Thinning, Popliteal Swelling

  • Exostosis

    A 35-year-old woman presented with a painful pulsatile swelling in the lower medial aspect of the left thigh.[ncbi.nlm.nih.gov] […] bone (however pathologist usually only gets fragments) No bone marrow spaces Bone is covered by periosteum with overlying thin skin Advertisement[pathologyoutlines.com] Vascular complications of femur exostoses are rare, with popliteal pseudoaneurysm being the most common.[ncbi.nlm.nih.gov]

  • Fibroma

    thinning, erosion, slight expansion; - there are 2 subtypes; - fibrous cortical defect; - more common lesion; - is small 0.5 cm radiolucency w/ in cortex w/ sharply defined[wheelessonline.com] CT scan will show intact cortices with thinning. MRI will show intermediate signal on fat and fluid sensitive sequences characteristic of fibrous tissue.[orthopaedicsone.com] These images can also show cortical integrity (how thin the strong outer portion of the bone is in the region of the NOF) or a pathologic fracture.[orthoinfo.aaos.org]

  • Osteoclastoma

    Radiologically; the tumor appears as an eccentric lytic lesion with cortical thinning and expansion. There is absence of reactive new bone formation.[jemds.com] […] defined margins with cortical destruction and soft tissue extension Radiology images Contributed by Jesse Hart, D.O.[pathologyoutlines.com] […] involvement Campanacci grade II lesions ("active lesions") : well defined border; cortex is thinned and expanded Campanacci grade III lesions ("aggressive lesions") : ill[pathologyoutlines.com]

  • Lipoma

    Extension into an associated popliteal cyst has been reported. There is associated chronic inflammation reaction.[radiographics.rsna.org] In the remaining tumors, there is a thickening of cortical bone, concave cortical erosion, and/or bowing of the bone.[ijpmonline.org] Radiographs of patients with lipoma arborescens reveal soft-tissue swelling around the joint that may or may not be radiolucent.[radiographics.rsna.org]

  • Thrombosis

    BACKGROUND: Transient paraplegia of the lower limbs is a rare condition and, when has a vascular etiology, is usually associated with thromboembolic events, aortic dissection, aortic aneurysms, or as a complication of the surgical correction of those diseases. There is no case reported of acute paraplegia caused by[…][ncbi.nlm.nih.gov]

  • Varicose Veins

    Pain, aching, swelling, and ulceration can result from varicosities or venous malformations in Klippel-Trenaunay syndrome patients (, 24 ).[dx.doi.org] While all of the leg veins with the lower inferior vena cava can be affected, the popliteal and superficial femoral veins are most frequently involved (, 34 ).[dx.doi.org]

  • Thrombophlebitis

    Superficial vein thrombophlebitis is the common vascular symptom in Behçet disease and is characterized as erythema nodosum-like eruptions. Some studies have reported the presence of antiphospholipid antibodies (Abs) in patients with Behçet disease. We measured lupus anticoagulant, anticardiolipin,[…][ncbi.nlm.nih.gov]

  • Periostitis

    Chronic osteomyelitis with proliferative periostitis is a rare form of osteomyelitis that is characterised by new bone formation with periosteal reaction. It is also traditionally known as Garre's osteomyelitis. The common sources of infection of the jaw include dental caries associated with periapical periodontitis,[…][ncbi.nlm.nih.gov]

  • Popliteal Cyst

    By Baker cyst or popliteal cyst is a soft-tissue swelling in the posterior aspect of the knee which contains gelatinous fluid. It is called Baker Cyst after Dr.[boneandspine.com] The examination reveals a swelling which is located distal to the popliteal crease, which becomes prominent when a knee is hyperextended but disappears upon flexion.[boneandspine.com] BACKGROUND: A popliteal cyst is a benign swelling with synovial fluid located behind the knee joint.[ncbi.nlm.nih.gov]

  • Popliteal Aneurysm

    We present a patient with a remarkably large popliteal aneurysm of 10 cm presenting as a popliteal swelling with foot drop and no signs of limb ischemia.[ncbi.nlm.nih.gov] popliteal fossa, local pain and the post-phlebitic syndrome.[ajol.info] During hospitalization for sepsis, he developed acute right knee pain and swelling.[ncbi.nlm.nih.gov]
