1/6. Prominent Tc-99m MIBI skeletal uptake in renal osteodystrophy: a possible role for whole-body scanning.renal osteodystrophy is a process whereby renal failure causes profound bone disease. Effects on bone include osteosclerosis, osteomalacia, osteoporosis, pathologic fractures, aseptic necrosis of the hips, and bone pain. The authors present a case of renal osteodystrophy with intense Tc-99m 2-methoxy isobutyl isonitrile (MIBI) radiotracer uptake in the mandible and propose that Tc-99m MIBI may have a potential role in diagnosing renal osteodystrophy.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/6. Localized jaw enlargement in renal osteodystrophy: report of a case and review of the literature.renal osteodystrophy is a common long-term complication of end-stage renal disease. Involvement of the jaws is common and radiographic alterations are often one of the earliest signs of chronic renal disease. However, marked enlargement of the jaws is a rare complication of renal osteodystrophy. A case of localized asymptomatic enlargement of the mandible in a 38-year-old woman with chronic renal failure is presented. The clinical, radiographic, and histological findings were consistent with renal osteodystrophy. To our knowledge, this is the third case of localized mandibular enlargement of renal osteodystrophy reported in the English-language literature.- - - - - - - - - - ranking = 20.708039152395keywords = jaw, mandible (Clic here for more details about this article) |
3/6. Leontiasis ossea in a patient with hyperparathyroidism secondary to chronic renal failure.osteitis fibrosa describes the bone changes seen in renal osteodystrophy secondary to longstanding hyperparathyroidism. We report a 19-year-old man with longstanding chronic renal failure with a severe form of osteitis fibrosa affecting the jaws and other maxillofacial bones causing bizarre facial and dental deformity in a patient-uraemic leontiasis ossea.- - - - - - - - - - ranking = 3.2846731920659keywords = jaw (Clic here for more details about this article) |
4/6. Macrognathia secondary to dialysis-related renal osteodystrophy treated successfully by parathyroidectomy.renal osteodystrophy (ROD) is one of the most common complications affecting patients with chronic renal failure both before and after the initiation of maintenance dialysis, but macrognathia secondary to ROD is rare. Usually, enlarged jaws due to ROD do not return to their normal contours after the treatment of hyperparathyroidism. To the authors' knowledge, this article describes the second case of macrognathia secondary to dialysis-related ROD treated successfully by parathyroidectomy. Immunohistochemical study of the maxilla confirmed that parathyroidectomy could stop maladaptive parathyroid hormone stimulation, which leads not only to the formation of osteoblastic progenitors that become fibroblast-like cells but also to osteoclast formation.- - - - - - - - - - ranking = 3.2846731920659keywords = jaw (Clic here for more details about this article) |
5/6. An unusual manifestation of renal osteodystrophy.Besides the more frequent aspects, an unusual manifestation of renal osteodystrophy occurred in a 19-year-old man on regular hemodialysis treatment. About 6 years after the start of hemodialysis, the patient, who had severe osteodystrophy, presented a brown tumor, localized to the jaw, which caused a serious deformity of the face. Pharmacological treatment for hyperparathyroidism did not reduce the volume of the mass. Only total surgical removal gave long-lasting success. Brown tumor is an unusual but serious complication of renal bone disease which can be treated successfully by surgical removal of the tumoral mass and by pharmacological treatment for hyperparathyroidism.- - - - - - - - - - ranking = 3.2846731920659keywords = jaw (Clic here for more details about this article) |
6/6. Changing manifestations of brown tumors on bone scan in renal osteodystrophy.In a patient with chronic renal failure and secondary hyperparathyroidism, brown tumors, visualized initially as photon-deficient areas on bone scintigraphy, reverted to areas of abnormally increased activity following parathyroidectomy. This dual appearance on bone scan paralleled the functional state of the parathyroid gland. The possible relationship of hyperhosphatemia to the increased bone-scan activity noted in the calvarium, mandible, and facial bones is discussed.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
