  1. TheRadiologyofBenign Neoplasms A. Ruprecht D.D.S., M.Sc.D., F.R.C.D.(C) Gilbert E. Lilly Professor of Diagnostic Sciences Professor and Director of Oral and Maxillofacial Radiology Professor of Radiology Professor of Anatomy and Cell Biology

  2. TheRadiologyofBenign Neoplasms II. Non-Odontogenic

  3. Giant cell lesion Hemangioma (Haemangioma) Neurofibroma Fibroma Osteoma Osteoblastoma Chondroma The Radiology of Benign Neoplasms Non-Odontogenic

  4. Giant cell lesion Hemangioma (Haemangioma) Neurofibroma Fibroma Osteoma Osteoblastoma Chondroma The Radiology of Benign Neoplasms Non-Odontogenic

  5. Giant cell lesion The Radiology of Benign Neoplasms • Central giant cell lesion • Central giant cell granuloma • Peripheral giant cell lesion • Peripheral giant cell granuloma • Giant cell tumor • True giant cell tumor

  6. Giant cell lesion The Radiology of Benign Neoplasms • Central giant cell lesion • Central giant cell granuloma • Peripheral giant cell lesion • Peripheral giant cell granuloma • Giant cell tumor • True giant cell tumor

  7. Central giant cell lesion Central giant cell granuloma The Radiology of Benign Neoplasms • before 21 years • unknown nature • anterior to first permanent molars • painless

  8. Central giant cell lesion Central giant cell granuloma The Radiology of Benign Neoplasms • radiolucent, with “salt and pepper “ calcification • thin, wispy septa • resorption of teeth very common

  27. Giant cell lesion The Radiology of Benign Neoplasms • Central giant cell lesion • Central giant cell granuloma • Peripheral giant cell lesion • Peripheral giant cell granuloma • Giant cell tumor • True giant cell tumor

  28. Giant cell tumor True giant cell tumor The Radiology of Benign Neoplasms • after 21 years • rare in jaws • posterior to first permanent molars • painful

  29. Giant cell tumor True giant cell tumor The Radiology of Benign Neoplasms • considered by some to be variant of GCG • radiographic appearance similar to GRG

  30. Giant cell lesion Hemangioma (Haemangioma) Neurofibroma Fibroma Osteoma Osteoblastoma Chondroma The Radiology of Benign Neoplasms Non-Odontogenic

  31. Hemangioma Haemangioma The Radiology of Benign Neoplasms • Intraosseous hemangioma • Extraosseous hemangioma

  32. Hemangioma Haemangioma The Radiology of Benign Neoplasms • Intraosseous hemangioma • Extraosseous hemangioma

  33. Intraosseous Hemangioma The Radiology of Benign Neoplasms • somemay be true neoplasms, • most are probably developmental • uncommon • no phleboliths

  34. Intraosseous Hemangioma The Radiology of Benign Neoplasms • altered bone pattern • “moth-eaten” bone pattern • hypoplastic teeth

  40. Extraosseous Hemangioma The Radiology of Benign Neoplasms • may be some true neoplasms, • most are probably developmental • common • phleboliths

  41. Extraosseous Hemangioma The Radiology of Benign Neoplasms • may have hypo- or hyperplasia of • neighboring bone
