Characteristic multimodal imaging of palatal follicular lymphoma: a case report on effectiveness of CT, diffusion-weighted MR imaging and intraoral ultrasonography

Panoramic radiography and computed tomography of metastatic breast carcinoma in the mandible: Report of a case

“…Regarding the differential diagnosis including oral mucosal origin malignancies prior to the biopsy and the anti-resorptive agent-related osteomyelitis of the jaw, Ogura et al [9][10][11] showed CT imaging of mandibular malignant tumors and inflammatory lesions (malignant lymphoma, osteolytic lesion with the destruction; squamous cell Class II, invasion confined to the alveolus; Class III, invasion extending to the bone area between the alveolus and the mandibular canal; and Class IV, invasion beyond the mandibular canal. Minami et al 13 showed that CT showed focal erosion of the maxilla by follicular lymphoma. We consider that the findings of extranodal malignant lymphoma originated from gingiva not gingival squamous cell carcinoma, such as the osteolytic lesions and erosion of the jaw, were similar to ours.…”

“…Furthermore, Ogura et al 12 indicated that the CT images of mandibular bone invasion by gingival squamous cell carcinoma were classified into four types: Class I, no bone invasion; Class II, invasion confined to the alveolus; Class III, invasion extending to the bone area between the alveolus and the mandibular canal; and Class IV, invasion beyond the mandibular canal. Minami et al 13 showed that CT showed focal erosion of the maxilla by follicular lymphoma. We consider that the findings of extranodal malignant lymphoma originated from gingiva not gingival squamous cell carcinoma, such as the osteolytic lesions and erosion of the jaw, were similar to ours.…”

“…For a definitive diagnosis, histological evaluation is necessary. Recently, diffusion‐weighted MR imaging 13 and SPECT/CT 14 have been applied for jaw pathologies. We consider that the diffusion‐weighted MR imaging and SPECT/CT can be an effective tool for the quantitative evaluation of jaw pathologies.…”
