ジャーナル フリーThe difference between the radiographic images of phlebolith arising in hemangioma and those of sialolith in Wharton's duct were examined and discussed comparatively. The image of stratified calcification (so-called "target pattern"), which has been described as a characteristic radiographic image in phlebolith and rarely found in sialolith, could be seen in only medium size (3-10mm) of phlebolith. Smaller phlebolith (<3mm) were round and showed a uniform radiodensity, while larger one (>10mm) were irregular-shaped in part, and revealed a mixed radiodensity. Unexpectedly in sialolith, however, these stratified structures were found frequently but less in phlebolith. In general, sialolith showed elliptical or irregular shape and those borders were more obscure than those of phlebolith.
Sturge-Weber syndrome in the jaw bones and central hemangioma of the jaw were also examined by radiographs comparatively. Cancellous spaces of alveolar bone involved in hemangioma (cancellous type) were larger but those spaces seen in Sturge-Weber syndrome were smaller than those of normal variants. In four cases having similar clinical signs found in Sturge-Weber syndrome, abnormal radiographic findings, i. e., hypertrophy of alveolus, asymmetry of maxillary antrums and jaws, and malocclusion were obtained. Therefore, even if those lesions have not complete symptoms required for the diagnosis of Sturge-Weber syndrome, they should be considered to have different categories from usual hemangioma occurring in oral cavity and classified as a syndrome with hemangioma or Sturge-Weber syndrome allied lesion.抄録全体を表示PDF形式でダウンロード (6685K) -

ジャーナル フリーSince the radiographic features of odontogenic keratocyst resembles those of ameloblastoma very often, especially in the mandibular molar and ramus regions, it is very difficult or might be impossible to differentiate odontogenic keratocyst from ameloblastoma solely by the radiographs. The purpose of this paper is to obtain some informations for the differential diagnosis of odentogenic keratocyst from ameloblastoma by the analysis of the radiographic findings of these lesions.
The overall study of 110 cases of odontogenic keratocyst revealed that it occurred predominantly in the third decade, and mandible was more commonly affected. The ramus was involved most often in the mandible. Forty-six cases of odontogenic keratocyst and 40 cases of ameloblastoma which involved the mandibular ramus were selected and studied in relation to the type of cystic form, the tooth behavior, and bone expansion. More than a half of the odontogenic keratocyst showed multilocular type and the margin of unilocular type revealed smooth or less scalloped periphery. Tooth migration and root resorption were rather mild in contrast with the findings of ameloblastoma. The most significant finding was the less degree of bone expansion in the mandibular ramus. The measurement of expansion rate indicated the characteristics of this cyst, which may be of great help to differentiate this lesion from ameloblastoma.抄録全体を表示PDF形式でダウンロード (5011K) -

ジャーナル フリーThree cases of chondrosarcoma of the jaw were reported mainly from the standpoint of the radiographic features in conjunction with the histopathological findings. One was a chondrosarcoma of osteolytic type involving the anterior part of the upper jaw, while the others were the less destructive one in the mandibular ramus showing somewhat benign nature, and the exophytic tumor with the maked radiopacities in the body of the lower jaw proven histopathologically to be mesenchymal chondrosarcoma.
Since the radiographic appearances of chondrosarcoma varied to a large extent, a careful attention should be paid to the diagnostic procedure. It might be suggested that the radiographic findings were related to the cytologic features in the cartilagenous components of this tumor tissue.抄録全体を表示PDF形式でダウンロード (10928K) -

ジャーナル フリー1. 12 patients diagnosed as mucopolysaccharidosis (Hurler syndrome-3 cases, Scheie syndrome-1 case, Hunter syndrome-3 cases, Sanfilippo syndrome-2 cases, Morquio syndrome-3 cases) and 2 patients diagnosed as mucolipidosis (I-cell disease) were reviewed radiographically.
2. The localized dentigerous cyst-like bone changes and hypoplastic condyles in jaws were defined as two major radiographic key signs in mucopolysaccharidosis and I-cell disease.
3. Through published literatures and our radiograms, the localized dentigerous cystlike bone changes were probably related closely to the storage of mucopolysaccharide, and abnormal hypoplastic condyles were possibly caused by the unbalance of bone metabolism in mandibular ossification.
4. The radiographic findings of enlarged pulp chamber were found to be a new sign in affected teeth.
5. Mucopolysaccharidosis might be subsequently detected following minor X-ray findings, i. e., spacing of teeth, mandibular prognathism and underdevelopment of maxilla, etc, and with together two major key signs described above.抄録全体を表示PDF形式でダウンロード (5621K) -
