Using the radiological -- pathological comparision method, 227 cross sections wereexamined from 11 resected specimen of pathologically -- convinced large intestinal carcinoma with complete radiological data. The results showed that 1) Arround carcinoma the intedece between carcinoma and mucosa was actually the interface between carcinoma and chronic inflammation;2) The X--ray manifestaation of mucosal plicae decreasing and irregular area pathologically speaking were completely the junction area of carcinoma and inflammation, 3) Radiological mucosal disappeared area were pathologically submucosal edema, adenomatoid hyperplasia and glandular epithelium atypical hyperplasia, besides, a little carcinama tissue could be seen insubmucosa. So more attentions should be paid to decide the invasive range of the carcinoma,4) Meanwhile, the chronic inflammation in proximal portion of mucosa arround the carinoma was more severer than that of distal portion, so was the glandular epitheliam atypical hyperplasia. When the occurrence and development of large intestinal carcinoma were surveied, it is suggested that more attention should be paid to the radiological and pathological manifestation of the proimal portion of the intestinal mucosa arround the carcinoma.

用X线-病理对照方法,对经手术病理证实,并有较完整X线资料的11例大肠癌手术切除标本进行了227处切面的观察。结果发现1)癌瘤与周边粘膜的交界面,实际是癌瘤与慢性炎症的交界面;2)X线表现粘膜皱襞减少及不规则区,病理所见全部是癌组织与炎症组织的交界区;3)X线显示粘膜皱襞消失区,其病理改变除了粘膜下水肿、腺体腺瘤样增生及腺上皮不典型增生外,在粘膜下层还可以见到少量癌组织,因此在确定癌瘤侵犯范围时应引起注意;4)同时癌瘤近端周边粘膜的重度慢性炎症较远端周边显著,说明在监测大肠癌的发生与发展时,更应注意癌瘤近端周边肠管的X线病理改变。

Objective:To further study the pathogenesis of classic Schm orl′s nodes based on clinical practice.Methods:A patient with severe low back pain was found that the irregularity of the endplates and the presence of Schm orl′s nodes in L2 - 3 and L3- 4spaces in lumbar radiographs.Two painful intervertebral discs with Schm orl′s nodes in their superior or inferior endplates were identified by discography and pain provocation.Two foci of Schnorl′s nodes were rem oved in en bloc via a retroperitoneal approach for...

目的 :从临床实际工作出发 ,对传统意义上的 Schmorl结节进行再认识。方法 :1例严重下腰痛患者 ,腰椎 X线摄片提示 L3- 4和 L4 - 5椎间隙上下终板不规则 ,L3椎体前下缘及 L5椎体前上缘 Schm orl结节形成 ,对其进行腰椎间盘造影及 CT检查 ,并对手术切除的 Schm orl结节病灶进行组织学分析。结果 :椎间盘造影术显示部分造影剂渗入 Schmorl结节形成处浅层。腰椎 CT扫描发现 Schmorl结节形成区腰椎软骨终板下有一类圆形、多囊状骨质密度不规则区 ,呈骨坏死样改变 ;组织学检查证实该骨密度不规则区为骨坏死区。 结论 :研究结果显示此例患者的 Schm orl结节实际上是椎体软骨终板下的片状骨坏死灶 ;提示有必要对 Schmorl结节的形成进行再认识。

Objective:To study the pathogenesis of Schmorl′s node formation and the relationship between Schmorl′s node formation and some low back pain or disc degeneration.Method:12 Schmorl′s nodes derived from ten patients who had severe low back pain with or without leg pain.Superior or inferior end-plate occurring Schmorl′s node in painful intervertebral disc was confirmed by discography.The samples of all Schmorl′s nodes were prepared in integrity for histological examination also.Result:CT scanning showed that there...

Objective:To study the pathogenesis of Schmorl′s node formation and the relationship between Schmorl′s node formation and some low back pain or disc degeneration.Method:12 Schmorl′s nodes derived from ten patients who had severe low back pain with or without leg pain.Superior or inferior end-plate occurring Schmorl′s node in painful intervertebral disc was confirmed by discography.The samples of all Schmorl′s nodes were prepared in integrity for histological examination also.Result:CT scanning showed that there was a round-like and multicystic irregular region of bone dense in the area of Schmorl′s node formation under cartilage end-plate,which presented osteonecrosis changes.The focus of the osteonecrosis was surrounded by an indistinct sclerotic margain.Schmorl′s nodes showing in X-ray films or irregular regions of bone dense under cartilage end-plate showing in CT scanning were osteonecrosis zone actually in histology.The cartilage end-plate over surface of osteonecrosis zone was basically intact.Under cartilage end-plate,marrow cavities showed fibrosis,including fatty cell disappearance and fibroplasia,and osteocytes within bone trabecula disappeared or died.Conclusion:Classic Schmorl′s nodes showing radiographically are osteonecrosis zones.The cartilage end-plate over surface of osteonecrosis zone often is intact.Nucleus pulposus herniation into vertebral body or not is not related to Schmorl′s node formation.

目的:探讨腰椎Schmorl结节的形成及其与下腰痛和椎间盘退变的关系。方法:12个下腰椎Schmorl结节来自10例严重下腰痛伴或不伴坐骨神经痛患者。均行腰椎X线摄片和CT扫描,并将术中完整切除的12个Schmorl结节病灶标本作组织学检查。结果:CT扫描发现Schmorl结节形成区软骨终板下有一类圆形、多囊状骨密度不规则区,边缘通常硬化,呈骨坏死改变。组织学检查发现,在CT片上显示的骨密度不规则区实际上是骨坏死区。骨坏死区表面的软骨终板通常完整,软骨下髓腔内脂肪细胞消失,大量纤维组织增生和缺血性纤维软骨形成,小梁骨内骨细胞消失或死亡,形成空骨陷窝。结论:X线片上显示的经典Schmorl结节实际上是椎体软骨终板下的片状骨坏死灶,软骨终板通常是完整的,有无髓核突出与Schmorl结节形成无关。
