原发性胃恶性淋巴瘤的X线诊断(附8例分析)

原发性胃恶性淋巴瘤发病率仅次于胃癌，约占胃恶性肿瘤的5％左右，消化系统的恶性淋巴瘤中胃的发病率占首位，且经过手术治疗、放疗和化疗等综合治疗后的五年生存率在50％以上，因此X线检查是明确诊断及选择适当治疗方案的重要依据。……

胃恶性淋巴瘤的X线误诊分析

胃恶性淋巴瘤为少见病，系指原发于胃壁内淋巴系统的恶性肿瘤，占全部胃肠道淋巴瘤的1／3。临床表现无特异性，即与胃癌、胃溃疡、胃炎等临床表现相似。因此要在术前作出本病的诊断有相当大的难度，但本病与晚期胃癌的预后不同，且对放疗敏感，因此本病与胃癌的鉴别诊断具有十分重要的意义。本文就5例胃恶性淋巴瘤的X线误诊原因进行回顾性分析，力图找出其临床及X线表现要点，以帮助减少或避免对本病的误诊。

小儿纵隔恶性淋巴瘤的X线诊断

恶性淋巴瘤是发生在淋巴结的全身恶性肿瘤，包括何杰金氏病(HD)和非何杰金氏淋巴瘤(HHL)。纵隔内病变多与颈部及全身淋巴结同时发生，也可先在纵隔发生，最常见于中纵隔。本文就我院收治的经淋巴结活检针吸细胞学，骨髓涂片及部分胸内手术证实的17例小儿纵隔恶性淋巴瘤的X线表现作一报告。     

胃恶性淋巴瘤的X线诊断14例报告

<正> 胃恶性淋巴瘤比较少见,占胃恶性肿瘤的3—5％,临床上不易与胃癌相鉴别。预后较好,胃恶性淋巴瘤经综合治疗后五年生存率可达到50％左右。本文总结分析了经组织学证实的胃恶性淋巴瘤14例,以提高对其X线表现的认识。 1.临床资料 本组病例男性9例,女5例,年龄18—64岁,平均44岁。临床症状最常见的为上腹部疼痛,食欲减退及消化道出血,分别为79％、36％和33％,其它为恶心呕吐、消瘦乏力、饱胀等。最常见的体征为腹部包块,占     

骨恶性淋巴瘤的影像学诊断

目的：探讨骨恶性淋巴瘤影像学表现及诊断价值。方法：回顾性分析29例经手术病理证实的骨恶性淋巴瘤的临床和影像学资料，29例患者均行相应部位X线及CT检查，17例行MRI检查。结果：X线、CT表现为骨质破坏溶骨型6例，浸润型12例，骨质硬化型3例，混合型8例，包绕病骨生长并超越骨病变范围的软组织肿块14例，CT增强扫描呈中等均匀或不均匀强化；MRI表现为T2WI呈等或稍高信号12倒。呈明显均匀或不均匀强化。结论：X线对骨恶性淋巴瘤的检查有重要作用，其象牙椎、椎体多骨多灶性破坏、长骨溶骨性破坏等对本病有重要诊断价值。CT对本病的骨质破坏、硬化反应、骨膜反应、软组织侵犯等观察优于x线。MRI相对特征影像学特点为骨膜反应轻、T2WI稍高信号、软组织肿块较大、增强扫描不均匀强化。MRI对淋巴瘤浸犯性破坏所致的早期骨质改变。以及发现骨髓的早期侵犯优于x线和CT。

GASTROINTESTINAL TRACT CARCINOID RADIOLOGIC AND PATHOLOGIC MORPHOLOGY

The clinical, roentgenologic and pathologic manifestations of 51 cases of carcinoid tumors arising in the gastrointestinal (GD tract are re- viewed. Their distribution is a.s follows: s.mall bowel 29.4%, appendix 21.5%, colon 17.7%, stomach a.nd rectum 15.7%. The radiologic and pathologic changes are principally studied. The chief X-ray findings are submucous elevated lesion; coexis- tence of intra- and extraluminai tumor mass or fungoid filling defect; infiltrative signs of the intestinal wall and stretching and rigidity of the mucous folds, fixation and wide separation of the intestinal loorjs. narrOwing and partial obstruction of the intestine (signs. associated with desmoplastic reaction), etc. Grossly car- cinoid tumors can be classified into minimal, polypoid, giant massive and infiltrative types. .Microscopically it is composed of small cells, very seldom are atypia and mitotic figures seen.     

ARLY DETECTION AND CLASSIFICATION OF COLLAPSE OF FEMORAL HEAD AFTER TRANSCERVICAL FRACTURE

Long term follow up observations are carried out in 103 cases of avascular necrotic femoral head collapse after transcervical fractures. A method of detecting minimal femoral head collapse and classification of its stages and types are presented which helps early diagnosis, estimation of prognosis and selection of treat- ment. Criteria and radiologic signs for the detec- tion of femoral head collapse are: time of oc- currence, appearance of nail trace, recurrence of pain, gradual lowering of femoral head height and appearance of a sclerotic-radiolucent zone. A method of measuring femoral head height is .devised and reported. Correct interpretation of the criteria and radiologic signs during minimal collapse is con- sidered the key to increasing the efficacy of treatment. Femoral head collapse after transcervical fracture is classified int0 3 types, weightbearing area collapse, total collapse and subtotal collapse. Subtotal collapse is a new type proposed by the authors with its own clinical features. During the progressive stage, weightbearing area col- lapse retains the best function, subtotal collapse the next and total collapse the worst. Features of the quiescent stage of collapse are also classified int0 3 types, prognosis of the repair type is the best, sclerotic type the second and absorption type worst.

AREAE GASTRICAE COMPARATIVE PATHOLOGIC AND RADIOLOGIC STUDY ON 50 HUMAN STOMACH SPECIMENS

The comparative pathologic and radiologic study on 50 surgically resected specimens shows that the normal radiologic pattern of areae gastricae presents a regular-reticulated appearance. The abnormal areae gastricae are classified into four types: hyperplastic, atrophic, erosive, and destructive. The study of areae gastricae of the resected specimen may help improve radiologic diagnosis of minute mucosal changes of stomach, particularly in gastritis and early gastric carcinoma. However, its clinical application requires further investigation and improvement of the in vivo demonstration of areae Gastricae.
