非典型结节病21例临床分析

目的　提高对非典型结节病的认识。方法　回顾性分析了２１ 例非典型结节病的临床资料,所有病例均经病理检查证实。结果　不典型结节病影像学可表现为：（１）肺内病变：有孤立结节影,肺不张,单侧、双侧肺实变,双肺栗粒样结节。（２） 单纯纵隔淋巴结病变：有纵隔肿物,纵隔淋巴结肿大和单侧肺门淋巴结肿大,纵隔单纯淋巴结肿大。（３） 胸膜病变：有液、气胸,胸膜增厚。（４） 肺门病变：有单侧肺门淋巴结肿大和纵隔淋巴结肿大,双侧肺门淋巴结非对称性肿大, 单侧肺门淋巴结肿大钙化。结论　不典型结节病临床表现多种多样,影像学检查难以满足诊断需要。只有对结节病有足够认识,辅以其他检查,其诊断并不困难。     

老年前期及老年人胸部结节病的CT表现

目的：总结老年前期及老年胸部结节病患者的CT表现。方法：回顾性分析25例确诊的老年前期及老年胸部结节病患者的CT图像。结果：9例CT呈典型表现，16例CT呈不典型表现，其中纵隔和一侧肺门淋巴结肿大者3例（3／25），无肺门淋巴结肿大的单纯纵隔淋巴结肿在者7例（7／25），无纵隔淋巴结肿大的单侧肺门淋巴肿大者1例（1／25），仅有肺部改变而无胸部淋巴结肿大者5例（5／25）。后者在首诊时全部误诊。结论：老年人胸部结节病的CT表现多不典型，认识此种表现在诊断中很重要。

结节病多累及肺部，主要靠影像学诊断及判断预后，本综述了结节病的胸片表现，并对其进行分期，对典型和非典型的胸片进行分析。胸部ＣＴ扫描提高纵隔及肺门淋巴结肿大的检出率，是发现结节病患肺实变的敏感方法。     

以胸膜广泛侵犯为表现的结节病一例并文献复习

<正>结节病因其最常累及肺及淋巴系统,在肺部最常表现为肺门淋巴结肿大和肺纤维化,故在内科学上被列为间质性肺疾病的范畴~([1])。结节病Ⅱ期表现为双肺门淋巴结肿大及肺内病变时鉴别诊断困难,尤其是与结核病的鉴别。结节病虽属于多系统受累的疾病,但胸膜累及并出现双侧胸腔积液并不常见。现将我科经胸腔镜诊断表现为胸膜广泛累及的1例结节病报道如下,以提高临床医师对于该病的认识。临床资料患者,女性,63岁。主因咳嗽6个月、气短1个月入院。

The features of cases of intrathoracic lymphomas

In this study, 18 patients who had been diagnosed as intrathoracic lymphoma between January 1999 and August 2001 had been evaluated retrospectively to guide the diagnostic approaches. 12 (66.6%) of the patients were male and 6 (33.4%) were female. The mean age was 46.47 +/- 17.31. The leading symptoms were disapnea, cough, weight loss and fever. The most frequently seen laboratory findings were decreased hemoglobin and hematocrit rates (72.2%) and increased Lactate Dehydrogenase levels (44.4%). Radiologically, 18 (100%) patients had mediastinal lymph node enlargement, 8 (44.4%) patients had bilateral and 6 (33.3%) had unilateral hilar enlargement, 3 (16.6%) patients had appearance of mass lesion, 1 (5.5%) had appearance of consolidation, 2 (11.1%) patients had atelectasis, 3 (16.6%) patients had appearance of pleural effusion. Histopathological diagnosis were undertaken with lymph node biopsies in 11(61.1%) patients, with bronchial biopsies in 2 (11.1%) patients, with pleural biopsy in 1 (5.5%) patient, with lymph node and bronchial biopsies in 3 (16.6%) patients, with lymph node and pleural biopsies in 1 (5.5%) patient. 11 (61.1%) patients were diagnosed as Hodgkin Disease (nine as nodular type, two as mixed cellular type). 7 (38.9%) patients were diagnosed as non Hodgkin Lymphoma. After taking diagnosis the patients were sent to medical oncology clinics for follow up and therapy. These findings showed that different locations of intrathoracic lymphomas could be seen with nodal or extranodal presentations so it must be taken into account in differential diagnosis of other pathological conditions.

Computed tomographic scanning in sarcoidosis

Sarcoidosis is a granulomatous disease of unknown etiology that involves the lungs or intrathoracic lymph nodes in more than 90% of patients. The clinical spectrum of sarcoidosis is protean, but pulmonary manifestations often dominate. Chest radiographs are abnormal in 90 to 95% of patients with sarcoidosis; the most characteristic feature is bilateral hilar lymphadenopathy (BHL), present in 50 to 80% of patients. Pulmonary parenchymal infiltrates are present in 25 to 50% of patients. In this article, we review the radiographic features of sarcoidosis (both typical and atypical), and the impact of chest radiographic stage on long-term prognosis. Computed tomographic (CT) scans are more sensitive than chest radiographs in delineating parenchymal, mediastinal, and hilar structures, and distinctive CT patterns may be virtually pathognomonic for sarcoidosis in some patients. Routine CT scan is not appropriate to diagnose or manage sarcoidosis, but CT may be invaluable in patients with atypical clinical or chest radiographic findings or specific complications of sarcoidosis (pulmonary or extrapulmonary), or to assess prognosis. High-resolution thin-section CT scans (HRCT) may be helpful in selected patients with stage II or III sarcoidosis to discriminate active inflammation from irreversible fibrosis. This article discusses the salient HRCT features of sarcoidosis, accuracy of CT in the differential diagnosis, and correlations of HRCT with disease extent and activity, pulmonary function, and lesion reversibility.     

肺结节病的临床研究

目的 提高对结节病的认识。方法 回顾分析经病理确诊的结节病21例患的临床资料。结果 胸部结节病多数有双侧肺门阴影对称性增大占（71％）。62．5％的患支气管肺泡灌洗液中CD4／CD8＞3．5。90．4％的患PPD为阴性。纤支镜支气管粘膜和肺活检及胸部小切口开胸肺活检病理确诊阳性率分别为80％和100％。结论 胸部X线,PPD及支气管肺泡灌洗液CD4／CD8检查对诊断结节病十分重要。经纤支镜支气管粘膜和肺活检和胸部小切口开胸肺活检简便易行,创伤小,阳性率高的方法,特别是后对疑难病例的确诊有重要的临床价值。     

A study on the problems of the radiologic manifestations in sarcoidosis

Unilateral hilar adenopathy, which is considered as an atypical manifestation of sarcoidosis, appeared only on the initial stage, and eventually became bilateral. The adenopathy may occur in all groups of the mediastinal lymph nodes. The roentgenological findings of the pulmonary parenchymal lesions include interstitial, alveolar, miliary and fibrous lesions. The alveolar involvement, and the pathological consideration of pseudoalveolar manifestations in X-ray film were discussed.     

CD8+ cell-dominant alveolitis in pulmonary sarcoidosis

A 55-year-old woman had bilateral hilar lymphadenopathy and retinouveitis. Microscopic examination of a biopsy specimen from a mediastinal lymph node revealed noncaseating epithelioid cell granulomas. Since granulomatous diseases of infectious origin and sarcoid reaction were reasonably excluded, she was diagnosed as having pulmonary sarcoidosis. Bronchoalveolar lavage findings were atypical in that the ratio of helper T cells to suppressor T cells (CD4/8 ratio) was 0.5 in two separate examinations, despite a moderately increased proportion of lymphocytes. Immunohistochemical examination of the lymph node also showed a predominancy of suppressor T cells. The inversion of the CD4/8 ratio suggests the presence of heterogeneity in the immunoregulatory mechanism in pulmonary sarcoidosis and may have a prognostic significance.
