Abstract

Background

Although ventilation/perfusion (V/Q) scintigraphy is frequently used in the diagnosis of acute or chronic pulmonary embolism (PE), it also plays a significant role in diagnosing pulmonary vascular diseases. Additionally, in the presence of a mismatch defect on V/Q scintigraphy, pulmonary vascular anomalies should be considered as a possible alternative to PE. For this reason, we aimed to present three cases with Swyer–James–MacLeod syndrome (SJMS), one of which was also complicated by PE, and one case with pulmonary artery hypoplasia.

Case Presentation

Case 1: PE was diagnosed by V/Q scintigraphy in a patient with known SJMS. Case 2: SJMS was diagnosed by thoracic computed tomography (CT), flexible optical bronchoscopy (FOB) and V/Q scintigraphy. Case 3: V/Q scintigraphy revealed pulmonary artery hypoplasia in the differential diagnosis of PE when evaluated together with FOB and thoracic CT. Case 4: Diagnosed as SJMS by Thorax CT and V/Q scintigraphy in the presence of chronic lung disease.

Conclusions

V/Q scintigraphy is also used in the diagnosis of congenital/hereditary vascular and airway diseases. Thoracic CT should be performed together with evaluation to reach the diagnosis in this group of patients. In cases with mismatch defects, vascular anomalies should also be considered in the differential diagnosis.

肺血管异常患者的通气/灌注显像。
背景:虽然通气/灌注(V/Q)显像常用于诊断急慢性肺栓塞(PE),但在肺血管疾病的诊断中也有重要作用。此外,在V/Q显像上存在错配缺陷时,应考虑肺血管异常作为PE的可能替代方案。因此,我们的目的是报告3例Swyer-James-MacLeod综合征(SJMS),其中1例合并PE, 1例合并肺动脉发育不全。病例介绍:病例1:在已知SJMS患者中,通过V/Q显像诊断PE。病例2:经胸部CT、柔性光学支气管镜及V/Q显像诊断为SJMS。病例3:V/Q显像显示肺动脉发育不全与FOB和胸部CT鉴别诊断PE。病例4:有慢性肺部疾病,经胸腔CT及V/Q显像诊断为SJMS。结论:V/Q显像可用于先天性/遗传性血管及气道疾病的诊断。本组患者需同时行胸部CT检查,以达到诊断目的。在有错配缺陷的病例中,在鉴别诊断中也应考虑血管异常。

期刊介绍: Clinical Physiology and Functional Imaging publishes reports on clinical and experimental research pertinent to human physiology in health and disease. The scope of the Journal is very broad, covering all aspects of the regulatory system in the cardiovascular, renal and pulmonary systems with special emphasis on methodological aspects. The focus for the journal is, however, work that has potential clinical relevance. The Journal also features review articles on recent front-line research within these fields of interest. Covered by the major abstracting services including Current Contents and Science Citation Index, Clinical Physiology and Functional Imaging plays an important role in providing effective and productive communication among clinical physiologists world-wide.
