TABLE 3.
The most common radiologic features of pleuropulmonary paragonimiasisa
| Radiographic feature | Frequency (%)
|
|
|---|---|---|
| Avg (no. with finding/no. examined for finding) | Range | |
| Consolidation | 58 (123/211) | 52-68 |
| Pleural effusions | 51 (108/211) | 10-66 |
| Cystic lesions | 32 (67/211) | 13-46 |
| Linear streaks | 25 (53/211) | 3-41 |
| Nodules | 20 (43/211) | 8-25 |
| Pleural thickening | 16 (33/211) | 7-28 |
| Ring shadow | 14 (19/135) | 3-23 |
| Calcified lesions | 6 (4/64) | 4-8 |
| Adenopathy | 3 (1/39) | Not available; only a single study reported on adenopathy |
| Normal | 8 (11/140) | 5-13 |
Based on data from reference 80. These studies do not include infections by P. kellicotti, as a series of patients with North American paragonimiasis has not been described. The presence of consolidation, pleural effusions, cystic lesions, linear streaking, nodules, and pleural thickening is summarized for 211 patients from four studies. Fewer studies recorded the presence of a ring shadow, a calcified lesion, adenopathy, or a normal chest radiograph; the number of patients for whom these findings were described is the denominator given for each finding. The range denotes the highest and lowest percentage of patients with a given radiologic finding from the studies where the finding was documented; the average frequency is the total number of patients with the radiologic finding divided by the total number of patients examined for the finding. A more detailed summary of the five studies has been produced by F. T. Kagawa (80).
