Lung fluke, Paragonimus westermani of Paragonimus species usually are accompanied by a persistent cough, hemoptysis, and chest pain. Extrapulmonary paragonimiasis caused by ectopic parasites in aberrant locations such as the abdominal wall, abdominal organs, and brain has been reported and the most commonly involved extrapulmonary organ is the brain. We present a case of 56-year-old male patient with intra-abdominal paragonimiasis who underwent laparoscopic excision of abdominal granuloma caused by parasite infection. An intra-abdominal mass associated with eosinophilia might be related to parasite infection. A laparoscopic approach is the most appropriate treatment modality in such benign abdominal pathology.
[Show abstract][Hide abstract] ABSTRACT: Paragonimiasis typically results from the consumption of raw or improperly cooked crustacea, especially crabs and crayfish. Although previously endemic in Korea, the prevalence of this disease decreased in the early 1970s because of educational campaigns and fewer intermediate hosts as a result of ecological changes. Recently, we were presented with a family where all members were infected with Paragonimus after ingestion of Kejang (= drunken crab). The mother was hospitalized for general myalgia and weakness first, followed by the father, who was hospitalized for dyspnea 2 month later. After the parents were diagnosed with paragonimiasis, we recommended their daughter to visit our hospital for a checkup, because they all had eaten freshwater crabs soaked in soybean sauce. She complained of generalized myalgia, fever, and pleuritic pain, and was also diagnosed with paragonimiasis. Peripheral blood of the 3 patients revealed hypereosinophilia, and computed tomography (CT) scans of their chests showed pleural effusion. The results of antibody tests by ELISA were positive for paragonimiasis. We report here the case series of familial paragonimiasis in a modern urban city, rather than in a typical endemic area.

[Show abstract][Hide abstract] ABSTRACT: The purpose of this study was to characterize the chest CT findings of North American paragonimiasis due to Paragonimus kellicotti in the largest (to our knowledge) case series reported to date and to compare the findings with those reported for paragonimiasis infections in other regions.
A retrospective review was performed of chest CT examinations of eight patients with North American paragonimiasis treated at our institution between 2006 and 2010. Findings were characterized by site of involvement, including lungs and pleura, heart and pericardium, lymph nodes, and upper abdomen.
The most common chest CT findings in this case series were pleural effusions and internal mammary and cardiophrenic lymphadenopathy. Pulmonary parenchymal findings included peripheral lung nodules of 1-3.5 cm in size with surrounding ground-glass opacity; many nodules had a linear track to the pleural surface that may correspond to the worm's burrow tunnel. Pericardial involvement (5/8 patients) and omental inflammation (5/7 patients), which are uncommon in Asian paragonimiasis, were common in this series.
Pleural and pulmonary features of North American paragonimiasis are generally similar to those reported from Asia. The presence of a track between a pulmonary nodule and the pleura may help distinguish paragonimiasis from mimickers, including chronic eosinophilic pneumonia, tuberculosis, fungal infection, or malignancy. Pericarditis, lymphadenopathy, and omental inflammation were more common in our series than in reports on paragonimiasis from other regions. These differences may be related to the infecting parasite species or to the fact that radiologic examinations in the present series were performed relatively early in the course of infection.
