Abstract
A 37-year-old woman presented to our hospital with mild abdominal pain experienced for 2 months and hepatic nodules in segments 3 and 8. Peripheral blood eosinophilia was observed, and toxocariasis was serologically diagnosed. Seventeen days after the first imaging evaluation, a new lesion was found in segment 9 of the right lung, which was contiguous through the diaphragm to the hepatic nodule in segment 8. After treatment with albendazole, the liver and lung nodules disappeared. We suspect that larvae had directly invaded the lung from the liver, through the diaphragm.

Abstract
The prognosis of pulmonary toxoplasmosis, including disseminated toxoplasmosis involving the lungs, following hematopoietic stem cell transplantation (HSCT) is extremely poor due to the difficulties associated with early diagnosis and the rapidly progressive deterioration of multiorgan function. In our institution, we identified nine cases of toxoplasmosis, representing incidences of 2.2 and 19.6 % among all HSCT recipients and seropositive HSCT recipients, respectively. Of the patients with toxoplasmosis, six had pulmonary toxoplasmosis. Chest computed tomography (CT) findings revealed centrilobular, patchy ground-glass opacities (n = 3), diffuse ground-glass opacities (n = 2), ground-glass opacities with septal thickening (n = 1), and marked pleural effusion (n = 1). All cases died, except for one with suspected pulmonary toxoplasmosis who was diagnosed by a polymerase chain reaction assay 2 days after the onset of symptoms. In pulmonary toxoplasmosis, CT findings are non-specific and may mimic pulmonary congestion, atypical pneumonia, viral pneumonitis, and bronchopneumonia. Early diagnosis and treatment is crucial for overcoming this serious infectious complication. Pulmonary toxoplasmosis should be considered during differential diagnosis in a recipient with otherwise unexplained signs of infection and CT findings with ground-glass opacities, regardless of the distribution.

Abstract
INTRODUCTION Toxocariasis is a parasitosis which complicates the accidental infestation of the humans by larvae of a roundworms belonging of the genus Toxocara. In adults, the discovery is often incidental during a hypereosinophilia check-up. Clinical signs are not specific and depend on affected organs. CASE REPORT We report the case of a 53-year-old-woman who has consulted for a recent cough, after spontaneous resolution of abdominal pain. The laboratory examination isolated an hypereosinophilia and the liver sonography showed two hypoechogenic nodules. The CT-scan found bilateral lung nodules with ground glass halo. Broncho-alveolar lavage identified an eosinophilic alveolitis. Positive serologic results for toxocariasis and western blot results allowed to conclude to the diagnosis of pulmonary and hepatic toxocariasis. CONCLUSION Although rare, pulmonary toxocariasis should be suspect in any lung eosinophilia, especially if the patient has never traveled.

Abstract
A 38-year-old woman with sustained right chest pain was referred to our hospital. She showed pleural effusion and peripheral blood eosinophilia. Thoracentesis revealed eosinophilic pleural effusion in which the smear, culture and cytological examinations were all negative. Although she had no notable dietary history, chest CT revealed linear opacities, which suggested the migration tracks of paragonimiasis. The diagnosis was confirmed using enzyme-linked immunosorbent assays, which showed elevated Paragonimus westermani and Paragonimus miyazakii antibody levels. After the initiation of praziquantel therapy, all clinical findings were promptly improved. The detection of a migration track may therefore be useful in the diagnosis of paragonimiasis.

Abstract
Solitary pulmonary nodules are a common finding on chest radiography and CT. We present the case of an asymptomatic 59-year-old male found to have a 13 mm left upper lobe nodule on CT scan. The patient was asymptomatic and the CT was performed to follow up mediastinal and hilar lymphadenopathy that had been stable on several previous CT scans. He had a history of emphysema and reported a 15 pack-year smoking history. PET-CT was performed which demonstrated mild 18-FDG uptake within the nodule. Given his age and smoking history, malignancy was a consideration and he underwent a wedge resection. Pathological examination revealed a necrobiotic granulomatous nodule with a central thrombosed artery containing a parasitic worm with internal longitudinal ridges and abundant somatic muscle, consistent with pulmonary dirofilariasis. Dirofilaria immitis, commonly known as the canine heartworm, rarely affects humans. On occasion it can be transmitted to a human host by a mosquito bite. There are two major clinical syndromes in humans: pulmonary dirofilariasis and subcutaneous dirofilariasis. In the pulmonary form, the injected larvae die before becoming fully mature and become lodged in the pulmonary arteries.

Abstract
BACKGROUND/AIMS Pleuropulmonary paragonimiasis produces no specific symptoms or radiologic findings, allowing for the possibility of misdiagnosis. We evaluated the specific clinical and pleural fluid features of pleuropulmonary paragonimiasis masquerading as pleural tuberculosis. METHODS We retrospectively analyzed the clinical and radiologic characteristics of 20 patients diagnosed with pleuropulmonary paragonimiasis between 2001 and 2011. RESULTS In total, 17 patients presented with respiratory symptoms, including dyspnea (30%), hemoptysis (20%), cough (20%), and pleuritic chest pain (15%). Chest radiographs revealed intrapulmonary parenchymal lesions, including air-space consolidation (30%), nodular opacities (20%), cystic lesions (15%), ground-glass opacities (10%), and pneumothorax (5%). A pleural fluid examination revealed eosinophilia, low glucose levels, and high lactate dehydrogenase (LDH) levels in 87%, 76%, and 88% of the patients, respectively. These traits helped to distinguish pleuropulmonary paragonimiasis from other pleural diseases such as parapneumonic effusion, malignancy, and pleural tuberculosis. CONCLUSIONS Pleuropulmonary paragonimiasis is often initially misdiagnosed as other pleural diseases. Therefore, it is important to establish the correct diagnosis. In patients with unexplained pleural effusion living in paragonimiasis-endemic areas, pleural fluid obtained by thoracentesis should be examined to distinguish pleuropulmonary paragonimiasis. When marked eosinophilia, high LDH levels, and low glucose levels are identified in pleural fluid, physicians could consider a diagnosis of pleuropulmonary paragonimiasis.

Abstract
Paragonimiasis is a food-borne zoonosis caused by a trematode of the genus Paragonimus(1,2). Infestation is rare in Spain, but the influx of people from endemic areas should make us keep this condition in the differential diagnosis of our patients(2,5). We report the case a patient from Ecuador and resident in Spain for 7 years with active pulmonary tuberculosis on arrival in Spain and later diagnosed with of pulmonary paragonimiasis due to persistent haemoptysis. The diagnosis was established by surgical lung specimen showing granulomas containing parasite eggs and the macroscopic view of the fluke within a lung cavity. Initial tuberculosis treatment and current treatment with praziquantel controlled both conditions.

Abstract
We compared the chest radiographic findings of patients with pulmonary paragonimiasis in the Lao People's Democratic Republic (PDR) with a report from Korea. The clinical and radiological characteristics of 50 confirmed Laotian pleuropulmonary paragonimiasis patients were studied between March 2003 and June 2007. In 49 patients, the chest radiographs showed abnormal findings (98%). Pulmonary parenchymal abnormalities were found in all 49 patients, whereas pleural effusion was only found in 11 patients (22%). The three most common intraparenchymal findings were multiple small cysts (90%), irregular linear densities (68%), and nodular opacities (40%). The numbers of patients who had these three findings were significantly different from the Korean report (P < 0.001). In conclusion, radiographic findings of pulmonary paragonimiasis may vary among countries.

Abstract
Paragonimiasis is a zoonosis affecting wild and domestic animals and human beings, caused by species of trematodes of the genus Paragonimus. Humans become infected after ingestion of raw or poorly cooked fresh water crustaceans. The aim of the present work is the description of a case of a 3-years old child, coming from Guárico State in Venezuela with a year of residence in the seashore of the Provincia Manabí in Ecuador, where he ate crabs in "ceviche". During hospitalization, he presented respiratory distress, hepatomegaly and nodules in the back. The thorax cat scan showed heavy infiltrate in both pulmonary bases and pleural compromise. Based on clinic, radiological images, an eosinophilia of 47% (Eosinophils absolute count (EAC) 6.682/mm3) and the antecedent of raw crabs ingestion, pulmonary paragonimiasis was diagnosed. Paragonimus eggs were not found in sputum and feces. ELISA with crude Paragonimus antigen was positive and Western blot revealed recognition of specific molecules. After treatment for three days with Praziquantel at a daily dose of 25 mg/kg body weight divided into three intakes, the sintomatology disappeared and radiological images and number of eosinophils diminished considerably.

Abstract
Pulmonary capillariasis is a zoonotic disease caused by the cosmopolitan nematode Capillaria aerophila, which circulates among wild carnivorous and omnivorous mammals. Only 11 cases have been documented to date. We describe a cryptic case of pulmonary capillariasis in a Serbian woman that resembled a bronchial carcinoma.

Abstract
Babesiosis is a tick-borne illness caused by the protozoan Babesia microti. Most patients are asymptomatic but the infection may produce a spectrum of symptoms in immunocomprimised patients, especially asplenic patients. These range from mild fever, sweats, fatigue, and myalgias to severe multiorgan failure, including acute respiratory distress syndrome and death. Radiographic appearances include bilateral patchy air space and interstitial opacities. We report the radiographic, high-resolution computed tomography (HRCT), and hematologic appearances in a 63-year-old man presenting with acute babesisois. HRCT images revealed smooth septal thickening and intralobular lines superimposed on ground glass opacities in both upper lobes. Follow-up HRCT after 2 weeks of therapy demonstrated resolution of the pulmonary parenchymal abnormalities.

Abstract
In the northeastern region of India, paragonimiasis is emerging as an important public health problem. However, until now the identity of the species causing human infection has been uncertain and there has been little information on the prevalence and clinicoradiological features of infection in the community. Parasitological and immunological surveys revealed that paragonimiasis was hyperendemic in parts of Arunachal Pradesh. Egg positivity in the sputum was 20.9% and 4.1% in children (age </=15 years) and adults (age >15 years), respectively. Antibody positivity against excretory-secretory antigen of the adult worm in children and adults was 51.7% and 18.7%, respectively. Chronic cough (97.2%) and haemoptysis (83.3%) were common respiratory symptoms among egg-positive cases. Chest radiography (n=68) images from egg-positive cases showed that air space consolidation (75%), cavitary lesions (14.7%) and mediastinal adenopathy (11.8%) were very frequent. Less frequent findings were nodular lesions, bronchiectasis, mediastinal adenopathy, pleural thickening and pleural effusion. DNA extracted from eggs from the sputum of patients from Arunachal Pradesh was sequenced. Analyses of the second internal transcribed spacer (ITS2) of nuclear rDNA revealed that the species responsible is Paragonimus heterotremus.

Abstract
OBJECTIVE To retrospectively evaluate the computed tomography (CT) findings of pulmonary involvement in patients with visceral larva migrans caused by Ascaris suum. METHODS Institutional review board approval was obtained, and informed consent was waived. Chest CT scans obtained between January 1994 and November 2005 in 32 patients infected with A. suum were retrospectively evaluated by 3 chest radiologists. In 4 patients who underwent surgical or transbronchial biopsy, comparisons of the CT images with the actual specimens were performed. RESULTS On CT scans, abnormal findings were seen in 28 patients. The most common abnormality consisted of nodules (n = 19) in which the majority had a halo of ground-glass attenuation (n = 17), followed by ground-glass attenuation (n = 18), and interlobular septal thickening (n = 14). These abnormalities were predominantly seen in the peripheral lung (n = 25). Of the 7 patients who underwent follow-up CT scans, nodules (n = 6) and ground-glass attenuation (n = 5) had migrated in 4 patients. Pathologically, these findings corresponded to marked eosinophilic infiltration into the interstitium. CONCLUSIONS These CT findings are considered to be suggestive of thoracic involvement in patients with visceral larva migrans caused by A. suum.

Abstract
The authors aim to report the chest CT findings of a patient with disseminated cysticercosis, emphasising the pulmonary and cardiac features. The main finding consisted of multiple pulmonary, cardiac and chest wall nodules. The present case demonstrates that cysticercosis should be considered in the differential diagnosis of multiple pulmonary nodules, mainly in those patients with similar lesions in the cardiac muscle and/or in the chest wall.

Abstract
Reported herein is a 57-year-old man infected by Sparganum mansoni, a kind of tapeworm, showing a solitary nodule of the middle lobe of the right lung. Because a transbronchial biopsy could not diagnose the nodule, a right middle lobectomy was performed on suspicion of malignant tumor. The lesion was diagnosed as sparganosis by histological and immuno-serological examinations. Histological examination revealed granulomatous inflammation with neutrophil and eosinophil infiltration around the worm and interstitial pneumonia surrounding the nodule. Moreover, vasculitis with foreign body giant cell was seen around the lesion. To the authors' knowledge this is the second case of sparganosis limited in the lung, and the current report presents the first detailed histological description of a pulmonary sparganosis case.

Abstract
Immunocompromised patients are susceptible to infections by a wide range of organisms. In the past several decades, AIDS epidemic, advances in the treatment of cancer, organ transplantation, and immunosuppressive therapy have resulted in large numbers of patients who develop abnormalities in their immune system. Moreover, mildly impaired host immunity as it occurs in chronic debilitating illness, diabetes mellitus, malnutrition, alcoholism, advanced age, prolonged corticosteroid administration, and chronic obstructive lung disease have also been regarded as predisposing factors of pulmonary infections. Imaging plays a crucial role in the detection and management of patients with pulmonary infectious diseases. When pulmonary infection is suspected, knowledge of the varied radiographic manifestations will narrow the differential diagnosis, helping to direct additional diagnostic measures, and serving as an ideal tool for follow-up examinations. Combination of pattern recognition with knowledge of the clinical setting is the best approach to pulmonary infection occurring in the immunocompromised patients.

Abstract
A 32-year-old male was presented with massive haemoptysis. An urgent chest X-ray (Fig. 1a) and CT chest (Fig. 1b-e) was done revealing a right lower lobe consolidation collapse. An urgent rigid bronchoscopy was performed to localize the source of bleeding and try to control it. A right lower lobectomy was done using a double-lumen endotracheal tube. Preoperative and intraoperative impressions of non-specific inflammation were accused to be the aetiology. Histopathology revealed pulmonary venous congestion with bilharsial ova.

Abstract
OBJECTIVE The objective of our study was to evaluate chest radiographic and CT findings of patients with pulmonary lesions associated with visceral larva migrans due to Ascaris suum or Toxocara canis. CT investigation was focused on the location, size, contour, and internal features of the lesions; migration of lesions; mediastinal lymphadenopathy; and pleural effusion. CONCLUSION Pulmonary visceral larva migrans appears on CT as multifocal subpleural nodules with halo or ground-glass opacities and ill-defined margins.

Abstract
OBJECTIVE We describe the findings of unenhanced chest CT in 10 patients with acute schistosomiasis. CONCLUSION Despite the absence of pulmonary symptoms in four individuals, all patients had parenchymal abnormalities. Small pulmonary nodules were the most common finding, identified in nine patients. These nodules ranged in size from 2 to 5 mm in five patients, with larger nodules ranging up to 15 mm seen in four patients. In one patient, the only parenchymal abnormality was a single 5-mm focus of ground-glass attenuation. No relationship was seen between either the presence of pulmonary symptoms or the presence of peripheral eosinophilia and the severity of parenchymal disease. No additional significant findings were identified.

Abstract
A 48-year-old man was admitted with an abnormal shadow on a chest X ray. Chest X ray and CT revealed a solitary nodule in the right lung field. Mycobacterium gordonae was cultured from sputum. Tumorectomy by video-assisted thoracoscopic surgery was done for histological diagnosis, and Dirofilaria worms accompanied with epithelioid cell granuloma with necrosis were found, while no bacteria were cultured from biopsy specimen, thus we diagnosed dirofilariasis. Because a solitary nodule can be caused by either Dirofilaria species or nontuberculous mycobacteria, this case was of interest with regard to the differential diagnosis of a lung solitary nodule.

Abstract
A 47-year-old man presented with bloody sputum and a cavitary mass shadow was formed in his right middle lobe. Transbronchial lung biopsy revealed the presence of parasite eggs and eosinophil infiltration. Based on the positive reaction against Westermani Paragonimus by multiple dot ELISA, Westermani Paragonimiasis was diagnosed. The cavitary mass shadow disappeared after the treatment with Pragiquantel. This is a rare case of Westermani Paragonimiasis showing interesting changes of chest CT findings during its clinical course.

Abstract
OBJECTIVE The purpose of our study was to identify any specific CT features that may help in the diagnosis of pleuropulmonary paragonimiasis. CONCLUSION Pleuropulmonary paragonimiasis usually manifests as a subpleural or subfissural nodule of about 2 cm in diameter that frequently contains a necrotic low-attenuation area. The constellation of focal pleural thickening and subpleural linear opacities leading to a necrotic peripheral pulmonary nodule is another frequent CT finding of paragonimiasis. Although minimal and easily overlooked, focal fibrotic pleural thickening adjacent to a pulmonary nodule can be an important clue in the diagnosis of pleuropulmonary paragonimiasis on CT.

Abstract
Infection by the cat lungworm Aelurostrongylus abstrusus is considered uncommon. Here, the authors report the clinical, diagnostic and therapeutic features of five infections recently observed in Italy. All cats were under 12 months of age. All except one cat had symptomatic infections, with cough, dyspnea, and weight loss with radiographic signs of broncopneumonia. All cats were eosinophilic. Larvae were present in fresh fecal smears and on flotation exam in all cats. Baermann larval recovery permitted definitive identification and, in one case, larvae per gram of feces (lpg) counts. One dose of ivermectin (400 microg/kg) was not effective in one cat, while one dose of selamectin (6 mg/kg) was effective in one of three cases and fenbendazole at 50 mg/kg given daily for 15 days was effective in four of four cases.

Abstract
Paragonimiasis westermani, or Oriental lung fluke, is a common parasitic zoonosis, which is acquired from eating the flesh of wild boar or freshwater crabs. After being ingested by humans, the larvae of P. westermani migrate across small intestinal mucosa into the intra-abdominal space, and then finally into to the pleural space and lung parenchyma. High-resolution CT findings of P. westermani consist of worm cysts, migration track, peripheral density, bronchial wall thickening, and centrilobular nodules, which prompt serological tests and detection of eggs in sputum or BAL fluid for definitive diagnosis.

Abstract
OBJECTIVE The purpose of this study was to describe the computed tomography (CT) and pathologic features of 5 nodules of pulmonary dirofilariasis in 4 patients. METHODS Four patients with 5 nodules of pathologically confirmed pulmonary dirofilariasis who under went CT were enrolled, and the imaging interpretations were retrospectively compared with the histopathologic characteristics. RESULTS Three of the 4 patients had a solitary nodule, and the remaining patient had 2 nodules. All the nodules were distributed in the right lower lobe and were attached to the pleura. They were all round or oval in shape and ranged in size from 11 to 22 mm in largest diameter (mean=17 mm). On thinner section CT, the nodules had a well-defined smooth margin with or without a shallow notch; they were connected to the arterial branch and, occasionally, to the venous branch. On contrast-enhanced CT, all the nodules contained a homogeneous low-attenuation area, which corresponded to areas of coagulative necrosis on histopathologic examination. CONCLUSION Although the CT findings of a pulmonary dirofilariasis nodule are nonspecific, awareness of the findings on contrast-enhanced CT and the pathologic appearance of this rare benign condition may facilitate its differentiation from a malignant nodule.

Abstract
A 16-year-old female patient, who had undergone bone marrow transplantation 35 days earlier, presented with dry cough, dyspnea, and fever for 4 days. Chest radiography showed poorly-defined bilateral opacities. High-resolution CT revealed bilateral ground glass opacities with superimposed septal thickening and intralobular linear opacities. Laboratory results were nonspecific and empiric treatment with multiple drugs was initiated. The patient had no response to therapy and died 12 days after the admission. At autopsy the patient had disseminated toxoplasmosis with involvement of the central nervous system, myocardium, bone marrow, and lungs.

Abstract
A 59-year-old man with rusty-colored sputum was admitted for evaluation of a nodular shadow on his chest radiograph. Chest computed tomography (CT) revealed nodules and nodular opacities with a cavity in the right S3. Chest CT also showed clearly a double linear shadow other than the bronchovascular bundle, with a different course from that of the bronchovascular bundle, suggesting a worm migration track. The diagnosis of paragonimiasis westermani was confirmed by detection of Paragonimus eggs in a bronchoscopic aspirate smear and by immunoserological examination. The linear lesion on the chest CT is uncommon in paragonimiasis, but the finding is thought to be useful for the diagnosis of this disease.

Abstract
The case of a 48-year-old man with pulmonary paragonimiasis mimicking lung cancer on positron emission tomography with fluorodeoxyglucose (FDG-PET) imaging is reported herein. Plain radiography and computed tomography (CT) of the chest showed a nodular lesion at the left pulmonary hilum. Lung cancer was strongly suggested from standardized uptake values determined on FDG-PET imaging; however, repeat chest CT revealed the lesion to have decreased in size. Pulmonary paragonimiasis was subsequently diagnosed after sputum microscopy demonstrated operculated parasitic eggs. To the best of our knowledge, this is the first reported case of pulmonary paragonimiasis mimicking lung cancer on FDG-PET imaging.

Abstract
A 59-year-old woman suffering from chronic lymphocytic leukemia developed pulmonary lesions; bronchoalveolar lavage was performed for possible systemic fungal infection. However, direct microscopic analysis revealed ciliated protozoa identified as Balantidium coli. B. coli is the only known pathogenic ciliate, and is usually associated with intestinal infection in areas associated with pig rearing. On very rare occasions the organisms may invade extra-intestinal organs, in this case the lungs of an immunocompromised patient. This case is unusual as balantidiasis is rare in Europe, the patient had no obvious contact with pigs, and there was no history of diarrhea prior to pulmonary colonization. Metronidazole was rapidly administered, and the condition improved after 24-48 hr.

Abstract
The diagnosis of tuberculosis by X-ray radiogram is often confused with pulmonary carcinoma, bacillary and parasitic infections, and chronic mycosis. A case of pulmonary paragonimiasis misdiagnosed as tuberculosis by X-ray radiogram is reported. With this case, the smears of sputum were rechecked by an inspection technician's discernment, and Paragonimus eggs along with numerous eosinophils and Charcot-Leyden crystals were detected. In suspected cases of tuberculosis, a history of crab-eating plus sputum examinations, image findings, and serodiagnosis are necessary to rule out paragonimiasis.

Abstract
Acute pulmonary schistosomiasis occurs in non-immune hosts, particularly visitors to regions where Schistosoma species are endemic. While radiological findings of acute pulmonary schistosomiasis might resemble neoplastic or granulomatous disease, an appropriate travel history might suggest the diagnosis. With rising popularity of travel to Africa and South-East Asia, the incidence of acute pulmonary schistosomiasis can be expected to increase. We describe a case of acute pulmonary schistosomiasis occurring in an Australian returning from Lake Malawi, Sub-Saharan Africa.

Abstract
Pulmonary dirofilariasis (PD), caused by Dirofilaria immitis (D. immitis), the dog heartworm, is not common in humans, though we recently encountered 4 cases. Chest X-ray images from annual health examinations showed a single spherical nodule in the inferior or middle portion of the right lung in each patient. None of the patients showed any clinical symptoms and had no contact with dogs. Hematological results in 3 of the cases were within normal limits, while mild eosinophilia was found in one. Serological tests for the Anti-Dirofilaria antibodies were not performed. There were no characteristic clinical manifestation of PD in any of the patients, however, we consider it important to keep a diagnosis of PD in mind, when we experienced these cases, they present no characteristic clinical manifestations. Pathologically, macroscopic findings showed well-circumscribed nodules that were round peripheral lesions in lungs. Histological results revealed coagulation necrosis with fibrosis and granulation in the nodule edge, which contained inflammatory cells. By means of silver staining, the worm structures in the nodules could be identified well, and the quadrant cells in the sections were numbered about 30. Immunohistochemically, the somatic muscle tissues were stained with anti-Dirofilaria antibody. These findings indicated that the pulmonary lesions in all 4 cases were due to D. immitis.

Abstract
Paragonimiasis is an important cause of pulmonary disease worldwide. It results from an infection with Paragonimus, a parasite that reproduces through a complex life cycle involving snails, crustaceans, and mammals. Humans acquire the disease by ingesting uncooked freshwater crab or crayfish. Paragonimus species are distributed globally, and the disease is well known in endemic regions of Asia where culturally based methods of food preparation foster human transmission. Paragonimus also exists in regions of the United States but has been a rare cause of pulmonary disease. We report a case of a previously healthy young man who developed a dense empyema from Paragonimus kellicotti that ultimately required thoracotomy and praziquantel to eradicate his infection.

Abstract
We describe the case of a 30-year-old asymptomatic farmer who underwent a pulmonary segmentectomy due to the casual finding of a pulmonary nodule in preoperative chest radiography. As bronchoscopic samples rule out mycobacterium infection and malignancy, surgery could have been avoided with the use of serological tests and radiographic follow-up based on epidemiology of dirofilariasis in our country.
