Atypical Radiological Findings in Patients with Hydatid Cysts of the Lung, Study of 1024 Cases
journal of cardio-thoracic medicine, 2013
A B S T R A C T Introduction: The objective of this study was to give a description of the most prominent atypical radiological presentations of lung hydatidosis. Materials and Methods: All patients diagnosed with pulmonary hydatidosis by surgical exploration were included in this study. Standard chest roentgenogram and computed tomography CT) were evaluated before surgery for lung cysts or unknown lesions. Radiological indings were divided into two categories: 1- Typical hydatid cysts that were previously presented by imaging as a hydatid cyst in the form of an intact cyst, water lily sign and crescent sign. 2- Atypical hydatid cysts that were not similar to typical previously mentioned hydatid cysts. Results: During a 26-year period, 1024 subjects with pulmonary hydatidosis were diagnosed and operated on. Chest X-rays (interpreted in 832 cases) showed perforated cysts in 190 (23%) and atypical findings such as mass, alveolar type infiltration, abscess and collapse in 113 (13%) pat...
Multiple and Bilaterally Pulmonary Hydatid Cystic Mimicking Metastatic Lesions
2017
Hydatid cyst is a parasitic infestation of the humans that caused by echinococcus infection. This infection is considerable significantly aspublic health problem. The most common locations for development of a hydatid cyst are the liver (75%) and the lung tissue (15%). Few reports from the medical literature have presented pulmonary hydatidosis which clinically mimics metastaticmalignant tumors at initial clinical finding. Because of its unusual presentation, the diagnosis may easily be missed with clinical presentations and imaging. Because of this problem, hydatid cyst of lung should be in difrienciated diagnosis of others pulmonary diseases. Case presentation: A 56 year-Old Iranian female patient presented with a 2-month history of chest pain, loss of appetite, weight loss, and dyspnea was referred to our hospital. Computed tomography of the chest and chest X-Ray shows multiple nodules in both lungs .The open surgery allowed diagnosis. The patient underwent a left anterolateral t...
Radiological manifestations of thoracic hydatid cysts: pulmonary and extrapulmonary findings
Insights into Imaging
Hydatid cyst caused by the larval form of Echinococcus is a worldwide zoonosis. The lungs and liver are the most common sites involved. While the lung parenchyma is the most common site within the thorax, it may develop in any extrapulmonary region including the pleural cavity, fissures, mediastinum, heart, vascular structures, chest wall, and diaphragm. Imaging plays a pivotal role not only in the diagnosis of hydatid cyst, but also in the visualization of the extent of involvement and complications. The aim of this pictorial review was to comprehensively describe the imaging findings of thoracic hydatid cyst including pulmonary and very unusual extrapulmonary involvements. An outline is also given for the findings of complications and differential diagnosis of thoracic hydatid cyst.
Giant viable hydatid cyst of the lung: a case report
Journal of Medical Case Reports, 2008
Introduction: Hydatid disease is a parasitic infestation caused by Echinococcus granulosus. The resulting large cysts in the lung are a special clinical entity called giant hydatid cysts. Case presentation: An 18-year-old Yemeni woman presented with a dry cough and mild fever, with no history of chest pain, dyspnoea or weight loss. Chest X-ray revealed a homogenous opacity almost replacing the right lung. The patient underwent surgery which revealed a large, viable hydatid cyst measuring 26 × 18 × 5 cm. Conclusion: This case report provides evidence that non-complicated hydatid cysts, even if very large, have a good prognosis and can be safely treated by parenchyma-preserving surgery.
Hydatid cysts of lung and axillary region mimic lung metastasis: A case repor
Journal of Research in Clinical Medicine
Hydatid cyst disease is one of the zoonoses caused by the larval stage of Echinococcus granulosus,mostly involving the liver and the lungs; but its complications can be seen in every site andorgan. Sometimes it can cause suspicious and complicated cases that mimic malignancy. Forinstance, axillary involvement of hydatid cyst is very rare. It is important to differentiate hydatidcyst disease from cancer, since it may show malignant features when pulmonary or other distantorgan involvement takes place. In this study, we present a case of multiple masses in the lungsand the axillary region in a 48-year-old woman. The ultrasonography was unable to detecthydatid cysts. Biological values were normal except for serum sodium (Na) and potassium (K);and enzyme-linked immunosorbent assay (ELISA) test was negative. Hydatid cyst was diagnosedwhile taking a biopsy from the axillary tumor.
Clinical and Radiological Profile of Pulmonary Hydatid Cysts
SAS Journal of Medicine
Original Research Article Introduction: Pulmonary hydatid cyst (KHP) is a major health problem, both in frequency and severity. Methods: To determine the epidemiological profile, the clinical and radiological aspects of KHP, we conducted a retrospective descriptive study of 184 cases identified in the respiratory diseases department of the Ibn Rochd Hospital in Casablanca between 2005 and 2019. Results: 93 women and 91 men. The average age was 38.6 years. The revealing signs were dominated by chest pain (84%). The diagnosis of pulmonary hydatidosis was based on imaging and hydatid serology. Thoracic CT was performed in 94% of cases. Bronchoscopy had visualized watery membranes in 22.3% of cases. Hydatic cyst was unique in 58% of cases, associated with liver damage in 19% of cases, heart damage and pulmonary artery in 1.6% of cases. Treatment was surgical in 70.6% of cases. The progression was good in 83% of cases. Conclusion: Hydatid disease is characterized by clinical polymorphism. Chest X-ray is often sufficient to make the diagnosis, while chest CT is still the choice for complicated cysts.
Hydatid cyst masquerading as empyema leading to benign pulmonary neoplasm: A diagnostic challenge
Medical science, 2023
Hydatid cyst (HC) is a disease that occurs due to the parasite Echinococcus (EC) and the most typical infection in humans with hydatid disease is caused by the species granulosus. The most frequent site for cyst development is the liver, followed by the lung which is the second most common location. Therefore, this case report highlights a case of a 75-year-old male who presented with chief complaints of left-sided chest pain, dyspnoea, cough and mucoid expectoration since one month and was initially thought as empyema. A diagnostic assessment was performed involving computed tomography suggested possibility of a hydatid cyst. Serological tests positive for Echinococcus granulosus. The treatment parameters involved both surgical and medical approaches. Thoracotomy was performed along with the postoperative medical treatment that mainly involved antihelminthics (Albendazole) and patient recovered well with treatment. This report highlights that large hydatid cysts can be surgically removed with good outcomes and the importance of realizing that the disease is a burden to public health and is much neglected.

Hydatidosis is caused by Echinococcus granulosus. Humans may be infected incidentally as intermediate host by the accidental consumption of soil, water, or food contaminated by fecal matter of an infected animal. Hydatidosis is one of the most symptomatic parasitic infections in various livestock-raising countries. Lung is the second most commonly affected organ following the liver. The symptoms depend on the size and site of the lesion. It can present as an asymptomatic pulmonary lesion to hemoptysis, chest pain, coughing anaphylaxis, and shock. There are very few reported cases of isolated lung hydatidosis without exposure to animals or nonvegetarian diet. For hydatidosis, serology and imaging are diagnostic tools. Surgical removal and/or chemotherapy are the mainstay of treatment. Here, we discuss a case of persistent left lower lobe cystic lesion in young female with a history of operated left breast carcinoma which was thought to be of metastatic lesion but ultimately confirmed as pulmonary hydatid cyst after unintended aspiration of cystic fluid to rule out malignancy. Pulmonary hydatidosis should always be considered as a differential diagnosis when dealing with a cystic lesion on radiology.
Complications of Hydatid Cysts in the Lung
A hydatid cyst, or echinococcus, is a zoonosis frequently formed by the larvas of Echinococcus granulosus. The disease appears as a slowly growing cystic mass and is asymptomatic. The disease is common in the Eastern, Southeastern, and Central Anatolia regions of Turkey. The rate of incidence of the disease in Turkey is reported as 5.7 out of 100,000 individuals. The complications of hydatic cysts appear as different clinical entities depending on the cyst's being intact or ruptured. The complications of intact cysts are usually compression symptoms, while the infection in the clinical progress of the ruptured cysts and secondary complications to the infecion are frequently seen. In this section, hydatid cyst complications in the lung, extrapulmonary thoracic findings, and respiratory system complications of hydatid cyst cases of the liver will be discussed.
