Paediatric pulmonary echinococcosis: A neglected disease

Pediatric Cystic Echinococcosis in Tehran, Iran: A 9-Year Retrospective Epidemiological and Clinical Survey of Hospitalized Cases

Cystic echinococcosis (CE), the second most significant foodborne parasitic disease worldwide, poses a significant global health burden. Understanding its clinical and laboratory features is crucial for effective management. This study aimed to investigate the epidemiological, laboratory, and clinical characteristics of pediatric CE in an Iranian referral hospital. A cross-sectional study reviewed hospital records of patients with CE admitted to Children's Medical Center, Tehran, Iran, from 2011 to 2020. Data on demographics, diagnostics, clinical presentation, laboratory findings, and treatment were collected and analyzed. A total of 114 patients, with a mean age of 7.33 ± 2.9 years, were diagnosed with CE. The male-to-female ratio was 1.78, and 73.7% were urban residents. Abdominal pain (69%) and coughing (65%) were the most common symptoms. In confirming the cyst involvement across anatomical sites, pathology emerged as the most reliable method, with effectiveness ranging from 95% to 100%. Abdominal ultrasonography and computed tomography scan were frequently utilized imaging modalities, displaying effectiveness percentages of 71-85%. Liver and lung involvement predominated (66%), with 39% of cases showing multiorgan involvement. Spleen involvement was less common (6%), and neurological involvement was rare (1-2%). The majority of patients (n = 63, 67.7%) displayed cysts larger than 50 mm. All patients received albendazole treatment, and 104 patients (91.2%) underwent surgical procedures, with three postsurgical deaths. In conclusion, hospital records over 9 years indicate an increasing prevalence of CE, emphasizing the need for heightened awareness and effective public health interventions to control this parasitic infection.

A Very Rare Cause of Dyspnea in a Child: A Hydatid Cyst From Echinococcus

Hydatid cyst is a human parasitic disease caused by echinococcus granulosus that affects mainly the liver or the lungs but may be found in any organ, including the heart in up to 2% of the cases. Humans are infected as accidental hosts by contaminated vegetables or water and by contact with saliva from infected animals. Although cardiac echinococcosis can be fatal, it is rare and often asymptomatic in the early stage. We present the case of a young boy living on a farm who suffered from mild exertional dyspnea. He suffered from pulmonary and cardiac echinococcosis and was treated surgically through median sternotomy to prevent potential cystic rupture.

Pulmonary cystic echinococcosis in a child

This case report describes the presentation, diagnosis, and treatment of a 13-year-old boy with pulmonary cystic echinococcosis. The patient presented with low-volume hemoptysis, and lung imaging revealed a large cystic mass, as well as smaller pseudo-nodular lesions, suggesting a large intrathoracic hydatid cyst and ruptured cysts. The diagnosis was confirmed by a positive echinococcosis Western Blot assay, despite equivocal serology. The treatment consisted of surgical removal of the large cyst using thoracoscopy, along with a two-week course of albendazole and praziquantel, followed by albendazole alone for two years. Analysis of the cyst membrane revealed an Echinococcus granulosus protoscolex. The patient had a successful recovery.
