ICD-10: B67.1

Echinococcus granulosus infection of the lung, classified under ICD-10 code B67.1, is a specific type of echinococcosis caused by the parasitic tapeworm Echinococcus granulosus. This infection primarily affects the lungs but can also involve other organs, leading to a range of clinical manifestations.

Clinical Description

Pathophysiology

Echinococcus granulosus is a cestode (tapeworm) that typically resides in the intestines of definitive hosts, such as dogs and other canids. The life cycle involves the shedding of eggs in the feces of these hosts, which can then be ingested by intermediate hosts, including humans. Once ingested, the eggs hatch in the intestines, releasing larvae that penetrate the intestinal wall and migrate to various organs, most commonly the liver and lungs, where they form cysts.

Symptoms

The clinical presentation of Echinococcus granulosus infection in the lungs can vary significantly depending on the size and location of the cysts. Common symptoms include:

• Cough: Often persistent and may be productive.
• Chest Pain: Can be localized or diffuse, depending on the cyst's location.
• Hemoptysis: Coughing up blood may occur if the cyst ruptures into the bronchial tree.
• Dyspnea: Shortness of breath can result from cysts occupying lung space or causing pleural effusion.
• Fever and Chills: These may occur, particularly if there is secondary infection or rupture of the cyst.

Diagnosis

Diagnosis typically involves a combination of clinical evaluation, imaging studies, and serological tests. Key diagnostic methods include:

• Imaging: Chest X-rays and CT scans are crucial for visualizing cysts in the lungs. CT scans are particularly effective in assessing the size, number, and location of cysts.
• Serological Tests: Blood tests can detect specific antibodies against Echinococcus granulosus, aiding in diagnosis.
• Histopathological Examination: In some cases, tissue samples may be analyzed to confirm the presence of the parasite.

Complications

Complications can arise from untreated infections, including:

• Cyst Rupture: This can lead to anaphylactic shock or secondary infections.
• Pulmonary Abscess: Secondary bacterial infections may develop.
• Pleural Effusion: Accumulation of fluid in the pleural space can occur.

Treatment

The management of Echinococcus granulosus infection of the lung typically involves:

• Surgical Intervention: Surgical removal of cysts is often necessary, especially in cases of large or symptomatic cysts.
• Medical Therapy: Antiparasitic medications, such as albendazole or mebendazole, may be used as adjunct therapy, particularly in inoperable cases or to reduce cyst size preoperatively.
