Amoebic lung abscess is caused by an infection of the lungs by the parasite Entamoeba histolytica. This parasite is found in contaminated water and food, and is spread through the air when an infected person coughs or sneezes.
The diagnosis of amoebic lung abscess is usually made based on the patient’s symptoms, physical examination, and results of chest x-rays and sputum tests. Other tests, such as computed tomography (CT) scans and bronchoscopy, may also be necessary to confirm the diagnosis.
The differential diagnosis of amoebic lung abscess includes other types of infection, including bacterial pneumonia, tuberculosis, and fungal infections. It is important to rule out these other conditions before making a diagnosis of amoebic lung abscess.
Treatment for amoebic lung abscess typically involves antibiotics to kill the parasite, as well as supportive care to relieve symptoms. In severe cases, surgery may be necessary to drain the abscess.
The prognosis for amoebic lung abscess is generally good with prompt treatment. Most patients recover fully with appropriate treatment. Without prompt treatment, however, the infection can spread and cause serious complications, such as lung damage or death.
