Pulmonary schistosomiasis - imaging features.

Area of Science:

• Tropical medicine
• Parasitology
• Radiology

Background:

• Schistosomiasis is a prevalent helminthic infection in tropical and subtropical regions.
• Pulmonary involvement in schistosomiasis presents as either acute or chronic compromise.
• Chronic infection can lead to pulmonary hypertension and cor pulmonale due to granuloma formation and fibrosis.

Purpose of the Study:

• To describe the pulmonary manifestations of schistosomiasis.
• To discuss the typical imaging findings in acute and chronic pulmonary schistosomiasis.
• To present a case study of pulmonary schistosomiasis.

Main Methods:

• Review of literature on schistosomiasis and pulmonary involvement.
• Analysis of imaging findings (CT scans) in acute and chronic schistosomiasis.
• Case presentation of a patient with pulmonary schistosomiasis.

Main Results:

• Acute pulmonary schistosomiasis commonly presents with small pulmonary nodules (2-15 mm) and larger nodules with ground-glass opacities on CT.
• Chronic schistosomiasis can lead to significant lung pathology, including obliterative arteriolitis and pulmonary hypertension.
• Katayama fever is a severe clinical manifestation of acute schistosomiasis.

Conclusions:

• Pulmonary schistosomiasis has distinct imaging features in its acute and chronic forms.
• Radiological findings are crucial for diagnosing pulmonary schistosomiasis.
• Understanding these patterns aids in managing patients with this parasitic infection.
