Diagnosis With Brief Discussion
- Diagnosis
- Pulmonary edema in Malaria (P.vivax)
- Radiologic Findings
- The initial chest PA shows diffuse ground glass opacities in both lungs.
Chest CT shows minimal interlobular septal thickenings and bilateral minimal pleural effusion, suggesting mild pulmonary edema.
On follow up chest PA shows rapidly improved GGOs and bilateral pleural effusion, suggesting pulmonary edema.
The peripheral blood smear showed typical ring form trophozoites.
- Brief Review
- Malaria is caused by four species of Plasmodia; P. falciparum, P. vivax, P. ovale, and P. malariae. Fever with chills, sweating, anemia, leucopenia, and splenomegaly are the mot common clinical findings. Typical clinical symptom are periodicity of the episodic fever (tertian or quartan), every 48 and 72 hours. Reported complication of malaria include pulmonary disease, CNS dysfunction, nephrotic syndome, coagulation abnormalities, bone marrow hyperplasia and spleenic rupture. Pulmonary complications with malaria range from simple respiratory symptoms to reported of pulmonary edema and ARDS. A few reports of acute pulmonary edema associated with quinine therapy have been reported.Severe P falciparum infections is the type most commonly associated with ARDS, but cases caused by P vivax and P ovale habe also been reported. Radiographic and CT findings are consistent with noncardiogenic pulmonary edema, pleural effusion, diffuse interstitial edema, and lobar consolidation may also be seen. Occasionally, bronchiolitis obliterans organizing pneumonia has been reported. The current hypothesis of pulmonary edema and ARDS in malaria are primary lung injury, changes result from vascular injury related to red blood cell sequestration and destruction, the release of parasite and erythrocyte material into the circulation, and the host response to these event.
