Summary
Pulmonary arteriovenous malformations can cause recurrent hemoptysis and may be initially misdiagnosed. Early consideration of this condition is crucial for accurate diagnosis and effective treatment.
Area of Science:
- Cardiology
- Pulmonology
- Radiology
Background:
- Pulmonary arteriovenous malformations (PAVMs) are rare vascular anomalies.
- Hemoptysis is an uncommon but serious complication of PAVMs.
Observation:
- An elderly male presented with recurrent hemoptysis, initially treated as bacterial pneumonia.
- Imaging revealed a pulmonary arteriovenous malformation obscured by lung consolidation.
- The PAVM was diagnosed after a prolonged period of recurrent symptoms.
Findings:
- Coil embolization successfully treated the PAVM and resolved hemoptysis.
- Computed tomography confirmed resolution of lung shadowing post-embolization.
Implications:
- PAVMs should be included in the differential diagnosis for patients with unexplained or recurrent hemoptysis.
- Timely diagnosis and intervention can prevent severe complications associated with PAVMs.

283
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

435
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
