Hampton's Hump-A Rare Radiological Feature in Patients with Pulmonary Embolism in a Single-Center Study

Area of Science:

• Radiology
• Pulmonology
• Cardiology

Background:

• Pulmonary embolism (PE) is a critical condition often presenting with non-specific symptoms.
• Computed tomography pulmonary angiography (CTPA) is vital for diagnosing PE.
• Hampton's hump, a rare sign of pulmonary infarction, is associated with PE.

Purpose of the Study:

• To investigate the association between Hampton's hump and pulmonary embolism severity.
• To explore the clinical significance of Hampton's hump in PE diagnosis.

Main Methods:

• Retrospective analysis of 428 patients undergoing CTPA.
• Correlation of Hampton's hump presence with PE severity markers and clinical outcomes.

Main Results:

• Hampton's hump correlated with rider-type embolism, pulmonary trunk/left pulmonary artery dilation, and pleural effusion.
• Patients with severe PE risk factors were more likely to exhibit Hampton's hump.
• Hampton's hump plus pleural effusion significantly increased in-hospital mortality risk.

Conclusions:

• Hampton's hump is a clinically significant, albeit rare, radiological marker in pulmonary embolism.
• The presence of Hampton's hump offers valuable prognostic information for PE patients.
