Calibre-persistent labial artery (CPLA) is a rare lip vascular lesion. High-resolution Colour Doppler Ultrasonography aids in its accurate diagnosis, preventing potential surgical complications.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Oral Medicine
Background:
- Calibre-persistent labial artery (CPLA) is an underdiagnosed arterial anomaly of the lip.
- Misdiagnosis can result in severe bleeding complications during surgical procedures.
Observation:
- A 24-year-old male presented with an asymptomatic, pulsating nodule on the upper lip.
- Initial diagnosis suggested a peripheral angiomatous lesion.
Findings:
- High-resolution Colour Doppler Ultrasonography confirmed the presence of a calibre-persistent labial artery.
- This non-invasive imaging modality proved effective in diagnosing the vascular lesion.
Implications:
- Accurate diagnosis of CPLA is crucial for clinicians to avoid surgical misadventure.
- This case highlights the importance of considering CPLA in the differential diagnosis of lip swellings.
- Colour Doppler Ultrasonography is recommended for definitive diagnosis of CPLA.
