A particular case of breast asymmetry in a teenage girl

Abstract

Aim: The present article intends to underline the importance of breast ultrasonography in investigating a frequent problem that concerns mostly teenagers – breast asymmetry. Method: We present a case of breast asymmetry in a 17 years old girl. The clinical exam revealed that the left breast was enlarged approximately 4 times compared to the right breast (about 1.2Kg versus 0.300Kg). The left breast had a normal appearance and a homogenous consistency. We performed an ultrasound exam using Voluson Expert. Results: Ultrasonography demonstrated the presence of a significant large tumour, 15/8cm in diameter, which pushed the rest of the normal breast tissue towards the median line. The sonographyc characteristics of the mass were: hypoechogenicity, nonhomogenous echo pattern with linear internal echoes, sharp margins, no change in the posterior echogenicity and width to height ratio >1. The patient underwent surgery and the tumour was completely removed. The hystopathologic diagnosis was Phyllodes Tumour. Conclusion: Although constitutional breast asymmetry may be a frequent finding (with 10% prevalence), secondary causes (such as tumours) must be considered before recommending reconstructive surgery. Breast ultrasound can provide significant information in the diagnosis of breast asymmetry, providing accurate results that will help choose the appropriate surgical treatment.
