Poland's syndrome is a rare non-inherited congenital anomaly. The authors describe the classic radiologic findings of Poland's syndrome by reporting the case of a male four-year old patient with asymmetry of hands and chest, illustrating the fundamental imaging criteria for a conclusive diagnosis.
Keywords: Poland's syndrome; Chest asymmetry; Congenital malformation.
A síndrome de Poland é uma anomalia congênita rara não hereditária. Os autores descrevem os achados radiológicos clássicos da síndrome de Poland através de um relato de caso de um paciente masculino de quatro anos de idade com assimetria torácica e das mãos, ilustrando os critérios imaginológicos fundamentais para a conclusão diagnóstica.
Unitermos: Síndrome de Poland; Assimetria torácica; Malformação congênita.
Poland's syndrome is characterized by pectoralis muscle agenesis associated with ipsilateral brachydactyly(14) . Although more rarely, other alterations may be associated with the syndrome whose early diagnosis may contribute for the therapeutic management of the condition.
A male, four-year-old patient with a history of no particular finding at prenatal follow-up and term birth with Apgar 9/10 was referred for study with chest computed tomography for deformity of the left anterior chest wall associated with asymmetry between his hands (smaller at left) detected at puericulture consultation. The patient did not present any motor, sensorial or neurological deficits.
Clinical examination detected axillary folds asymmetry, left nipple depression, volumetric reduction of the pectoral region and of the left hand as compared with the right side (Figure 1).
Non-contrast-enhanced helical computed tomography was performed with the objective of evaluating the soft tissues and bone structures, demonstrating pectoralis major and minor muscles at the left (Figure 2). Vertebral bodies, costal arches, mediastinum and pulmonary parenchyma were found within normality parameters. A supplementary ultrasonography study (Figure 3) was performed, demonstrating the same findings. Doppler ultrasonography of the subclavian and axillary vessels demonstrated symmetrical vascular structures, with normal caliper as well as normal arterial and venous blood flow. Radiography of the hands for comparative analysis confirmed subtle hypoplasia of the left hand bones, with no sign of syndactyly or other local skeletal deformity (Figure 4).
Poland's syndrome is a rare congenital disorder fundamentally characterized by unilateral agenesis of the pectoral muscles associated with ipsilateral brachydactyly(14) . Individuals affected by this syndrome may also present several other alterations, such as hypoplasia or agenesis of the nipple and breast parenchyma, hypoplasia or aplasia of the costal arches, shortening of upper limb due to hypoplasia of the radius and ulna, syndactyly, among other less frequently described abnormalities, such as dextrocardia, single transverse palmar crease, scapular anomalies, vertebral anomalies, and anomalies of the urinary and digestive systems(3,59) .
With a still unknown etiology, Poland's syndrome affects a higher percentage of boys than girls, with the right side of the body being most frequently affected. In spite of the eminently clinical diagnosis, the radiological evaluation is justifiable for staging of the alterations found in addition to the classical findings, thus directing the treatment. The early diagnosis may contribute to pediatric, orthopedic, psychomotor and aesthetic management (the latter, with greater impact on women with amastia), as well as to the awareness of parents and family members, and to the social and school life of the child(1,2,4,6) .
