Abstract

Os autores relatam o caso de uma paciente de 24 anos de idade, que apresentou dor e aumento do volume do hálux esquerdo há três meses. A ultra-sonografia mostrou massa sólida, hipoecóide, heterogênea, com áreas císticas e calcificação, no dorso do hálux esquerdo, em partes moles, com estrutura tendínea no seu interior, sem aparente comprometimento de estruturas ósseas. O estudo com Doppler colorido mostrou hipervascularização central e periférica na lesão. A ressonância magnética evidenciou massa sólida, de partes moles, com estrutura tendínea no seu interior, com médio sinal em T1 e alto sinal em T2, com realce intenso e heterogêneo pelo meio de contraste paramagnético, sem acometimento de estruturas ósseas. A paciente foi submetida a procedimento cirúrgico, com ressecção da lesão descrita, no dorso do hálux esquerdo, e o exame anatomopatológico demonstrou tratar-se de sarcoma sinovial fibroso monofásico.The authors report a case of a 24 year-old female patient with a three-month history of pain and enlargement of the left halux. Ultrasound showed a heterogeneous, hypoechoic solid soft tissue mass with cystic areas and calcification in the dorsum of the left halux. A tendinous structure was identified within the lesion but no evidence of involvement of adjacent osseous structures was found. Doppler ultrasound revealed central and peripheral hypervascularization of the lesion. Magnetic resonance imaging demonstrated a solid soft tissue mass containing a tendinous structure. The lesion appeared as an intermediate signal intensity structure on T1 images, high signal intensity on T2 images, and showed marked enhancement after intravenous administration of gadolinium. No osseous lesions were identified. The patient was submitted to surgical resection of the lesion in the dorsum of the left halux and the pathology results revealed a monophasic fibrous synovial sarcoma.
