■未分化肉瘤被认为是一种罕见且侵袭性的软组织肉瘤,据报道下肢是软组织肉瘤的常见部位。
■我们在一名49岁女性中,在下肢多普勒超声检查中发现了罕见的未分化肉瘤,并表现为右侧血栓性小腿疼痛。
■关于超声波,呈现的未分化肉瘤表现为一个大的异质性,椭圆形,软组织肿块深深坐于右小腿,受累于比目鱼肌。超声的特征模仿了血肿的特征;然而,通过彩色多普勒应用显示内部血管,迅速排除了病变为血肿的可能性。然后将该病例转交给肉瘤分诊多学科小组进行审查。磁共振成像,计算机断层扫描和活检是这种情况的诊断检查的一部分,组织学证实软组织病变为未分化肉瘤。急诊右腿膝盖以上截肢术作为患者治疗的一部分。
■本病例报告提供了一种罕见的偶然发现,在下肢多普勒超声检查中发现未分化肉瘤,引起血栓性小腿疼痛。鼓励超声检查者在下肢多普勒超声压缩期间进行必要的注意并仔细检查任何相邻和偶然的软组织病变,二维成像和彩色成像,尤其是那些表现为恶性肿瘤的特征性病例;应将此类病例紧急转诊至三级软组织肉瘤中心进行进一步评估和治疗。
UNASSIGNED: Undifferentiated sarcoma is considered a rare and aggressive type of soft tissue sarcoma with the lower extremity reported as the common site for soft tissue sarcomas.
UNASSIGNED: We present a rare incidental finding of undifferentiated sarcoma during lower limb Doppler ultrasound with a presenting symptom of right thrombotic-like calf pain in a 49-year-old female.
UNASSIGNED: On ultrasound, the presented undifferentiated sarcoma appeared as a large heterogeneous, oval-shaped, soft tissue mass deeply seated in the right calf with involvement of the soleus muscle. The features on ultrasound mimicked those of a hematoma; however, the possibility of the lesion being a haematoma was promptly ruled out with the demonstration of internal vascularity on colour Doppler application. The
case was then referred to a sarcoma triage multidisciplinary team for a review. Magnetic resonance imaging, computed tomography and biopsy were parts of the diagnostic workup for this
case, histology confirmed the soft tissue lesion to be an undifferentiated sarcoma. Emergency above knee amputation of the right leg was performed as part of the patient\'s treatment.
UNASSIGNED: This
case report presents a rare incidental finding of undifferentiated sarcoma encountered during lower limb Doppler ultrasound causing thrombotic-like calf pain. Sonographers are encouraged to pay necessary attention and carefully examine any adjacent and incidental soft tissue lesion during lower limb Doppler ultrasound using compression, two-dimensional imaging and colour imaging, especially those that appear with characteristic features of malignancy; urgent referral should be made of such cases to a tertiary soft tissue sarcoma centre for further evaluation and management.
