摘要
一名 81 岁的男子最近到伯利兹旅行后，因右大腿上出现红斑和触痛而到急诊就诊。护理点超声检查（POCUS）发现皮下组织有一个带有声影的高回声结构。对该结构进行彩色多普勒评估后发现有闪烁假象。切除该结构后，病理鉴定该物体为人肤蝇幼虫（Dermatobia hominis larva）。POCUS 的使用有助于识别和定位皮下异物。彩色多普勒的使用产生了闪烁假象，这在以前的报告中从未有过，因为在对蝇幼虫进行超声评估时发现了这一假象。
Twinkle Artifact Observed During POCUS of a Human Myiasis Caused by the Dermatobia hominisBotfly.
An 81-year-old man presented to urgent care for assessment of an area of erythema and tenderness on his right thigh after recent travel to Belize. Point of care ultrasound (POCUS) revealed a hyperechoic structure with acoustic shadowing in the subcutaneous tissue. Colour Doppler assessment of the structure produced a twinkle artifact. The structure was removed and pathology identified the object as a Dermatobia hominis larva (human botfly). The use of POCUS helped identify and localize the subcutaneous foreign body. The use of colour Doppler produced the twinkle artifact, which has not been previously reported as a finding produced during ultrasonographic assessment of botfly larvae.
