Need for an Urgent Ultrasound Examination for Neck Lump

Thromboembolic phenomenon is rare but serious consequence of ovarian hyperstimulation syndrome (OHSS) and in vitro fertilization (IVF) treatment. We present a case of thrombosis of the right internal jugular vein presenting as a neck lump to the ENT department. Ultrasonography of the neck and upper extremity revealed thrombosis of right internal jugular vein. The patient was started on low molecular weight heparin, which resulted in resolution of her clinical condition. Interestingly, the majority of cases after OHSS involve thrombosis of the upper extremities. ENT surgeons, general physicians, and infertility experts should consider this in the differential diagnosis of neck swellings, particularly after OHSS and IVF treatment, and in this case report, we emphasis the need for an urgent ultrasound of the neck in such patients.

血栓栓塞现象是卵巢过度刺激综合征（OHSS）和体外受精（IVF）治疗罕见但严重的后果。我们介绍一例右颈内静脉血栓形成的病例，患者因颈部肿块就诊于耳鼻喉科。颈部及上肢超声检查显示右颈内静脉血栓形成。患者开始使用低分子量肝素治疗，临床症状得到缓解。有趣的是，OHSS后的大多数病例涉及上肢血栓形成。耳鼻喉科医生、全科医生和不孕不育专家在对颈部肿胀进行鉴别诊断时应考虑到这一点，特别是在OHSS和IVF治疗后，在本病例报告中，我们强调对此类患者需紧急进行颈部超声检查。
