Nonseptic lateral sinus thrombosis (NSLST) differs from septic lateral thrombosis (SLST) in that it is not associated with ear or sinus infection, it usually occurs in the adult population, and it has an ambiguous clinical presentation. The otolaryngologist is often consulted about diagnostic findings associated with lateral sinus thrombosis. We report three cases of NSLST that required otolaryngologic assessment. The patients were women, ages 23 to 31 years. Presenting symptoms were headaches in all three patients; one also had concomitant ear pain. Two patients had negative head computed tomography scans; only magnetic resonance imaging was diagnostic. Treatment of NSLST consists of anticoagulation and elimination of predisposing factors. Familiarity with this condition is fundamental for early diagnosis and initiation of appropriate therapy. We discuss the origins and causes of NSLST, clinical presentation, preferred diagnostic strategy, and treatment alternatives.
非化脓性外侧窦血栓形成（NSLST）与化脓性外侧窦血栓形成（SLST）不同，在于它与耳部或鼻窦感染无关，通常发生于成年人群，且临床表现不明确。耳鼻喉科医生常被咨询有关外侧窦血栓形成的诊断结果。我们报告3例需要耳鼻喉科评估的NSLST病例。患者均为女性，年龄23至31岁。所有3例患者的主要症状均为头痛；1例还伴有耳痛。2例患者头部计算机断层扫描结果为阴性；仅磁共振成像具有诊断价值。NSLST的治疗包括抗凝和消除诱发因素。熟悉这种疾病对于早期诊断和启动适当治疗至关重要。我们讨论了NSLST的起源、病因、临床表现、首选诊断策略和治疗选择。
