Juvenile nasopharyngeal angiofibroma (JNA) is the most common benign neoplasm of the nasopharynx. Almost always unilateral on diagnosis, JNAs are locally invasive and may extend across the midline, giving a false bilateral appearance; as such, true bilateral JNA is exceedingly rare. We present a recent case of true bilateral JNA.
Single case report of a patient with bilateral JNA, including clinical presentation, diagnosis, and management.
The patient presented with unilateral nasal obstruction and recurrent epistaxis. Computed tomography and magnetic resonance imaging demonstrated bilateral, noncontiguous masses. Angiography revealed independent vascular supplies from each respective side with no bilateral supply noted. The patient underwent preoperative embolization followed by endoscopic surgical removal of the larger mass; no complications were noted. Follow-up at 2 years demonstrated no recurrence or growth.
The vast majority of JNAs are unilateral, though invasive growth to the contralateral side may appear "bilateral" in presentation. Proper identification of true bilateral JNA is helpful in guiding management, wherein excision of both tumors may not be necessary.
青少年鼻咽血管纤维瘤(JNA)是鼻咽部最常见的良性肿瘤。几乎所有JNA在诊断时均为单侧,但具有局部侵袭性,可能会越过中线,造成双侧假象;因此,真正的双侧JNA极为罕见。我们报告一例近期的真正双侧JNA病例。
对一名双侧JNA患者进行单病例报告,包括临床表现、诊断和治疗。
该患者表现为单侧鼻塞和反复鼻出血。计算机断层扫描和磁共振成像显示双侧不连续肿块。血管造影显示两侧各自独立的血供,未发现双侧供血。患者接受了术前栓塞,随后通过内镜手术切除较大的肿块;未发现并发症。2年随访显示无复发或生长。
绝大多数JNA为单侧,尽管向对侧的侵袭性生长在表现上可能看似“双侧”。正确识别真正的双侧JNA有助于指导治疗,其中可能无需切除双侧肿瘤。
