Chordomas are rare, slow-growing malignant neoplasms derived from remnants of the embryological notochord. Pediatric cases comprise only 5% of all chordomas, but more than half of the reported pediatric chordomas are intracranial. For patients of all ages, intracranial chordomas typically present with symptoms such as headaches and progressive neurological deficits occurring over several weeks to many years as they compress or invade local structures. There are only reports of these tumors presenting acutely with intracranial hemorrhage in adult patients.
A 10-year-old boy presented with acute onset of headache, emesis, and diplopia. Head computed tomography and magnetic resonance imaging of brain were suspicious for a hemorrhagic mass located in the left petroclival region, compressing the ventral pons. The mass was surgically resected and demonstrated acute intratumoral hemorrhage. Pathologic examination was consistent with chordoma.
There are few previous reports of petroclival chordomas causing acute intracranial hemorrhage. To the authors' knowledge, this is the first case of a petroclival chordoma presenting as acute intracranial hemorrhage in a pediatric patient. Although uncommon, it is important to consider chordoma when evaluating a patient of any age presenting with a hemorrhagic lesion of the clivus.
脊索瘤是一种罕见的、生长缓慢的恶性肿瘤,起源于胚胎脊索的残余组织。儿科病例仅占所有脊索瘤的5%,但报告的儿科脊索瘤中半数以上位于颅内。对于所有年龄段的患者,颅内脊索瘤通常表现为头痛和渐进性神经功能缺损等症状,这些症状在数周数年中逐渐出现,因为肿瘤压迫或侵犯局部结构。仅有成人患者中这些肿瘤急性伴发颅内出血的报告。
一名10岁男孩出现急性头痛、呕吐和复视。头部计算机断层扫描和脑部磁共振成像怀疑左侧岩斜区有一个出血性肿块,压迫脑桥腹侧。该肿块经手术切除,显示为肿瘤内急性出血。病理检查结果符合脊索瘤。
既往关于岩斜区脊索瘤导致急性颅内出血的报道较少。据作者所知,这是首例儿科患者中表现为急性颅内出血的岩斜区脊索瘤。尽管不常见,但在评估任何年龄出现斜坡出血性病变的患者时,考虑脊索瘤很重要。
