We present the case of a 19-year-old patient who was admitted with a subcutaneous scalp lump associated with bilateral papilloedema. CT demonstrated a large heterogeneous vault lesion destroying the right parietal bone. The mass was hyperdense and enhanced slightly with contrast. An important intracranial epidural extension was also demonstrated. The mass was completely removed through a parietal craniectomy and histological examination was characteristic for a B-cell non-Hodgkin's lymphoma. Staging revealed other bony lesions and neoplastic cells were also found in the CSF. Systemic and intrathecal chemotherapy were administered. This report discusses both the clinical differential diagnosis of scalp masses and the radiological diagnosis of skull lesions.
我们报告一例19岁患者，因头皮下肿物伴双侧视乳头水肿入院。CT显示一个巨大的、不均匀的颅顶病变，破坏了右侧顶骨。肿块密度较高，增强扫描有轻微强化。还显示有重要的颅内硬膜外扩展。通过顶骨颅骨切除术将肿块完全切除，组织学检查显示为B细胞非霍奇金淋巴瘤。分期检查发现其他骨病变，脑脊液中也发现了肿瘤细胞。给予了全身和鞘内化疗。本报告讨论了头皮肿物的临床鉴别诊断以及颅骨病变的放射学诊断。
