Osteoblastomas are rare, benign bone tumors mainly arising from the long bones and the posterior vertebral arches. Skull localizations account for approximately 15% of cases. A total amount of thirty cases involving the temporal bone are reported in the literature. Clinical presentation of temporal osteoblastomas often includes local pain and swelling, while 7 and 8 cranial nerve impairment is rare. We report the novel finding of increase intracranial pressure syndrome secondary to dominant transverse-sigmoid sinus junction compression caused by a small temporal bone osteoblastoma. Excision of the tumor with the restoration of venous flow in the sigmoid sinus was followed by a prompt clinical improvement. In the management of patients with a venous sinus compression, restoration of venous drainage should be a priority.
骨母细胞瘤是一种罕见的良性骨肿瘤，主要起源于长骨和椎弓后部。颅骨部位的病例约占15%。文献报道颞骨受累的病例共有30例。颞骨骨母细胞瘤的临床表现通常包括局部疼痛和肿胀，而第7和第8颅神经受损则较为罕见。我们报告了一例由颞骨小骨母细胞瘤压迫横窦-乙状窦交界优势侧继发颅内压增高综合征的新发现。切除肿瘤并恢复乙状窦血流后，临床症状迅速改善。在处理静脉窦受压的患者时，恢复静脉引流应作为首要任务。
