Osteoid osteomas are benign, solitary bone-forming tumors associated with progressively worsening pain. The exact etiology remains unclear, although it is speculated to result from neoplasia, direct trauma, or an inflammatory process. We present a rare case of a 53-year-old male who presented to the ED with a one-year history of worsening right ear pain and no significant medical or surgical history. On physical examination, the right mastoid area was tense and swollen, without signs of inflammation. Following an enhanced and non-enhanced CT, a diagnosis of an osteoid osteoma was established. This case report contributes imaging data regarding this unusual location for an osteoid osteoma.
骨样骨瘤是一种良性的、孤立的成骨性肿瘤，伴有逐渐加重的疼痛。尽管推测其病因是肿瘤形成、直接创伤或炎症过程，但确切病因仍不清楚。我们报告一例罕见病例，一名53岁男性因右耳疼痛加重一年就诊于急诊科，既往无重大内科或外科病史。体格检查发现，右侧乳突区紧张肿胀，无炎症迹象。经增强和非增强CT检查后，确诊为骨样骨瘤。本病例报告提供了关于骨样骨瘤这一不寻常部位的影像学资料。
