Abstract: Schwannomas are benign slow-growing tumors arising from the embryonic neural crest cells of the nerve sheaths of peripheral and cranial nerves, and they are a rare type of soft tissue mass that is usually always solitary. Generally, it grows in the head, neck, and flexor portions of the limbs, where many nerves are located. Schwannomas of the lung are extremely rare. Fewer than ten cases of schwannomas in this organ region have been reported in the existing literature. In this case report, a 40-year-old male non-smoker was hospitalized with occasional chest pain. His chest computed tomographic scan revealed a 3.8 cm space occupying lesion in the upper lobe of the right lung. This lesion has clear boundaries and uneven internal density. And it was concluded as a benign lesion possibility, it is preferred to be considered as a haematoma. This space occupying lesion was eventually confirmed as a schwannoma by needle biopsy tissues. Due to the presence in rare locations, such as the lung, the clinical presentation of this space occupying lesion is non-specific, making diagnosis difficult. The data presented in this case report can help clinicians to obtain information on the identification of this disease, which highlighted lung schwannoma as a differential diagnosis for patients with intermittent pain. It can also alert clinicians and radiologists to observe every detail of the radiology imaging findings.

具有挑战性的诊断：揭开肺神经鞘瘤影像学结果的谜团

摘要：神经鞘瘤是一种生长缓慢的良性肿瘤，起源于周围神经和颅神经神经鞘的胚胎神经嵴细胞，是一种罕见的软组织肿块，通常是孤立的。一般来说，它生长在头部、颈部和四肢的屈肌部分，这些地方有许多神经。肺部神经鞘瘤极为罕见。现有文献报道该器官区域神经鞘瘤的病例不到十例。在本病例报告中，一名 40 岁男性非吸烟者因偶尔出现胸痛而入院。他的胸部计算机断层扫描显示右肺上叶有一个 3.8 厘米的占位性病变。该病灶边界清楚，内部密度不均匀。且结论为良性病变可能性，优先考虑为血肿。该占位性病变最终通过穿刺活检组织证实为神经鞘瘤。由于存在于肺部等罕见部位，这种占位性病变的临床表现不具有特异性，导致诊断困难。本病例报告中提供的数据可以帮助临床医生获得有关该疾病的识别信息，这强调了肺神经鞘瘤作为间歇性疼痛患者的鉴别诊断。它还可以提醒临床医生和放射科医生观察放射成像结果的每个细节。
