Schwannomas are rare, benign tumors that develop from Schwann cells in the peripheral nervous system, and they make up only a small fraction of cases found in the upper limbs. Oftentimes, these tumors do not show symptoms until they start pressing on nearby structures. In this case report, we share the case of a 34-year-old woman who had painless swelling in her right distal forearm for three years. Unfortunately, this swelling eventually led to numbness and pain along the distribution of her median nerve. An MRI revealed a well-defined lesion associated with the median nerve, and a biopsy confirmed it as a schwannoma. After surgically removing the tumor, she experienced complete relief from her symptoms. This case underscores the importance of considering schwannomas when evaluating forearm masses and provides insight into the diagnostic and surgical approaches involved in managing these tumors.
神经鞘瘤是一种罕见的良性肿瘤，由周围神经系统的施万细胞发展而来，在上肢发现的病例中只占一小部分。通常情况下，这些肿瘤在开始压迫附近结构之前不会出现症状。在本病例报告中，我们分享了一名34岁女性的病例，她右前臂远端无痛肿胀三年。不幸的是，这种肿胀最终导致沿正中神经分布区域出现麻木和疼痛。磁共振成像显示一个与正中神经相关的边界清晰的病变，活检证实为神经鞘瘤。手术切除肿瘤后，她的症状完全缓解。该病例强调了在评估前臂肿块时考虑神经鞘瘤的重要性，并为处理这些肿瘤所涉及的诊断和手术方法提供了见解。
