Schwannoma, also known as neurilemoma, is the most common tumour of peripheral nerves. Although it is the most common tumour of peripheral nerves, it is seldom seen in adult population. We present a very rare case of schwannoma in an unusual localization. The presented case concerns a 58-year-old patient with a slowly growing popliteal mass and neuralgia for 6 months. A mass originating from a nerve or compressing a nerve was thought in the differential diagnosis. Ultrasonographic and magnetic resonance imaging revealed a heterogenous, well-defined solid mass that seems to originate from tibial nerve. Surgical excision and histopathological examination confirmed the diagnosis of schwannoma. Diagnosis of the neurilemmoma originating from lower extremity peripheral nerves may be delayed because the mass can be misdiagnosed as baker cyst or the symptoms of the patient can be thought as a result of lumber disc herniation.
施万细胞瘤，也称为神经鞘瘤，是周围神经最常见的肿瘤。尽管它是周围神经最常见的肿瘤，但在成人中很少见。我们报告了一例非常罕见的位于不寻常部位的施万细胞瘤病例。该病例为一名58岁患者，腘窝处有一缓慢生长的肿块，并伴有6个月的神经痛。鉴别诊断时考虑为起源于神经或压迫神经的肿块。超声和磁共振成像显示一个边界清晰的异质性实性肿块，似乎起源于胫神经。手术切除及组织病理学检查确诊为施万细胞瘤。起源于下肢周围神经的神经鞘瘤的诊断可能会延迟，因为肿块可能被误诊为腘窝囊肿，或者患者的症状可能被认为是腰椎间盘突出症的结果。
