Primary malignant peripheral nerve sheath tumour (MPNST) is an uncommon malignant tumour that arises from the peripheral nerves. Most of these tumours arise in the regions of the trunk, head and neck, or extremities and are rarely seen in the abdomen. In this report, we describe a case of MPNST of the greater omentum, which, to the best of our knowledge, is only the second case reported in the literature. MPNST is an uncommon tumour that can show local invasion and has a high risk of recurrence. We also discuss the utility of "omental vascular pedicle sign" to help establish the omental origin of intra-abdominal masses.
原发性恶性外周神经鞘瘤（MPNST）是一种罕见的起源于外周神经的恶性肿瘤。这些肿瘤大多发生于躯干、头颈部或四肢，很少见于腹部。在本报告中，我们描述了一例大网膜MPNST，据我们所知，这是文献中报道的第二例。MPNST是一种罕见的肿瘤，可表现为局部浸润且复发风险高。我们还讨论了“网膜血管蒂征”在帮助确定腹腔内肿块网膜起源方面的作用。
