RESUMO
INTRODUCTION: An intra-neural ganglion cyst of the lateral dorsal cutaneous branch of the sural nerve is rare, with only a few cases reported in the literature. MATERIALS AND METHODS: We carried out a retrospective investigation of patients with an intraneural ganglion cyst of the lateral dorsal cutaneous nerve. RESULTS: We present a case series of four patients with intra-neural ganglion cysts of the lateral dorsal cutaneous nerve, the distal continuation of the sural nerve at the lateral aspect of the foot. CONCLUSION: Intra-neural ganglion cysts of the lateral dorsal cutaneous nerve are rare. They represent a relatively uncommon source of lateral ankle pain, which can easily be diagnosed with ultrasound (US) and magnetic resonance imaging and managed effectively with US-guided aspiration or surgical excision.

Carpal tunnel syndrome (CTS) represents the most common entrapment neuropathy of the upper extremity. Intermittent CTS has been reported in the surgical literature and usually, related to masses associated to flexor tendons. We describe a patient with an intrasynovial lipoma involving the deep flexor of the middle finger causing intermittent CTS and snapping on flexion-extension.
