Tarsal tunnel syndrome: Four uncommon cases

Tarsal tunnel syndrome is rarely diagnosed. We describe four uncommon cases treated in our department: a case of angioleiomyoma of the tarsal tunnel never reported in the literature, a case of neurilemoma of the posterior tibial nerve, a big ganglion of the tibiotarsal joint and a pes planus with valgus talus in a young male affected by cerebral palsy. All the cases were treated by surgery with a good outcome. The article includes a discussion about aetiology, diagnosis and treatment of this syndrome.
