Core Tip

Core tip: This is a retrospective study to emphasize the characteristic magnetic resonance imaging (MRI) features of the intraneural ganglion cyst (INGC) of the peripheral nerves. The radiologist should recognize the classic MRI pattern of the INGC, its joint connection and imaging anatomy of the involved nerve. This would aid surgeons in complete removal of the cyst, prevent its recurrence and hence improved patient outcomes. Both radiologists and surgeons should be aware of other neurogenic lesions and the extra neural ganglion cyst which may also have a joint connection.
