“…Whereas compression of the distal tibial nerve or its branches in the tarsal tunnel is well-recognized, entrapment or compression of the tibial nerve at the popliteal fossa is less frequently encountered in clinical practice [33,34]. Since entrapment of the tibial nerve by the tendinous arch of origin of the soleus muscle was first proposed, several etiologies, such as hematoma following trauma or surgery, nerve tumors, and Baker's cyst, have been demonstrated.…”

Role of magnetic resonance imaging in entrapment and compressive neuropathy—what, where, and how to see the peripheral nerves on the musculoskeletal magnetic resonance image: part 1. Overview and lower extremity

The diagnosis of nerve entrapment and compressive neuropathy has been traditionally based on the clinical and electrodiagnostic examinations. As a result of improvements in the magnetic resonance (MR) imaging modality, it plays not only a fundamental role in the detection of space-occupying lesions but also a compensatory role in clinically and electrodiagnostically inconclusive cases. Although ultrasound has undergone further development in the past decades and shows high resolution capabilities, it has inherent limitations due to its operator dependency. We review the general concepts that should be known to evaluate the entrapment and compressive neuropathy in MR imaging. We also review the course of normal peripheral nerves, as well as various clinical demonstrations and pathological features of compressed and entrapped nerves in the lower extremities on MR imaging, according to the nerves involved. The common sites of nerve entrapment of the lower extremity are as follows: sciatic nerve around the piriformis muscle; tibial nerve at the popliteal fossa and tarsal tunnel, common peroneal nerve around the fibular neck, and digital nerve near the metatarsal head. Although MR imaging can depict the peripheral nerves in the extremities effectively, radiologists should be familiar with nerve pathways, common sites of nerve compression, and common space-occupying lesions resulting in nerve compression in MR imaging.

“…13 The PTN has been reported to be compressed by isolated problems, such as a ruptured popliteus muscle, 14 orthopedic hardware, 15 or by a Baker's cyst. 16 There have been a few case reports in which the soleal sling was been identified as the source of PTN compression. 9,10,17 The clear description recently in a cadaver series has defined the soleal sling as a potential location for a nerve compression.…”

Combined compression of both the common peroneal nerve and the proximal tibial nerve at the level of the popliteal fossa is rare. Recently, an anatomic site of compression of the proximal tibial nerve at the soleal sling (originating arch for the soleus muscle) has been described in cadavers. The present report includes three patients who had a combined compression of the common peroneal nerve at the fibular neck (fibular tunnel syndrome) and compression of the proximal tibial nerve at the soleal sling (soleal sling syndrome). In each case, blunt trauma was the precipitating event. Neurolysis of both nerves resulted in restoration of motor and sensory function in each of these three patients. This is the first clinical report illustrating combined neurolysis of the common peroneal at the knee and the proximal tibial nerve in the soleal sling.

“…Differentiating between DVT and a dissecting cyst (extending into the calf) is critical to providing appropriate treatment and failure to do so may have catastrophic results. Additional reports implicate popliteal cysts in nerve entrapment syndromes, and as a source of increased risk of infection (Handy, 2001;Olcott & Mehigan, 1986;Sansone, Sosio, de Gama Malcher, & De Ponti, 2002). Popliteal masses may also be associated with PVNS, a disease of the synovium (Tatari et al, 2000), synovial sarcoma (Ayoub, Davies, Mangham, Grimer, & Twiston Davies, 2000), lipoma, or muscle herniation (Fritschy et al, 2006).…”

Recurrent Popliteal Cyst in an Adult

Popliteal cysts are typically secondary to an intra-articular pathology in adults but may occur as primary lesions unrelated to knee injury. Careful examination of any mass forming on the posterior aspect of the knee is needed to differentiate benign from malignant conditions. Asymptomatic cysts are often treated conservatively, whereas surgical intervention is recommended for troublesome cysts and for those related to intra-articular derangements. Surgical intervention focused on amelioration of intra-articular derangements and the communication between the knee and the popliteal cyst results in cyst recurrence of less than 5%. A report of a recurrent popliteal cyst, in spite of aggressive surgical intervention, is presented.
