Recognition of the normal magnetic resonance (MR) imaging appearances of the capsular ligaments of the knee is of great importance. These ligaments contribute to stability of the knee joint and are frequently injured. In this article, we describe the normal MR imaging anatomy of the capsular ligaments of the knee including the lateral and medial collateral ligamentous complexes, the extensor mechanism, and the supporting ligamentous structures of the proximal tibiofibular joint. Normal MR imaging findings and important anatomic variants of the neurovascular structures of the knee are also described.

Intraneural ganglion cysts are nonneoplastic, mucinous cysts within the epineurium of peripheral nerves which usually involve the peroneal nerve at the knee. A 37-year-old female presented with progressive left buttock and posterior thigh pain. Magnetic resonance imaging revealed a sciatic nerve mass at the sacral notch which was subsequently revealed to be an intraneural ganglion cyst. An intraneural ganglion cyst confined to the proximal sciatic nerve has only been reported once prior to 2009.

✓ Different theories have evolved to explain the pathogenesis and the cell of origin of intraneural ganglion cysts. Reportedly only three cases of intraneural ganglion of the tibial nerve have been located within the popliteal fossa, and all of these were thought to arise within the nerve. The authors report a case of a recurrent tibial intraneural ganglion in which a connection to the proximal tibiofibular joint was demonstrated on magnetic resonance (MR) images and at surgery. Surgical ligation of the articular branch and evacuation of the cyst led to symptomatic relief, and an MR image obtained 1 year after surgery documented no recurrence. This case reinforces the fact that surgeons need to consider and search for an articular connection in all cases of intraneural ganglia, especially in those that have recurred.

Background Intraneural ganglion cysts of the ulnar nerve at the wrist are rare and poorly understood. We report a case of an intraneural ganglion cyst at the level of the wrist. Case presentation: A 48-year-old man presented with the complaints of weakness for 6 months and serious aggravation for 1 month in his right hand. After examinations, including ultrasound, the patient was diagnosed with an intraneural ganglion cyst. Intraoperatively, with exposure of the ulnar nerve, we found that the intraneural ganglion cyst was at the level of Guyon’s canal and extended approximately 6 cm proximally. Postoperatively, sensation of the fingers was normal, but atrophy of his muscles and limited straightening of his ring and little fingers were similar to those preoperatively. Conclusions Diagnosis of an intraneural cyst before surgery is mostly based on ultrasound and magnetic resonance imaging. Transection of the articular branch is an important measure to prevent recurrence of this cyst. If the ulnar nerve is compressed and causes symptoms, nerve decompression, including removal/aspiration of the cyst, and sometimes external neurolysis of the nerve, are necessary to relieve the symptoms and allow regeneration of the nerve. However, these should be performed without damaging the nerve fascicles.

Objectives: Tendinopathy of the flexor hallusis longus tendon is common in the athletes. This case is intended to be reported diagnose and treatment ganglion cyst contiguity of the flexor hallucis longus tendon that located atypical region and adversely affect the athlete's training program. Methods: 25-year-old male national swimmer was assessed with a left ankle pain. He had an intensive training program in the pool using pallets at the everyday. Pain in the left ankle was localized posterior and distal of the medial malleolus . Ankle range of motion and muscle strength was full. Neurovascular examination was normal. Radiography with anterior posterior, lateral and oblique analysis was not any unusual finding. In the evaluation with magnetic resonance imaging, thickening of the tendon sheath and effusion around the flexor hallucis longus was revealed and tendon integrity was exact. Results: Conservative treatment was planned. It was applied non-steroidal anti-inflammatory medicine, modification of the training (without or low weight pallet), platelet rich plasma (two weeks, two times peer weeks). During the six-month follow-up the patient's symptoms improved, but with the increased intensity of training at follow-up complaints started again. Professional athletes who did not respond adequately to conservative treatment surgical exposure were planned. Patient is approached the flexor hallucis longus musculotendinous junction from the posteromedial ankle at the level of the posterior talar tubercles. During the tendon exposure cyst was found at the level of talocalcaneal joint. Excision of the cyst was achieved; its size was 5x5 mm, looking transparent, well defined and soft consistency. Tenolysis is accomplished from superior to inferior to the level of the superior calcaneus. A histopathologic examination result of the cyst consistent with ganglion cyst was detected. Sport-specific training program started at the 6 weeks. There was no recurrence during the 6 months follow-up. Conclusion: Tendon associated ganglion cyst is not usual although flexor hallucis longus tendinopathy is common in athletes. External pressure causes in addition to the overuse injuries should be remembered in the differential diagnosis of posterior ankle and medial arch pain. Clinical suspicion and magnetic resonance imaging are valuable in establishing the diagnosis. Tenolysis and excision of the associated mass has proven to be a relatively safe and successful procedure especially in highly demanded elite athletes.
