11/43. Intraspinal extradural ganglion cyst of the cervical spine.

    Intraspinal ganglion cyst is an uncommon lesion, which occurs most frequently in the lower lumbar region; occurrence in the cervical region is extremely rare. We report a case of ganglion cyst in the cervical region and describe its clinical pathological and radiological findings. A 59-year-old man presented with sudden lower limbs weakness and numbness below the nipple level. magnetic resonance imaging revealed an intraspinal extradural lobulated cystic lesion at the level of C6-7 in contact with the left facet joint and posterior erosion of the spinal process at C7. The spinal cord was severely compressed by this lesion which was hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging and short T1 inversion recovery. The cyst wall was strongly enhanced after contrast injection. Intraoperatively, the mass was found to arise from the capsule of the C6-7 facet joint. The excised cyst contained jelly-like fluid. The patient's neurologic symptoms had fully recovered 20 days after the operation. The histopathologic analysis was consistent with ganglion cyst. Ganglion cyst of the cervical region is extremely rare, but must be considered in the differential diagnosis of intraspinal extradural compressive syndromes.

12/43. tarsal tunnel syndrome caused by epineural ganglion of the posterior tibial nerve: report of 2 cases and review of the literature.

    ganglia within the posterior tibial nerve is a rare condition. The authors report 2 cases of epineural ganglion of the posterior tibial nerve, causing tarsal tunnel syndrome. Both cases presented with numbness on the plantar surface of the foot. magnetic resonance imaging showed the presence of the cyst within the tarsal tunnel. During surgery, these cysts were found within the epineurium of the posterior tibial nerve and were successfully removed without damage to nerve fibers. Both patients were free of symptoms after surgery. ganglion cysts in the peripheral nerve are either intrafascicular or epineural. Intrafascicular ganglia present beneath the epineurium and involve the nerve fibers, whereas epineural ganglia are located in the epineurium and do not involve the nerve fibers. A review of the literature discusses these concepts. The authors suggest that epineural ganglion should be clinically distinctive from an intrafascicular ganglion because of the differences in surgical treatment, postoperative nerve function, and the recurrence rate.

13/43. Large lateral meniscal ganglion cyst extending into the intercondylar fossa of the knee.

    We report the case of a 31-year-old, otherwise healthy man with a large intra-articular meniscal ganglion cyst (27.7 x 13.5 mm) originating from the dorsal horn of the lateral meniscus. Clinically, the patient presented with knee pain in a squatting position. magnetic resonance imaging revealed a large intra-articular cyst in the posterior compartment. At arthroscopic surgery, the ganglion cyst was found in the intercondylar space posteriorly to the posterior cruciate ligament. After removal of the ganglion cyst, a horizontal tear in the dorsal horn of the lateral meniscus was revealed and treated by partial meniscectomy. To our knowledge, a meniscal ganglion cyst originating from the lateral meniscus and extending into the joint is an extremely rare event, with only two previous reported cases. We review the current literature on the pathogenesis, distribution, and treatment of meniscal ganglion cysts.

14/43. Intra-articular ganglia arising from the posterior joint capsule of the knee.

    magnetic resonance imaging (MRI) is an effective method to evaluate cystic lesions of the knee. Intra-articular ganglia of the knee joint was considered to be rare before the advent of MRI. However, because an MRI is often used to diagnose knee pathology, the reported prevalence of intra-articular ganglia has increased. We describe two cases of an intra-articular ganglion arising from the posterior joint capsule. Both cysts appeared to be arising from the posterior cruciate ligament by both MRI as well as arthroscopy through a lateral infrapatellar portal. However, arthroscopy through a posteromedial portal revealed the cysts to originate from the posterior joint capsule. It suggests that some of the ganglion arising from the posterior cruciate ligament reported in the literature might actually be from the posterior joint capsule. To prevent recurrence of a ganglion cyst, when preoperative MRI shows the mass to be located posterior to the cruciate ligaments, we recommend that the relationship of the ganglion cyst to the posterior joint capsule be evaluated at arthroscopy through the posteromedial or posterolateral portal.

15/43. A ganglion cyst that developed from the infrapatellar fat pad of the knee.

    A ganglion cyst may be seen in all joints with varying frequency depending on location, but it is rare in the knee joint. A 30-year-old man presented with a mass in the anterolateral aspect of his left knee. magnetic resonance imaging revealed an intra-articular tumor arising from the infrapatellar fat pad of the knee. This multilobular tumor showed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. Complete open resection was performed after arthroscopic examination. Histologic examination of the specimen confirmed the diagnosis of ganglion cyst. At the 1-year follow-up examination, the patient's left knee was completely asymptomatic with full range of motion and no recurrence. Ganglion cyst should be considered in the differential diagnosis of intra-articular masses.

16/43. subcutaneous emphysema of the hand caused by the suction drain -- a case report.

    subcutaneous emphysema of the hand can be related to non-infectious causes and most commonly high-pressure injection injuries. Surgical emphysema of the hand is rare. We report a case of surgical emphysema of the dorsum of the hand following the excision of a dorsal wrist ganglion when the inserted suction drain did not work properly, accompanied by the inadvertent compression of the patient's body. Conservative management was adequate; oedema and emphysema subsided in several days.

17/43. Dorsal wrist syndrome repair.

    Dorsal wrist pain with or without a palpable dorsal wrist ganglion is a common complaint. Watson developed the concept of the dorsal wrist syndrome (DWS) which is an entity encompassing pre-dynamic rotary subluxation of the scaphoid and the overloaded wrist. We reviewed 20 cases of DWS treated surgically. There were nine males (11 wrists) and nine females (nine wrists). Post-operative follow-up ranged from five to 67 months (mean, 37 months). At operation, we observed SLL tears in eight wrists and dorsal ganglia in 12 cases. Following surgery, 12 cases reported being pain free, five had mild pain, two moderate pain and one case reported severe pain. Post-operative extension/flexion was 73/70 average. Post-operative grip strength was 28 kg average. We believe that excision of the posterior interosseous nerve and the dorsal capsule including the ganglion, if present, provides pain relief in DWS.

19/43. Ganglion of the groin in a child: an unusual cause of soft-tissue swelling of the groin.

    A case of groin ganglion with asymptomatic compression of the femoral vein is described. A 2-year-old girl was referred because of a symptomless groin mass. A mass was palpable in the right femoral triangle. Computed tomography and ultrasonography revealed a cystic lesion compressing the femoral vein ventrally. Prompt surgical removal of the cystic lesion was done without complications. Histopathological examination showed a benign structure similar to that of a ganglion.

20/43. Intra-articular cysts and ganglia of the knee: a report of nine patients.

    Completely intra-articular cysts and ganglia of the knee are rare. They have been found in various locations such as on the anterior or posterior cruciate ligaments, in the infrapatellar fat pad, on the posterior wall of the posteromedial compartment and (very rarely) in connection to the menisci. We analyzed nine patients with intra-articular cysts or ganglia found in a series of 2,400 consecutive arthroscopies. In four patients, the cyst or ganglion was found attached to the anterior part of the ACL, in two patients it was located between the ACL and the PCL, and in the remaining three cases it was found in connection with the meniscus. In three out of the nine patients there was either no or very minor additional pathology found in the knee besides the cyst or the ganglion. We believe that intra-articular cysts and ganglia of the knee can be symptomatic, and excellent or good results after cyst removal can be expected especially when there is little additional pathology.
