1/52. anterior cruciate ligament ganglion: case report.

    CONTEXT: A ganglion is a cystic formation close to joints or tendinous sheaths, frequently found in the wrist, foot or knee. Intra-articular ganglia of the knee are rare, and most of them are located in the anterior cruciate ligament. The clinical picture for these ganglia comprises pain and movement restrictions in the knee, causing significant impairment to the patient. Symptoms are non-specific, and anterior cruciate ligament ganglia are usually diagnosed through magnetic resonance imaging or arthroscopy. Not all ganglia diagnosed through magnetic resonance imaging need to undergo surgical treatment: only those that cause clinical signs and symptoms do. Surgical results are considered good or excellent in the vast majority of cases. CASE REPORT: A 29-year-old male presented with pain in the left knee during a marathon race. physical examination revealed limitation in the maximum range of knee extension and pain in the posterior aspect of the left knee. Radiographs of the left knee were normal, but magnetic resonance imaging revealed a multi-lobed cystic structure adjacent to the anterior cruciate ligament, which resembled a ganglion cyst. The mass was removed through arthroscopy, and pathological examination revealed a synovial cyst. Patient recovery was excellent, and he resumed his usual training routine five months later. ( info)

2/52. Unusual solid ganglia of the anterior cruciate ligament mimicking lateral meniscal tears.

    Previous investigators have reported incidental findings and symptomatic cases of cystic ganglia on the anterior cruciate ligament (ACL) that were mucinous degeneration or herniation of the synovial tissue through a defect. However, we report 2 cases of grossly solid ganglia of the ACL those mimicked lateral meniscal tears. A literature search found no previous report of them. We discuss the possibility of their pathogenesis and treatment. ( info)

3/52. Unusual solitary ganglion cysts of the anterior segment of the lateral meniscus.

    Generally, ganglion or synovial cysts have been reported to originate from numerous structures in and around the knee joint, including the anterior cruciate ligament, posterior cruciate ligament, popliteal tendon, and menisci. Nevertheless, a ganglion is not a synovial cyst and there is no synovial lining. Meniscal cysts present a subgroup of ganglion cysts that occur in association with meniscal tears. We report 2 cases of unusual meniscal cyst from the anterior segment of the lateral meniscus without any meniscal tear and discuss the possibility of their pathogenesis and treatment. ( info)

4/52. Compression of the ulnar nerve at the elbow by an intraneural ganglion.

    A rare cause of ulnar nerve compression at the elbow is presented in this report. A 42 year old right-handed mechanic developed subacute, progressive numbness, tingling and weakness in his right hand. Electrophysiologic studies demonstrated a severe conduction block affecting the ulnar nerve in the retrotrochlear groove but without any sign of major axonal loss. His hand functions were carefully studied prior to surgery. While fine motor tasks were not affected, the hand strength was markedly diminished. At surgery, a 1-cm diameter intraneural ganglion at the site of the conduction block was found and excised. The patient made a dramatic recovery within 6 weeks post-surgery. The conduction block completely resolved and the hand functions also returned to normal. This and other reported cases point to the importance of early diagnosis and intervention. ( info)

5/52. Giant ganglion cyst of the quadriceps femoris tendon.

    We present the case of a ganglion cyst with 11 x 3 x 2 cm dimensions originating from the quadriceps femoris tendon. The patient presented with palpable mass and chronic pain in the anterolateral thigh region. The pain increased with walking. ultrasonography and computed tomography revealed a cystic, well defined lesion in the vastus lateralis muscle. The patient was operated on and the cyst excised; it was seen to be a ganglion cyst. The patient is asymptomatic 6 months after surgery. This is a very rare localization for a giant synovial cyst, and preoperative diagnosis is a challenge for the surgeon. ( info)

6/52. An intraligamentous ganglion cyst of the anterior cruciate ligament after a traumatic event.

    An unusual case of intraligamentous ganglion cyst of the anterior cruciate ligament after a traumatic event in a 12-year-old boy is presented. magnetic resonance imaging was helpful in delineating the lesion. An arthroscopic aspiration of the cyst material resulted in resolution of symptoms to preserve satisfactory knee function. The patient remains asymptomatic 25 months after surgery. ( info)

7/52. Arthroscopic treatment of a ganglion of the first metatarsophalangeal joint.

    The case of a ganglion that had developed around the first metatarsophalangeal (MTP) joint and in which several other therapeutic approaches were unsuccessful was treated using an arthroscopic assisted procedure. During MTP arthroscopy, we found that the pedicle of the tumor was attached to the interior of the joint, and the lesion was successfully extirpated. communication with the cyst was found on the medial side of the lateral sesamoid bone, which coincided with the rounded portion of the first MTP joint at the sole, where stress is exerted repeatedly while walking. Thus, the intracystic fluid could not return to the intra-articular space. Instead the cyst gradually extended to the extra-articular tissue, where it was relatively loosely connected. Researchers suspect that a ganglion originally develops through repeated mechanical stress; the lesion is constantly under pressure because of the weight bearing on it. Because of a higher pressure within the MTP joint, the communicating opening acts as a valve. ( info)

8/52. Intra-articular ganglion cyst of the knee.

    ganglion cysts of the knee are extremely uncommon. They usually cause non-specific symptoms and do not produce classical signs. Advances in imaging techniques as well as widespread use of arthroscopy have made detection of these cysts easier, and most can be treated arthroscopically. ganglion cysts arising within the infrapatellar fat pad are even more uncommon. We report a case of a young lady with a giant intra-articular ganglion within the infrapatellar fat pad that was treated by open excision. ( info)

9/52. wrist joint ganglion presenting as a painless mass in the palm: report of 2 cases.

    Ganglions occur commonly in the wrist and arise from the radiocarpal and intercarpal joints. Although ganglions present commonly as masses on the dorsal or volar surface of the wrist, ganglions from wrist joints appear rarely at other locations in the hand. We report 2 cases of ganglions arising from wrist joints that presented as painless masses in the center of the palm without signs or symptoms of median or ulnar nerve compression. Surgical treatment required extensile exposure to trace the proximal stalks to their joints of origin. knowledge of the possibility that a painless mass in the palm could be a ganglion arising from a joint in the wrist allows proper presurgical planning and informed consent.

10/52. leiomyoma of the hand mimicking a pearl ganglion.

    Leiomyomas rarely occur in the hand. To our knowledge, there have been no reports of a leiomyoma of the hand mimicking a pearl ganglion in the English literature. We report such a case with a leiomyoma of the right third finger in a 59-year-old woman. The tumor was excised together with the underlying sheet of tissue. The pathology revealed that the tumor was linked to the underlying structure of a vascular wall by a stalk of tumor tissue. This report serves to remind clinicians to include leiomyoma in the differential diagnosis when encountering a 'ganglion-like lesion'. Also, this report demonstrates the link between a leiomyoma and its underlying origin. ( info)
