Ganglion cysts are commonly observed in association with the joints and tendons of the appendicular skeleton. Ultrasonography is the favored modality used to manage such benign tumors, but it may suffer from operator subjectivity. In the treatment phase, ultrasonography also provides guidance for aspiration and injection, and the information regarding the accurate location of the pedicle of the ganglion. Thus, in this paper, we propose an automatic ganglion cyst extracting method based on fuzzy stretching and fuzzy C-means quantization. The proposed method, with its carefully designed image-enhancement policy, successfully detects ganglion cysts in 86 out of 90 cases (95.6%) without requiring human intervention.

Ganglion Cysts

Ganglion cysts are common soft tissue masses of the hand and wrist, and small size cysts are often hypoechoic. Thus, identifying them from ultrasonography is not an easy problem. In this paper, we propose an automatic segmentation method using two artificial intelligence algorithms in sequence. A density based unsupervised learning algorithm called DBSCAN is performed as a front-end and its result determines the number of clusters used in the Fuzzy C-Means (FCM) clustering algorithm for quantification of ganglion cyst object. In an experiment using 120 images, the proposed method shows a higher extraction rate (89.2%) and lower false positive rate compared with FCM when the ground truth is set as the human expert’s decision. Such human-like behavior is more apparent when the size of the ganglion cyst is small that the quality of ultrasonography is often not very high. With this fully automatic segmentation method, the operator subjectivity that is highly dependent on the experience of the ultrasound examiner can be mitigated with high reliability.

Background: The recurrence rate after open excision of ganglion cysts is approximately 20%. However, this literature is based on a small series of subjects. This study aims to determine the rate and risk of recurrence after open excision of ganglion cysts in a large patient series. Methods: This study included 628 patients who had ganglion cyst excision from 2010 to 2018. A retrospective chart review recorded the following: age, sex, laterality, volar/dorsal location, and recurrence. An overall recurrence rate was calculated. In addition, a 1-way analysis of variance test was used to compare recurrence rates among the individual surgeons, and unpaired t tests were used to compare age of recurrence, dorsal cyst recurrence, laterality of cyst, and recurrence based on sex. Finally, a comparison of recurrence rate over time was conducted for surgeon 3. Results: The overall recurrence rate was 3.8% (24 of 628). The recurrence rates for each surgeon were 3% (9 of 353), 2% (3 of 167), and 11% (12 of 107), P = .02. The age of those with and without a recurrence did not differ (32 years vs 38 years), P = .06. The recurrence rate of dorsal ganglion cysts was 4.1% (14 of 341) compared with 3.5% (10 of 286) for volar ganglion cysts, P = .69. Male patients had a recurrence in 6.4% (13 of 204) of cases compared with 2.6% (11 of 424) of female patients, P = 0.01. There was a decrease in the rate of recurrence from 42.9% to 5.3% over 5 years for surgeon 3. Conclusion: In our sample, male sex and surgeon experience were significant risk factors in ganglion cyst recurrence.

Background: Juxtafacet cysts, synovial and ganglion cysts, emanate from the facet joints. Patients with these cysts are typically asymptomatic but may rarely present with radiculopathy and/or myelopathy. Case Description: A 72-year-old female presented with a 1-month history of progressive lower extremity weakness (left more than right), numbness, and urinary incontinence. Notably, she also had a C7 sensory level to pin appreciation of 1-month duration. The magnetic resonance imaging showed an extradural C7 cystic lesion whose capsule enhanced with gadolinium, causing severe cord compression. The patient underwent a left C7 hemilaminectomy for complete excision of the cyst; postoperatively in 2-weeks duration, she regained full neurological function. The final histopathology was consistent with a ganglion cyst. Conclusion: Cervical juxtafacet cysts rarely cause compressive myelopathy. They may be readily diagnosed and resected with excellent postoperative outcomes.

Dorsal Ganglion

Background The etiology of dorsal wrist pain associated with loading of the wrist in extension has not been clearly identified in the literature. Purpose Many exercise disciplines incorporate upper extremity weight-bearing exercises in an extended wrist posture, for example push-ups, plank position, and various yoga and Pilates poses. This study evaluates patients with dorsal wrist pain in the extended wrist-loading position and identifies anatomic abnormalities in the wrist using magnetic resonance imaging (MRI). Methods A retrospective chart review was performed comparing MRI of patients who complained of dorsal wrist pain while performing weight bearing in a wrist extension position with a control group of patients who complained of ulnar-sided wrist pain. The primary MRI outcome was dorsal wrist pathology, including occult dorsal ganglion cyst, scapholunate ligament tear or degeneration, and dorsal capsulitis. Results Dorsal wrist pathology was significantly more prevalent in patients with dorsal wrist pain (84%) than in the patient cohort with ulnar-sided wrist pain (12%). Occult dorsal ganglion cysts were the most common sources of pathology (76%). Conclusion MRI demonstrated an identifiable dorsal abnormality in 84% of patients with dorsal wrist pain associated with weight bearing on the extended wrist. Occult dorsal ganglion cysts are the most common cause of dorsal wrist pain, followed by partial scapholunate tears. When patients complain of dorsal wrist pain during specific extended loading wrist positions such as push-ups, yoga, or Pilates poses, an MRI may be warranted to help identify anatomic abnormalities that may help guide treatment choices. Level of Evidence Diagnostic, Level III.

✓ Despite their benign histological appearance and the current literature composed primarily of case reports with favorable outcomes, ganglion cysts involving peripheral nerves (GCPNs) can cause permanent neurological deficits. The authors present a 27-year Louisiana State University Medical Center (LSUMC) experience with the surgical management of GCPNs. From 1968 to 1995, 27 patients were surgically treated for 27 cysts that involved nerves at nine locations. Cysts of the peroneal nerve were the most common, comprising 52% of the cases. Motor deficit, pain, and sensory changes were present in 83%, 78%, and 48% of cases, respectively. A history of acute trauma was noted in 22%. The mean follow-up duration in these cases was 61 months. Motor recovery was good in only 58% of cases and was related to the severity of the preoperative motor deficit. Pain resolved or was significantly improved in 89% of cases. Five patients underwent nine procedures before referral to LSUMC for treatment of recurrence of their ganglion cysts. None of these patients suffered recurrence after undergoing surgery at LSUMC. However, four additional patients (17%) experienced a total of six recurrences after undergoing their initial procedure. The mean time to recurrence for the patient group as a whole was 16 months. On the basis of their experience, the authors conclude that GCPNs can behave in an aggressive fashion. Patients should be counseled preoperatively about the potential for limited motor recovery and a significant chance for recurrence.

Abstract Background: The current treatments of wrist ganglion have considerable recurrence rate, we developed a new treatment for ganglion cysts in our clinical practice, which combined acupotomy with crisscross thread method, so we now to compare the clinical effectiveness of Chinese acupotomy and crisscross thread with aspiration followed by injection of steroid and open excision for ganglion cysts treatment. Methods: Recruited patients with wrist ganglion were divided into three groups according to the treatments. Among them, 27 patients who were treated by a new combined treatment of Chinese acupotomy and crisscross thread method in group A, 30 patients who were treated by aspiration followed by steroid injection in group B, and 28 patients who were treated by open excision in group C. The data of age, gender, weight, size of ganglion cysts, visual analogue scale (VAS) , cost were recorded and compared by One-way analysis of variance, followed by an LSD (Least Significant Difference)test. The recurrence rates were recorded were analysed by chi-square test.Results: At the first day and one week after treatment, VAS score of group A was similar to group B with no statistic difference. VAS score of group C was higher than group A and B with statistic difference. Six months later, there was no statistic difference among the three groups about VAS. The recurrence rate was 3.7% in group A and 36.7% in group B and 10.7% in group C. No patient infected in three groups. The cost of group A was more than group B with no statistic difference. The cost of group A was much less than group C with statistic difference.Conclusions: The combination of Chinese acupotomy and crisscross thread method was a simple, economical and effective procedure for wrist ganglion cysts.

Background Ganglion cysts are the most frequent soft tissue tumor encountered in the upper extremity and are commonly treated by aspiration or by surgical excision. Ultrasound is a promising addition to traditional aspiration, as it allows for visualization of the needle within the ganglion before aspiration. Questions Are ganglion cysts of the wrist less likely to reoccur if they are aspirated under ultrasound guidance versus “blind” aspiration without the use of ultrasound guidance? Does patient functionality change based on whether or not the cyst recurred? Patients and Methods In total, 52 patients were successfully contacted and recurrence rates were compared between those whose cyst was treated with ultrasound-guided (13 patients) with those whose cyst was treated with blind aspiration (39 patients). Mean follow-up time was 2.9 years. Results Recurrence rates were 69% (9 patients) and 74% (29 patients) for the ultrasound-guided and blind aspiration groups, respectively (p-value: 0.73), showing no significant difference in recurrences of wrist ganglion between the two groups. A metric of functionality (Quick–DASH [Disabilities of the Arm, Shoulder, and Hand]) revealed worse outcomes in patients who experienced return of ganglion cyst after aspiration versus those who did not. Conclusion Additional studies with improved sample sizes are needed to demonstrate the superiority of ultrasound-guided aspiration versus blind aspiration. Due to a high recurrence rate following aspiration (both ultrasound-guided and blinded), a lower threshold for surgical intervention is likely reasonable. Level of Evidence This is a Level IIIb study.

Intra-articular ganglion cysts of the knee joint are rare and most frequently are an incidental finding on MRI and arthroscopy. Most of the previous studies have reported a single ganglion cyst in the knee. There have been previous reports of more than one cyst in the same knee but not in the same structure within the knee. We are reporting a case of dual ACL (anterior cruciate ligament) ganglion cysts one of which was missed on radiological examination but later detected during arthroscopy. To the best of our knowledge, no such case has been reported in the indexed English literature till date.

Osteoid osteoma is a benign bone-forming tumor with hallmark of tumor cells directly forming mature bone. Osteoid osteoma accounts for around 5% of all bone tumors and 11% of benign bone tumors with a male predilection. It occurs predominantly in long bones of the appendicular skeleton. According to Musculoskeletal Tumor Society staging system for benign tumors, osteoid osteoma is a stage-2 lesion. It is classified based on location as cortical, cancellous, or subperiosteal. Nocturnal pain is the most common symptom that usually responds to salicyclates and non-steroidal anti-inflammatory medications. CT is the modality of choice not only for diagnosis but also for specifying location of the lesion, i.e. cortical vs sub periosteal or medullary. Non-operative treatment can be considered as an option since the natural history of osteoid osteoma is that of spontaneous healing. Surgical treatment is an option for patients with severe pain and those not responding to NSAIDs. Available surgical procedures include radiofrequency (RF) ablation, CT-guided percutaneous excision and en bloc resection.
