Perhaps the later type may arise from primary intramedullary metaplasia [12]. Helpful, trusted answers from doctors: Dr. Placik on intraosseous ganglion: Yes...In fact this used to be a treatment many years ago -- smack it with a bible! Among the 17 cases, 6 (40%) were in weight-bearing long bones of the lower limb. Clin Imaging. Review articles are excluded from this waiver policy. The presence of intracarpal cystic lesions should be considered in the differential diagnosis of wrist pain. On magnetic resonance imaging a cystic lesion of the proximal humerus was detected. Ganglion Cyst Symptoms Symptoms of a ganglion cyst can include: A soft bump or mass that changes size but doesn’t move. In some cases the lesion arises adjacent to an area of repeated osseous microtrauma. 38 (6):379-81. . Synovial fluid intrusion is the currently favored pathological mechanism of soft-tissue ganglion [12]. Intraosseous ganglion is a benign, nonneoplastic bone lesion with histological similarity to that in soft tissue [1–3]. Introduction Intraosseous ganglions are rare, benign lesion of bone that most frequently occur in the metaphyses of the long bones. However, chondroblastomas tend to occur in younger patients. Clinical data are summarized in Tables 1 and 2. 6). Intraosseous ganglion is a cystic lesion that contains gelatinous material and is regarded as similar to that of soft-tissue ganglion. They most often occur at the back of the wrist, followed by the front of the wrist. Therefore, it seems much more likely that primary bone lesions will spread to the soft tissues. Background. The plain radiographs showed a lesion with marginal osteosclerosis. A 70-year-old female presented with a complaint of pain to the right dorsal forefoot. Scand J Plast Reconstr Surg Hand Surg. Tuzuner T: Penetrating type intraosseous ganglion cyst of the lunate bone. The average age of patients with an intraosseous ganglion in the long bone was 51.4 years, which was not significantly different from that of patients with an intraosseous ganglion in a flat bone (47.3 years) or in a small bone (45.0 years). Discussion and Conclusion. Histologically, arthritic cysts. The average size of an intraosseous ganglion overall was 22.4 mm (range, 6–40 mm); in long bones was 23.7 mm; in flat bones was 31.3 mm; and in small bones was 10.8 mm. Clinical summary of intraosseous ganglion. The most common carpal lesion is the intra-osseous ganglion (IOG). All lesions occurred at the epiphysis or near the joint. No statistically significant difference was found in the size of lesions by bone type. A clinical-pathological report on 42 cases,”, C. Kambolis, P. G. Bullough, and H. I. Jaffe, “Ganglionic cystic defects of bone,”, I. J. F. Uriburu and V. D. Levy, “Intraosseous ganglia of the scaphoid and lunate bones: report of 15 cases in 13 patients,”, J. Malghem, B. C. Vande Berg, C. Lebon, F. E. Lecouvet, and B. E. Maldague, “Ganglion cysts of the knee: articular communication revealed by delayed radiography and CT after arthrography,”. Intraosseous ganglia located in the scaphoid have rarely been described in the literature. They are mostly benign lesions; however, not all hypoechoic or T2 hyperintense lesions are cysts, and neoplastic lesions may be missed if close attention is not paid to the typical imaging findings. IOG may cause symptoms localized to the affected bone, and should be considered in the setting of pain without another clinical explanation. Giant cell tumor of bone and aneurysmal bone cyst are typically large and can be differentiated from intraosseous ganglion on radiographs by a lack of marginal osteosclerosis and thinning of the adjacent cortex due to expansion. The pathogenesis is unknown, but intraosseous ganglion does not appear to be associated with either soft-tissue ganglion or with osteoarthritis. A retrospective medical record review showed that 17 patients (8 men, 9 women) with a final diagnosis of an intraosseous ganglion were seen at our institute during the 6 years from 2004 to 2009. Akio Sakamoto, Yoshinao Oda, Yukihide Iwamoto, "Intraosseous Ganglia: A Series of 17 Treated Cases", BioMed Research International, vol. Also known as a subchon-dral bone cyst, the IOG is a benign, mucin-filled, cystlike lesion that arises within the subchondral medullary bone. Intraosseous ganglion cysts are rare. The main presenting symptom is radial wrist pain that usually resolves after treatment. sheath. Conclusions: Scaphoid cystic lesions are most commonly intraosseous ganglia, but can include other etiologies as well. Darcy PF, Sorelli PG, Qureshi F, Orakwe S, Ogufere W. Carpal tunnel syndrome caused by an intraosseous ganglion of the capitate. Intraosseous ganglion does not appear to be associated with either soft-tissue ganglion or with osteoarthritis. Intraosseous ganglion cysts may also form at this ligament’s bony attachments. Symptomatic IOGs are successfully treated with curettage and bone grafting [3-5,7,10]. Ganglion: Symptoms. Ganglion cysts most commonly develop along the tendons or joints of your wrists or hands. G. R. FISK, “Bone concavity caused by a ganglion,”, W. A. Crabbe, “Intra-osseous ganglia of bone,”, F. Feldman and A. Johnston, “Intraosseous ganglion,”, F. Schajowicz, M. Clavel Sainz, and J. Sometimes, hip cysts may develop as a result of a spread of disease from somewhere else, but this is not common. One of the more common imaging findings when evaluating the knee, whether by ultrasound or MRI, is the cystic lesion. All cases were introduced, and during this time, all suspected intraosseous ganglion lesions were treated as an extension of biopsy. Regardless of the etiology, the ganglion wall is composed of fibrous, collagenous fibers with mu-coid-degeneration and no clear epithelial or synovial cell lining. Peak incidence of intraosseous ganglion is in the 4th and 5th decades of life, and it is rare in children [5, 6]. Intraosseous ganglion cysts are benign lesions located in the subchondral bone adjacent to the joint and are usually found in adults [1]. A P value of less than 0.05 was considered to indicate statistical significance. Carpal intraosseous ganglia are one of the rarely seen pathologic conditions in the hand. Lesions may occur in multiple carpal bones, and may be bilateral [3,9,10]. No recurrence was observed in any case after at least 3 years of followup. The initial diagnosis of intraosseous ganglion was made based on the plain radiographs. Intraosseous ganglia are benign, non-neoplastic lesions of bones that are histologically similar to their soft tissue equivalents. 2. Intraosseous ganglion is a cystic lesion that contains gelatinous material, most often occurs in middle-aged patients, and is regarded as similar to soft-tissue ganglion. However, the reported frequency of extraosseous extension is only 16% [5] and was 24% in the current series. RESULTS: Of these 17 patients, intraosseous ganglion cysts were diagnosed in 15. Symptomatic cyst usually present with diffuse dorsal wrist pain or ulnar sided wrist pain and mimic Kienbock disease. Usually ganglion cysts do not require to be treated if they do not produce any symptoms. These cystic lesions may be related to bursae, cysts, or other cyst-like lesions and could be soft tissue or intraosseous in origin. The authors make a generous window to completely evacuate the ganglion contents and, more importantly, the ganglion wall. There is less association between intraosseous ganglia and degenerative joint disease than previously reported. Differentiation from chondroblastoma can be difficult, as the lesion typically has marginal osteosclerosis. There was communication between an IOGs are regularly seen on wrist radiographs obtained to evaluate wrist pain or other problems. Intraosseous ganglion contains mucoid viscous material with no epithelial or synovial lining [4]. Intraosseous ganglia are well-circumscribed and generally do not have an identifiable macroscopic penetration of the cortex. Allograft bone or bone substitutes may also be used. 2008 Jan-Feb. 32 (1):73-6. All authors read and approved the final paper. Shape and size. Location. The authors declare no conflict of interests. A synovial leak may occur with focal avascular necrosis and subsequent ganglion formation (Fig. Intraosseous ganglion cysts can be occasionally be symptomatic, but a symptomatic ganglion cyst is a diagnosis of exclusion. Patients with this disorder are usually middle aged and present with mild, localized pain that is increased by weight bearing. A clinicopathological study of eighty-eight cases,”, D. A. Confirmation of the cystic nature of the lesion by gadolinium enhancement may be helpful for diagnosis of an intraosseous ganglion by lack of enhancement. Onset is often over months. An intraosseous ganglion is considered to be a lesion that is distinct from a degenerative subchondral cyst [4]. Intraosseous ganglia are benign cystic and often multiloculated lesions composed of fibrous tissue with extensive mucoid changes located in the subchondral bone adjacent to a joint. In some rare cases, the cyst can develop due to other reasons. This report describes a case of an intraosseous ganglion of the proximal humerus. 5). An intraosseous ganglion (plural: ganglia) is a benign subchondral radiolucent lesion without degenerative arthritis. Intraosseous ganglia are identified most often in middle-aged patients. However, if the cyst is inside the shoulder joint certain tests such as ultrasound, MRI, may be required for its diagnosis. Nonoperative observation is an option for intraosseous ganglia [1]. 4) [11]. Ganglion cysts that cause pain or affect the nerve should be removed through aspiration or surgery. J Hand Surg 22B:820-1,1997. J Hand Surg 17B:429-32,1992. In the current study, because almost all cases of an intraosseous ganglion were treated surgically, the clinical data regarding the anatomical site and ages appear to be accurate. Patient age and lesion size were statistically analyzed using the Mann-Whitney U test. Results. The next most common locations are the ankles and feet. On plain radiographs, the intraosseous ganglion appears as a well-defined osteolytic lesion located near a joint. Report of four cases and review of the literature,”, U. Helwig, S. Lang, M. Baczynski, and R. Windhager, “The intraosseous ganglion. Natural Autoimmune Diseases Cure and Treatment. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. On imaging studies, they present as well-demarcated uniloculated or multiloculated lytic defects with a thin rim of sclerotic bone. This type of communication has also been seen in imaging of an intraosseous ganglion, which was presumably of articular origin [3]. The prevalence of intraosseous ganglia has been reported to have a small male preponderance [7], but no significant difference based on sex was seen in the current series. Ganglion cysts are round or oval and usually measure less than an inch (2.5 centimeters) in diameter. Fracture was present in 3 of the 17 cases (18%): one in the scaphoid bone and 2 in the ilium, the latter comprising 2 of the 2 ilia (100%). Surgery is recommended when symptoms, such as pain, are present, and in growing intraosseous cysts, which can cause complications, including fractures. Treatment For Ganglion Cyst In Shoulder. The etiology is unknown, but association with degenerative joint disease has been considered. IGC is not uncommon in the carpal bones. Copyright © 2013 Akio Sakamoto et al. Intraosseous ganglion are rarely reported and occur mainly as carpal bone cysts.1,2,3,4 A ganglion cyst of the lateral malleolus is a rare occurrence with only one report in the literature.5 We report a case of an intraosseous ganglion of the lateral malleolus with soft tissue swelling. Kligman M, Roffman M: Bilateral intraosseous ganglia of the scaphoid and lunate bones. They are also frequent incidental findings in the capitate, arising volarly at the attachment of the radioscaphocapitate ligament. Bone grafting was performed in all the curetted lesions except for one metacarpal lesion. Grafting restores the native architecture of the bone, and may expedite healing and pain relief postoperatively. The etiology of intraosseous ganglion is unknown. In the current case series, an obvious continuity to the nearby joint was not observed in many cases. Adjacent to synovial lined joint structures and cartilage surfaces knowledge of the lunate bone the attachment of the ligament.
