Unicameral bone cyst of the patella in a young dog

SummaryThis report describes a case of a solitary unicameral patellar bone cyst in a young dog. A five-month-old, male Dobermann Pinscher dog was referred for a 10-day left hindlimb lameness. A mild swelling of the peripatellar soft tissues of the left patella was detected upon physical examination. Signs of pain were elicited upon direct palpation of the patella. Radiographic examination revealed an oval radiolucency within the medullary cavity at the base of the left patella. Radiographic examination, arthroscopy, and histopathology findings supported the diagnosis of a benign patellar bone cyst. The condition was treated by surgical curettage and autogenous bone graft harvested from the ipsilateral proximal tibia. Clinical signs, including lameness and signs of pain upon deep palpation, disappeared three weeks after surgery. Follow-up re-evaluation five years after surgery revealed no recurrence of the cyst and the patient was asymptomatic.

Careful Physical Examination

There are several reasons for a roentgenographic examination of the suspected child abuse victim, including radiographic confirmation and evaluation of obvious trauma for purposes of medical management as well as diagnosis; screening to identify clinically silent, recent injury or evidence of prior injury; and to provide a baseline for comparison with follow-up films. Under no circumstances should a radiographic examination be a substitute for a careful physical examination. Assuming that all areas of the child's body where clinical signs can be found have been examined, what constitutes a necessary and sufficient roentgenographic examination to complement the medically indicated examination or to identify occult evidence of skeletal injury where clinical signs are lacking?

Abstract Background: Fibrous dysplasia and Simple bone cyst are all common benign lesions. A case of osteosarcoma developing from fibrous dysplasia in combination with unicameral bone cyst will be discussed. The radiologic, histologic characteristics and clinical prognostic of the patient will be described. As far as we know, this is the first case report of malignant transformation secondary to fibrous dysplasia in combination with unicameral bone cyst, which is extremely rare and worthy of clinical attention or vigilance. Case presentation: This study describes a case of a 20-years-old male who suffered a 7-years history of intermittent pain in his right proximal tibia, obvious after activity and progressively worsening. Clinical symptoms and imaging examination were consistent with the characteristics of benign primary bone tumor. He underwent a successful curettage operation. Pathological diagnosis was fibrous dysplasia in combination with unicameral bone cyst. After the curettage surgery, the pain in his right knee quickly disappeared and function activities returned to normal during a regular follow-up postoperative. However, He was diagnosed with a recurrence of fibrous dysplasia in combination with unicameral bone cyst and osteosarcoma malignant transformation by chief complaint symptoms of pain and swelling in the right proximal tibia, adequate imaging examination, and pathological diagnosis at 2 years follow-up. Then the patient undergo a limb salvage with tumor prosthesis reconstruction of the right knee. Unfortunately, multiple and unresectable lymph nodes distant metastases happened even with two weeks localized inguinal radiotherapy treatment and one course of neoadjuvant chemotherapy monthly. He eventually received cancer hospice care and died eight months after the diagnosis as malignant transformation and systemic multiple organ metastasis.Conclusions: Although malignant transformation of fibrous dysplasia in combination with unicameral bone cyst is very rare, patients with this disease should be monitored and received lifelong follow-up to obtain early detection, diagnosis and treatment to maximize the efficacy of treatment and survival time. The histological and immunohistochemical findings is very important but not enough. Further research is required to clarify the pathogenesis and prevent malignant transformation.

Purpose: Assessment of the functional and oncologic outcomes regarding endoscopic curettage of different benign bone tumor types within variable anatomic locations. Patients and methods: During the period between February 2012 and December 2016, 26 patients with symptomatic intra-osseous benign bony lesions were included. The age ranged from 3 up to 49 years (mean 20), of 14 females and 12 males. The follow-up duration ranged from 26 up to 58 months (mean 41). Functional scoring was done according to the Revised Musculoskeletal Tumour Society Rating Scale. Anatomic locations of the lesions included: 6 cases in the proximal tibia, 6 cases in the distal femur, 4 cases in the calcaneus, 3 cases in the proximal humerus, 3 cases in the distal tibia, 2 cases in the talus, 1 case in the proximal femur, and 1 case in the distal fibula. The procedure used 4 mm 30° scope for endoscopy, and high speed burrs 3.5–5 mm for extended curettage. Autogenous bone grafting was done in 5 cases, and adjuvant material (polymethylmethacrylate) was needed in 7 cases. Results: After exclusion of one case that was lost in the follow-up, the remaining 25 cases showed full functional recovery at a period of 8–12 weeks, and improved mean functional scores from 20.2 to 28.6/30 post-operatively, with p value <0.001 which was considered as a statistically significant result. The oncologic outcome showed 24 cases with adequate healing, while 1 case developed recurrence (aneurysmal bone cyst in the proximal tibia) for which, an open revision surgery was performed. Intra-operative fracture occurred in another case with aneurysmal bone cyst of the proximal femur, which was fixed by flexible nails with complete healing. Conclusion: Endoscopic curettage of different types of intra-osseous benign bony lesions proved to be an effective treatment modality with promising oncologic outcome, improved functional scores, and fast functional recovery.

Abstract Background A traumatic bone cyst is an uncommon nonneoplastic lesion of the jaws that is considered as a “pseudocyst” because of the lack of an epithelial lining. This lesion is particularly asymptomatic and therefore is diagnosed by routine dental radiographic examination as a unilocular radiolucency with scalloped borders, mainly in the posterior mandibular region. The exact etiopathogenesis of the lesion remains uncertain, though it is often associated with trauma. Case presentation We report three Persian cases of traumatic bone cyst with different clinical and radiographic features, and we present a review of the literature to further discuss diagnostic and treatment challenges. Only one of the three patients reported a history of trauma, and despite the usual signs and symptoms of the lesion, extension of the defect to the ramus, swelling of the lingual cortex, and their unusual presence in the anterior mandible were noted in these patients. Conclusions Because features of this cyst can be varied, careful history taking and radiographic evaluation alongside the clinical signs and symptoms have a very significant role in definitive diagnosis, appropriate treatment, and accurate assessment of prognosis.

ABSTRACT The simple bone cyst,or traumatic bone cyst, solitary or idiopathic bone cavity is an intraosseous pseudocyst discovered through a panoramic radiographic examination. Commonly, the SBC is presented as an asymptomatic lesion, radiolucent, unilocular, without cortical expansion, with margins adorning vital tooth roots of the affected region. The literature has recommended that clinical and radiographic aspects of simple bone cyst are quite convincing as to diagnosis, so follow-up through clinical and radiographic examination has been suggested. This case illustrates an exuberant clinical case of simple bone cyst, which was presented as multilocular and expansive lesion in a 7-year-old patient. Surgical exploration was performed because her parents were anxious about the presumptive diagnosis of other more aggressive lesions. The diagnosis of SBC was confirmed. The case was monitored and, after three years, total bone remodeling of the affected area was observed. In conclusion, asymptomatic radiolucent lesions that suggest a strong presumptive diagnosis of a simple bone cyst can be clinically and radiographically monitored. However, clinical variations, as in the present clinical case, require confirmation of the diagnosis, which is performed through exploratory surgery. The establishment of the diagnosis affords the safest approach for both the professional and the patient.

Wide Range

About 55% of spinal tumors are extradural arising from vertebral bodies, epidural and surrounding neural and soft tissues. More than 90% of extradural spinal tumors are metastatic lesions. Extradural spinal tumors are common cause of back pain, sensory motor deficit and sphincters dysfunction. The wide range of lesions and varied clinical profile, make management of spinal extradural tumors a challenging task for any neurosurgeon.Aim of this study is to analyze and discuss the results of extradural spinal tumors after surgical treatment and relevant literature will be reviewed.This is a retrospective study of 36 patients who were operated for spinal extradural tumors between May 1999 and December 2012 in our institute.Follow up period ranged from 3 years to 12 years. Functional neurological outcome was assessed by McCormick's grading. There were 20 male and 16 female and age ranged from 10 to 80 years. 30 patients presented with back pain and 15 had radicular pain. On presentation 18 patients had motor sensory deficit and 15 had sphincters dysfunction. Most common involved level of spines were thoracic followed by cervical and lumbar.Gross total excision of masses were carried out in all cases. Common pathologies were neurofibromas (16), Ewing's sarcoma (7), granulomas (3), metastatic lesions (2), angiolipoma (2), chondroma (2), aneurysmal bone cyst (1), plasmacytoma (1), rabdomyosarcoma (1) and neuroblastoma (1).Out of 14 patients who harbored malignant pathology 12 patients received radio and chemotherapy. Post operative wound infection occurred in 5 patients. Regarding post operative neurological status, 18 patients showed improvement, 6 patients remained same and 12 patients had deteriorated neurology. Tumor recurrence occurred in 15 patients; 12 patients with malignant and 3 patients with benign lesions on follow up period. There was no surgery related mortality, however, 11 patients died during 3 years follow up period due to adverse pathology they were having.Nepal Journal of Neuroscience 13:3-10, 2016

Abstract Background Unicameral bone cyst (UBC) is a benign tumor whose clinical treatments and efficacy are controversial. The purpose of this study was to evaluate the efficacy of the elastic stable intramedullary nail (ESIN), the injection of autologous bone marrow (ABM) and the combination of ESIN and ABM in the treatment of simple bone cyst of children. Methods 83 children with simple bone cyst were analyzed retrospectively. 28 cases were treated with ABM. 28 cases were treated with ESIN. 27 cases were treated with ABM and ESIN. All cases were diagnosed through X-ray, CT or MRI scans. For the suspicious ones, pathological biopsy was performed for an accurate diagnosis. X-ray examinations were carried out for the postoperative follow-up. Capanna criteria for bone cyst was used for the postoperative evaluation of the three methods. Results All the cases accomplished the follow-up. The effective rate of ABM+ESIN group was significantly higher than that of the ABM group (P<0.05), and the cure rates of ESIN group and ABM+ESIN group were higher than that of ABM group (P<0.05, respectively). The cure time in ESIN group was lower than that of the other two groups (P<0.05, respectively). The times for admission were 2.0±0.0 in ESIN group, 5.7±1.9 in ABM group and 4.7±2.4 in ABM+ESIN group (P<0.05 when compared with each other). Conclusions The method of ABM combined with ESIN for children bone cyst has the highest effective and curative rates. For individual method, ESIN has a higher effective rate and curative rate than that of ABM. Meanwhile, it has the fewest hospitalizations.

Source Of Infection

ABSTRACT Most periapical radiolucent lesions associated with infections of the root canal system heal uneventfully after endodontic treatment. However, some cases may require periradicular surgery in order to remove pathologic tissue from the periapical region and simultaneously eliminate any source of infection that could not be removed by orthograde root canal treatment. With an adequate technique, surgery can address these issues, although it may be insufficient in some situations. This report describes the healing process after surgery in two cases with a 12 months follow-up. In these cases, apicoectomy was followed by retrograde sealing with Super EBA (Harry J. Bosworth Company, Illinois, USA). The bone defect was filled with PerioGlas (NovaBone, Austin, TX, USA) and covered with a resorbable Guidor membrane (Sunstar, Foster Ave, Chicago, USA). No intraoperative or postoperative complications were observed. After 24 months of follow-up, the patient showed no clinical signs or symptoms associated with the lesion and radiographic examination showed progressive resolution of radiolucency.

Oesophageal Duplication Cyst

A 7-year-old intact male Rottweiler dog was evaluated for recurrent dysphagia and regurgitation. Physical examination was unremarkable and routine blood works were within normal limits. Computed tomography revealed a defined lesion in the caudal mediastinum arising from the oesophagus. The lesion was excised using intercostal thoracotomy and the histological diagnosis was oesophageal duplication cyst. The dog recovered uneventfully and at a 3-year follow-up no clinical signs were reported. Although extremely rare, oesophageal duplication cysts should be considered in the differential diagnosis in cases of chronic regurgitation and dysphagia associated with evidence of an oesophageal lesion.

This report is of a proximal femoral unicameral bone cyst in a patient presented at 3 years. Intra-lesional steroid injection was used to treat this large active lesion. The response to treatment was monitored with the use of dual-energy X-ray absorptiometry (DXA) scan as an indirect method of monitoring the activity of the bone cyst. The patient had developed stress fracture during the course of treatment which had remodelled fully after successful treatment with multiple injections; at 12-year follow-up, the patient reached skeletal maturity. The affected femur had remodelled back to normal radiological appearance without avascular necrosis. This has demonstrated that steroid injection is a safe and effective procedure to achieve regression of a large active bone cyst in the proximal femur. It is a minimal invasive procedure resulting in no scar. DXA scan is a useful method combining clinical assessment to monitor status of the bone cyst to allow timing of injection.
