Massive osteolysis of the pelvis, femur and sacral bone with a Gorham-Stout syndrome

Massive Axial and Appendicular Skeletal Deformities in Connection with Gorham-Stout Syndrome

: Background: Etiological understanding is the corner stone in the management of skeletal deformities. Methods: Multi-centre study of patients with deformities in connection with diverse etiological backgrounds. We aimed to study four patients (one boy and three girls) with variable axial and appendicular deformities in connection with a vanishing bone disorder. Results: Axial deformities such as scoliosis, kyphoscoliosis, compressed fused vertebrae, appendicular fractures, dislocations, and vicious disorganization deformities of the joints were in connection with the vanishing bone disorder, namely Gorham-Stout syndrome. Conclusions: It is mandatory to establish proper clinical and radiological phenotypic characterization in children and adults presented with unusual skeletal deformities. Identifying the reason behind these deformities is the key factor to draw a comprehensive management plan.

Successful treatment of Gorham-Stout syndrome in the spine by vertebroplasty with cement augmentation: A case report and literature review

RATIONALE

Gorham-Stout syndrome in the spine is extremely rare, and there is no standard curative management thus far. The objective of this article is to report a very rare case of Gorham-Stout syndrome of the lumbar and sacral spine with chylothorax and chyloperitoneum successfully treated by combination of vertebroplasty with cement augmentation and medication treatment. We described the clinical characteristics and postoperative therapy of the patient, and reviewed all of the published cases of Gorham-Stout syndrome of the lumbar and sacral spine.

PATIENT CONCERNS

A 31-year-old man presented with increasingly serious abdominal distention and back pain. MRI showed massive bony destruction of the spine and pelvis. CT and ultrasonography demonstrated massive ascites and mild hydrothorax.

DIAGNOSES

We believe this is the first report of a case of Gorham-Stout syndrome with both chylothorax and chyloperitoneum.

INTERVENTIONS

Chest and abdominal cavity puncture was performed for symptomatic relief and the test results confirmed chylothorax and chyloperitoneum. Tissue biopsy and percutaneous vertebroplasty at L5 were performed and the postoperative pathology together with symptoms and examinations were reported to be consistent with Gorham-Stout syndrome. Subsequently, we administered combination medical treatment consisting of interferon-α-2b, zoledronic acid and calcitriol.

OUTCOMES

At the 1-year and 2-year follow-up visit, he had nearly full complete remission and reported palliative back pain. Moreover, the amount of pleural and peritoneal fluid was successfully reduced gradually.

LESSONS

Vertebroplasty by cement augmentation may be a treatment option for patients with Gorham-Stout Syndrome in the spine who cannot undergo appropriate surgery or decline open surgery. This represents a safe and minimally invasive approach to sustainably relieve pain and stabilize vertebral bodies with Gorham-Stout syndrome in the spine.

From tooth extraction to Gorham-Stout disease: A case report

•

Gorham-Stout disease (GSD) is a very rare idiopathic bone disorder characterised by spontaneous and progressive osteolysis, associated with angiomatous proliferation and soft tissue swelling without new bone formation.

•

The clinical presentation of GSD includes pain, functional impairment, and swelling, although a few asymptomatic cases have been reported, similar to our case.

•

We present this rare case of GSD with several localisations to emphasise that any procedure appearing to be simple can go catastrophically wrong and can result in the discovery of something that is unexpected and extremely rare.

•

We wish to emphasise the extreme rarity of the case, focusing on the large difference between the preoperative panoramic radiograph and whole-body CT and MRI images obtained on the day after the first surgical procedure.

Introduction

Gorham-Stout disease (GSD), or vanishing bone disease, is a very rare condition of unknown aetiology. It is characterised by progressive osteolysis and angiomatosis.

Case presentation

We report the discovery of this very rare disease following a trivial deciduous tooth extraction in a 14-year-old female. We focus initially on the difference between the preoperative orthopantomography and the whole-body computed tomography and magnetic resonance images obtained post-haemorrhage, and then on the improvement of strategies for the correct diagnosis and treatment of this disease.

Discussion

Bone loss and the proliferation of vascular structures can occur in a single bone or spread to soft tissue and adjacent bone; areas commonly affected by GSD include the ribs, spine, pelvis, skull, clavicle, and the maxillofacial area. The clinical presentation of GSD includes pain, functional impairment, and swelling, although a few asymptomatic cases have been reported, similar to our case.

Conclusion

We report a very rare case of this multicentric disease in an asymptomatic child who presented for dental extraction, almost died, and was then diagnosed with and treated for GSD.

Complex single step skull reconstruction in Gorham's disease - a technical report and review of the literature

Background

Gorham’s disease is a rare osteolytic disorder characterized by progressive resorption of bone and replacement of osseous matrix by a proliferative non-neoplastic vascular or lymphatic tissue. A standardized treatment protocol has not yet been defined due to the unpredictable natural history of the disease and variable clinical presentations. No single treatment has proven to be superior in arresting the course of the disease. Trials have included surgery, radiation and medical therapies using drugs such as calcium salts, vitamin D supplements and hormones. We report on our advantageous experience in the management of this osteolyic disorder in a case when it affected only the skull vault. A brief review of pertinent literature about Gorham’s disease with skull involvement is provided.

Case presentation

A 25-year-old Caucasian male presented with a skull depression over the left fronto-temporal region. He noticed progressive enlargement of the skull defect associated with local pain and mild headache. Physical examination revealed a tender palpable depression of the fronto-temporal convexity. Conventional X-ray of the skull showed widespread loss of bone substance. Subsequent CT scans showed features of patchy erosions indicative of an underlying osteolysis. MRI also revealed marginal enhancement at the site of the defect. The patient was in need of a pathological diagnosis as well as complex reconstruction of the afflicted area. A density graded CT scan was done to determine the variable degrees of osteolysis and a custom made allograft was designed for cranioplasty preoperatively to allow for a single step excisional craniectomy with synchronous skull repair. Gorham’s disease was diagnosed based on histopathological examination. No neurological deficit or wound complications were reported postoperatively. Over a two-year follow up period, the patient had no evidence of local recurrence or other systemic involvement.

Conclusions

A single step excisional craniectomy and cranioplasty can be an effective treatment for patients with Gorham’s disease affecting the skull vault only. Preoperative planning by a density graded CT aids to design a synthetic bone flap and is beneficial in skull reconstruction. Systemic involvement is variable in this patient’s population.

Gorham-Stout syndrome in mainland China: a case series of 67 patients and review of the literature

OBJECTIVE

Gorham-Stout syndrome (GSS) is a rare disorder of uncertain etiology and unpredictable prognosis. This study aims to present a comprehensive understanding of this rare entity.

METHODS

A literature search in PubMed and three Chinese databases was performed to screen histologically proven GSS cases among Chinese residents in the mainland. We analyzed the patients' clinical characteristics, the value of different treatment modalities and their influence on the clinical outcome.

RESULTS

Sixty-seven cases were finally enrolled. There were 43 men (64.2%) and 24 women (35.8%). The mean age at diagnosis was 28 years (1.5-71 years). The most common clinical symptoms included pain (n=40, 59.7%), functional impairment (n=13, 19.4%), and swelling (n=12, 17.9%). The radiographic presentation of 37 cases (55.2%) was disappearance of a portion of the bone. The others presented as radiolucent foci in the intramedullary or subcortical regions. A total of 42 cases provided data on therapy, these included surgery (n=27, 40.3%), radiation therapy (n=6, 9.0%), surgery combined with radiation therapy (n=2, 3.0%), and medicine therapy (n=7, 10.4%). For 30 of these 42 cases, follow-up data were available: 21 cases had the disorder locally controlled and 9 had a symptom progression. Fortunately, the disease is not fatal in the majority of cases.

CONCLUSIONS

GSS has no specific symptoms and it should be taken into consideration when an unclear massive osteolysis occurs. The efficacies of different treatment modalities are still unpredictable and further research is required to assess the values of different treatments.

The diagnosis and management of patients with idiopathic osteolysis

Idiopathic osteolysis or disappearing bone disease is a condition characterized by the spontaneous onset of rapid destruction and resorption of a single bone or multiple bones. Disappearing bone disorder is a disease of several diagnostic types. We are presenting three patients with osteolysis who have different underlying pathological features. Detailed phenotypic assessment, radiologic and CT scanning, and histological and genetic testing were the baseline diagnostic tools utilized for diagnosis of each osteolysis syndrome. The first patient was found to have Gorham-Stout syndrome (non-heritable). The complete destruction of pelvic bones associated with aggressive upward extension to adjacent bones (vertebral column and skull base) was notable and skeletal angiomatosis was detected. The second patient showed severe and aggressive non-hereditary multicentric osteolysis with bilateral destruction of the hip bones and the tarsal bones as well as a congenital unilateral solitary kidney and nephropathy. The third patient was phenotypically and genotypically compatible with Winchester syndrome resulting in multicentric osteolysis (autosomal recessive). Proven mutation of the (MMP2-Gen) was detected in this third patient that was associated with 3MCC deficiency (3-Methylcrontonyl CoA Carboxylase deficiency). The correct diagnoses in our 3 patients required the exclusion of malignant osteoclastic tumours, inflammatory disorders of bone, vascular disease, and neurogenic arthropathies using history, physical exam, and appropriate testing and imaging. This review demonstrates how to evaluate and treat these complex and difficult patients. Lastly, we described the various management procedures and treatments utilized for these patients.

Retrospective French nationwide survey of childhood aggressive vascular anomalies of bone, 1988-2009

OBJECTIVE

To document the epidemiological, clinical, histological and radiological characteristics of aggressive vascular abnormalities of bone in children.

STUDY DESIGN

Correspondents of the French Society of Childhood Malignancies were asked to notify all cases of aggressive vascular abnormalities of bone diagnosed between January 1988 and September 2009.

RESULTS

21 cases were identified; 62% of the patients were boys. No familial cases were observed, and the disease appeared to be sporadic. Mean age at diagnosis was 8.0 years [0.8-16.9 years]. Median follow-up was 3 years [0.3-17 years]. The main presenting signs were bone fracture (n = 4) and respiratory distress (n = 7), but more indolent onset was observed in 8 cases. Lung involvement, with lymphangiectasies and pleural effusion, was the most frequent form of extraosseous involvement (10/21). Bisphosphonates, alpha interferon and radiotherapy were used as potentially curative treatments. High-dose radiotherapy appeared to be effective on pleural effusion but caused major late sequelae, whereas antiangiogenic drugs like alpha interferon and zoledrenate have had a limited impact on the course of pulmonary complications. The impact of bisphosphonates and alpha interferon on bone lesions was also difficult to assess, owing to insufficient follow-up in most cases, but it was occasionally positive. Six deaths were observed and the overall 10-year mortality rate was about 30%. The prognosis depended mainly on pulmonary and spinal complications.

CONCLUSION

Aggressive vascular abnormalities of bone are extremely rare in childhood but are lifethreatening. The impact of anti-angiogenic drugs on pulmonary complications seems to be limited, but they may improve bone lesions.

Gorham-Stout syndrome in a male adolescent-case report and review of the literature

Gorham-Stout syndrome is a rare disease characterized by vascular proliferation in the bones, effecting osteolysis. When it is complicated by chylothorax, the prognosis is poor. The present case illustrates successful management of chylothorax by a combination of surgery (thoracic duct ligation and excision of lymphangiomatous tissue combined with pleurodesis) and treatment with alpha-2b interferon. Treatment in 38 published cases is reviewed.

Gorham's disease or massive osteolysis

Gorham's disease is a rare disorder characterized by proliferation of vascular channels that results in destruction and resorption of osseous matrix. Since the initial description of the disease by Gorham and colleagues (1954) and by Gorham and Stout (1955), fifty years have elapsed but still the precise etiology of Gorham's disease remains poorly understood and largely unknown. There is no evidence of a malignant, neuropathic, or infectious component involved in the causation of this disorder. The mechanism of bone resorption is unclear. The clinical presentation of Gorham's disease is variable and depends on the site of involvement. It often takes many months or years before the offending lesion is correctly diagnosed. A high index of clinical suspicion is needed to arrive at an early, accurate diagnosis. Patients with Gorham's disease may complain of dull aching pain or insidious onset of progressive weakness. In some cases, pathologic fracture often leads to its discovery. Gorham's disease is progressive in most patients; however, in some cases, the disease process is self-limiting. The clinical course is generally protracted but rarely fatal, with eventual stabilization of the affected bone being the most common sequelae. Chylous pericardial and pleural effusions may occur due to mediastinal extension of the disease process from the involved vertebra, scapula, rib or sternum, and can be life threatening. A high morbidity and mortality is seen in patients with spinal and/or visceral involvement. The medical treatment for Gorham's disease includes radiation therapy, anti-osteoclastic medications (bisphosphonates), and alpha-2b interferon. Surgical treatment options include resection of the lesion and reconstruction using bone grafts and/or prostheses. In most cases, bone grafts tend to undergo resorption and are not helpful. Surgical reconstruction and/or radiation therapy are used for management of patients who have large, symptomatic lesions with long-standing, disabling functional instability. Surgical stabilization may be required for unstable spinal lesions. Various treatment options, including pleurectomy, pleurodesis, thoracic duct ligation, radiation therapy, interferon therapy, and bleomycin, have been used for management of patients with Gorham's disease presenting with chylothorax. In general, no single treatment modality has proven effective in arresting the disease.

Massive Gorham-Stout syndrome of the pelvis

Gorham-Stout disease is defined as a spontaneous, massive, and nonfamilial idiopathic osteolysis. The diagnosis is based essentially on radiological and histological findings. Biopsy reviews always reveal excessive intraosseous nonmalignant proliferation of small vessels, which results in bone resorption and may extend to adjacent bones and soft tissues. These lesions are progressively replaced by extensive fibrosis. Since its first description in 1955, there is still controversy about its prognosis, etiology, and treatment. A case of Gorham-Stout disease, located on the right pelvis, is reported with 50 years of clinical and radiographic follow-up, in a man who has never been treated. To date, this is the longest documented case report of the disease and its rare natural history. It demonstrates that after a variable time of evolution, the massive osteolysis is able to undergo spontaneous arrest and that the lesions may remain stable during several decades. Besides, no reossification was observed, even after 37 years of disease quiescence. Based on a large review of the literature, the authors then discuss the prognosis, etiopathology, and different therapeutic options available to halt the progression of the osteolysis.

Gorham Disease of the Spine: A Case Report and Treatment Strategies for This Enigmatic Bone Disease

Gorham disease is an extremely rare condition of unknown etiology characterized by progressive osteolysis. Only 28 cases of its spinal involvement have been reported, and some of those cases showed kyphosis, kyphoscoliosis, subluxation or dislocation. No definite regimen of treatment has been established yet. A 10-year-old boy presented with a severe and progressive kyphosis over 90 degrees caused by Gorham disease from T3 to T12. In situ posterior fusion with a hook and rod system and iliac bone grafts were performed, but after surgery, he had complete paraplegia and its cause was uncertain. Based on the unfortunate consequence of the present case and the review of the literature, we propose the treatment strategies for spinal Gorham disease.

Ongoing osteolysis in patients with lymphangioma

Severe osteolysis is a rare complication of lymphangioma. It can progress despite treatment and may be fatal. Four patients presented with massive osteolysis and serious related complications. Of these, two responded well to OK-432 therapy with arrest of the osteolysis. Complete recovery from life-threatening pleural effusion has been noted in one. Of the two nonresponders, one died of progressive osteolysis of the cervical and occipital bones, the other, despite therapy, still shows progressive osteolysis of the left leg from the femur to the phalanges. A boneless leg may be the outcome.
