Abstract
BACKGROUND Pediatric Langerhans cell histiocytosis (LCH) often results in vertebral compression fracture. However, few reports have reported vertebral remodeling during the course of LCH. We aimed to investigate the longitudinal reconstitution and transformation of the affected vertebrae and the adjacent structures in young children with spinal LCH. METHODS We recruited 13 patients, including 16 affected vertebrae, diagnosed with LCH via biopsy. The average age at first visit was 3.6 years. The average follow-up period was 10.2 years. Vertebral lesions involved L2 in 3 cases; T12, L1, or L5 in 2 cases; and C4, C5, C7, T5, T8, T9, or L3 in 1 case. We measured the ratios of the height of the affected vertebra and 1 vertebra above the affected one to that of the second vertebra above the affected one, local kyphotic angles, and the ratio of the height of the center of the adjacent disk to that of one disk above it. RESULTS The collapse of the affected vertebra was most severe after 1 year of disease onset. The rate of reconstitution accelerated at 2 years or later of disease onset. The recovery speed of the anterior wall was faster than that of the center height. While the height of the affected vertebrae was restored, the thickness of the adjacent disk also increased. Further, the height of the adjacent vertebrae increased in a similar manner. The average local kyphosis angle shifted to lordosis within the first 3 years. CONCLUSIONS The heights of not only the disk but also the adjacent vertebra increased during the vertebral collapse phase in pediatric spinal LCH patients. These transformations may affect the realignment of the sagittal spinal balance at the earlier stage of the disease. During the collapse phase, the heights of the adjacent vertebrae and disks increase but after the affected vertebrae reconstituted, the augmentation of adjacent vertebrae and disks diminished. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND Langerhans cell histiocytosis (LCH) in adult lumbar spine is extremely rare, and optimal treatments remain unclear. In literature, only a few cases of lumbar spine LCH were treated using surgery but en bloc vertebral resection has not been used. CASE PRESENTATION A 50-year-old man presented with unbearable radiating pain at his right leg. Radiological studies revealed a solitary osteolytic lesion, which was moderately enhanced on contrast MR imaging and hyper-metabolic on PET/CT, at the right L5 vertebral body and arch. In biopsy, Langerhans cells were observed, but findings were insufficient to establish a diagnosis of LCH. A modified L5 en bloc vertebral resection via anterior and posterior approaches was performed to remove the right 2/3 portion of the L5 vertebra. The left 1/3 vertebral body and left pedicle of L5, which were not affected, were kept in situ to allow short instrumentation and reconstruction. His leg pain disappeared after the surgery, and a precise diagnosis of LCH was established after a throughout histological study of the removed vertebra. The patient further accepted 1 cycle of low-dose radiotherapy postoperatively. At 18-month follow-up, the lumbosacral spine was fused and no local reoccurrence was noticed. CONCLUSIONS For lumbar spine LCH, surgery should be considered if there are neurological symptoms or histological diagnosis is indefinite in biopsy. En bloc vertebral resection can be used to alleviate neurological symptoms and prevent local reoccurrence.

Abstract
PURPOSE The eosinophilic granuloma is a unifocal or multifocal Langerhans cell histiocytosis characterized by an expanding proliferation of Langerhans cells in bones. Skeletal LCH is a rare condition, and vertebral regeneration in cases of vertebral body collapse is even rarer. We report the case of a girl with spontaneous complete healing. METHODS AD RESULTS A 3-year-old girl was referred for nighttime back pain, with no fever and no neurologic signs. Within a few days, she developed sudden painful restriction of all spine movements. X-ray and computed tomography (CT) of the spine showed reduced T7 vertebral body height (vertebra plana).The patient underwent T7 curettage and the histopathological exam was suggestive of LCH. Two additional skull lesions were found and therefore she underwent chemotherapy. After 7 years of follow-up, total vertebral reconstruction was observed. CONCLUSIONS Despite the rarity of the condition and despite the rarity of vertebral body lesion resolution, total vertebral body reconstruction was observed over a 7-year period. Long-term follow-up is necessary for a better understanding of the final outcome of patients with EG.

Abstract
Introduction Langerhans cell histiocytosis (LCH) occurs rarely in the spine of adults. The radiological findings usually resemble vertebral tumors. Etiology of LCH has not been clearly established yet. Therapeutic approaches are still controversial. We describe a case of LCH in an adult spine. Case description A patient who presented with low back pain had an osteolytic lesion in the L1 vertebral body without neurological deficits, and fluoroscopy-guided needle biopsy of the L1 vertebral body was performed. The immunohistochemical diagnosis confirmed LCH. The patient was successfully treated with conservative methods. Discussion The choice of appropriate therapy is very important, with treatment options varying from watch-and to aggressive treatment. Conclusion LCH is considered as a pediatric disease that is extremely rare in the spine of adults and should be include in the differential diagnosis of osteolytic vertebral lesions. Conservative treatment is best choice for a patient with LCH without neurological deficit or spinal instability.

Abstract
Vertebral collapse is a significant event in the paediatric patient with a real potential for associated deformity and morbidity. While in adults the causes tend towards the malignant, particularly metastatic and metabolic disease, the paediatric population demonstrates a different range of diagnoses. This article reviews the typical imaging findings of the more common underlying acquired pathological causes of vertebral collapse in children, including Langerhans cell histiocytosis, chronic recurrent multifocal osteomyelitis, osteogenesis imperfecta. Other causes include pyogenic osteomyelitis and tuberculosis and neoplastic lesions, either primary, metastatic or of haematological origin.

Abstract
Langerhans cell histiocytosis (LCH), a disorder of the phagocytic system, is a rare condition. Moreover, spinal involvement causing myelopathy is even rare and unusual. Here, we report a case of atypical LCH causing myelopathy, which was subsequently treated by corporectomy and fusion. An 8-year-old boy presented with 3 weeks of severe neck pain and limited neck movement accompanying upper and lower limbs motor weakness. CT scans revealed destruction of C5 body and magnetic resonance imaging showed a tumoral process at C5 with cord compression. Interbody fusion using anterior cervical plate packed by autologus iliac bone was performed. Pathological examination confirmed the diagnosis of LCH. After the surgery, the boy recovered from radiating pain and motor weakness of limbs. Despite the rarity of the LCH in the cervical spine, it is necessary to maintain our awareness of this condition. When neurologic deficits are present, operative treatment should be considered.

Abstract
To stress the clinical and radiologic presentation and treatment outcome of Langerhans cell histiocytosis (LCH) with multiple spinal involvements. A total of 42 cases with spinal LCH were reviewed in our hospital and 5 had multifocal spinal lesions. Multiple spinal LCH has been reported in 50 cases in the literature. All cases including ours were analyzed concerning age, sex, clinical and radiologic presentation, therapy and outcome. Of our five cases, three had neurological symptom, four soft tissue involvement and three had posterior arch extension. Compiling data from the eight largest case series of the spinal LCH reveals that 27.2% multiple vertebrae lesions. In these 55 cases, there were 26 female and 29 male with the mean age of 7.4 years (range 0.2-37). A total of 182 vertebrae were involved including 28.0% in the cervical spine, 47.8% in thoracic and 24.2% in the lumbar spine. Extraspinal LCH lesion was documented in 54.2% cases, visceral involvement in 31.1% and vertebra plana in 50% cases. Paravertebral and epidural extension were not documented in most cases. Pathological diagnosis was achieved in 47 cases including 8 open spine biopsy. The treatment strategy varied depending on different hospitals. One patient died, two had recurrence and the others had no evidence of the disease with an average of 7.2 years (range 1-21) of follow-up. Asymptomatic spinal lesions could be simply observed with or without bracing and chemotherapy is justified for multiple lesions. Surgical decompression should be reserved for the uncommon cases in which neurologic compromise does not respond to radiotherapy or progresses too rapidly for radiotherapy.

Abstract
STUDY DESIGN A retrospective study of cervical Langerhans cell histiocytosis (LCH). OBJECTIVE To evaluate the safety and efficiency of the present diagnosis and treatment strategy. SUMMARY OF BACKGROUND DATA The diagnosis and treatment protocols are still controversial for the rarity of cervical LCH. METHODS Thirty patients with cervical LCH were diagnosed in the past 10 years. Biopsy was routinely performed to establish the final diagnosis before treatment. Immobilization was usually the first choice. Low-dose radiotherapy was suggested for cases with solitary marked bony erosion and/or soft tissue extension, and chemotherapy for cases with multiple lesions. Surgery was preserved for suspected malignancy, neurologic deficits, severe deformity, and/or instability. RESULTS The mean age at diagnosis was 14.2 (range: 1.5-41) years old. Neck pain (96.7%) was the most common symptom, followed by restricted motion (70%), neurologic symptoms (36.7%), and torticollis (30%). Four cases had multiple lesions. Fourteen cases had atlantoaxial lesion and 16 cases were subaxial. The lesion extended to paravertebral soft tissue in 40% cases, to epidural space in 30%, to pedicle and/or transverse process in 56.3%. One case had endplate destruction. The accuracy of percutaneous needle biopsy under CT guidance was 91.2%. Eighteen patients had conservative treatment and 12 underwent operation. Three cases involving C2 vertebral body had fixed atlantoaxial anterior dislocation. Another 3 cases with atlantoaxial lateral mass destruction had spontaneous fusion. Eighteen patients had conservative treatment (1 only by immobilization, 13 by radiotherapy, 2 by chemotherapy, and 2 by combined chemotherapy and radiotherapy) and 12 underwent operation. All the initial symptoms were resolved, and there was no recurrence. From retrospective view, the surgical procedure might be avoided in 60% cases. Twenty-five cases had an average 61.6-month follow-up. In cases with severe bony collapse, the vertebral height ratio increased from 20.0% to 44.9% and the lateral mass height ratio from 22.2% to 56.8%. CONCLUSION Cervical LCH lesions often extend to paravertebral soft tissue, epidural space, pedicles, and even to the endplate and lamina. Needle biopsy under CT guidance is safe and effective. The prognosis of cervical LCH is generally fair. Conservative treatment is usually enough and surgery should be reserved for major neurologic defects like myelopathy or monoparesis.

Abstract
While back pain presents less frequently in children than in adults, it still poses a significant clinical challenge with respect to making a firm diagnosis and developing an effective treatment plan. When children have back pain and medical attention is sought, an underlying pathology is usually suspected. Pediatric patients are evaluated, first, with a complete clinical history and examination and, second, by an imaging work-up that is based on initial findings, including the child's age and size, signs and symptoms, and suspected etiology. This article describes 1) the epidemiology of back pain in children, 2) the imaging work-up used, and 3) the correlation of imaging findings with disease entities that may cause back pain in the pediatric patient. The list of diseases giving rise to back pain is not meant to be exhaustive but rather reflective of the most commonly identified pathologies and disorders among young children and adolescents, from athletic injuries to lethal cancers.

Abstract
OBJECTIVES The goal of this study was to review a large series of patients with Langerhans cell histiocytosis (LCH) who had craniospinal lesions to assess the long-term course, outcome, and efficacy of treatment of the disease. METHODS Forty-four patients with LCH who presented to a single pediatric neurosurgical department between 1976 and 2006 were retrospectively reviewed. RESULTS This series included 29 boys and 15 girls, ranging in age from 2 months to 13 years, with a mean follow-up duration of 4.5 years. Twenty-seven patients (61%) had unifocal bone lesions, 12 (27%) had multifocal bone disease, 2 (5%) had solitary hypothalamic-pituitary axis lesions, and 3 (7%) had multiple organ involvement at presentation. Five (19%) of the 27 patients with unifocal bone disease and 4 (33%) of the 12 patients with multifocal bone disease had delayed development of new bone lesions during the follow-up period. The time to development of new bone lesions ranged from 1 month to 1 year. Two of the 3 patients with multiple-organ LCH died. Patient age < or = 2 years at the time of initial presentation was a risk factor for both initial multifocality and eventual dissemination. In all patients with initial multifocal bone involvement or later dissemination of unifocal bone disease, LCH was controlled by chemotherapy, except for 2 who were treated by surgery alone. Three patients had histological evidence of spontaneous resolution of their lesions. CONCLUSIONS Patients with unifocal LCH can be effectively treated with surgery alone. Very young patients are more likely to have multifocal disease and disseminations, and will usually require chemotherapy to control their disease. Spontaneously regressing lesions need not be resected; however, a biopsy procedure can be performed for diagnostic purposes.

Abstract
We report on a 5-year 8-month-old boy suffering from spinal Langerhans cell histiocytosis (LCH), who had initial symptoms of back and abdominal pain, as well as tilting of the shoulder that mimicked hemivertebra of T10 with scoliosis, as revealed by radiography. The LCH-involved vertebra did not demonstrate the classic radiographic picture of vertebra plana until the vertebral body symmetrically collapsed about 6 months later, when the patient's scoliosis disappeared. The delayed diagnosis of LCH was confirmed by biopsy after another 6 months. Polyostotic lesions affecting C6, T5, T9-12, and L2 were found. This case represented an unusual presentation of LCH as an early disease entity, which resulted in a misdiagnosis of painful scoliosis. We believe we are the first to report LCH as a differential diagnosis of painful scoliosis.

Abstract
Langerhans cell histiocytosis (LCH) is a complex disease entity comprised of three distinct clinical syndromes that demonstrate indistinguishable histology. These syndromes are: eosinophilic granuloma, which is predominantly osseous or pulmonary; Hand-Schûller-Christian's disease, which involves multiple organ systems and, most typically, the skull base; and Letterer-Siwe's disease, the most severe disease manifestation, which typically involves the abdominal viscera. This article reviews our current understanding of Langerhans cell histiocytosis by discussing the history, histology, etiology, and treatment of the disease. It focuses on the radiographic findings and imaging modalities that are the most useful in disease diagnosis and management.

Abstract
CASE REPORT An 11-month-old boy presented with a 3-month history of lower extremity weakness. CT and MRI of the spine revealed an enhancing epidural mass, extending from T1 through T5 and exiting through multiple foramina. The largest extraspinal extent was located at the T3 vertebral level and was accompanied by complete T3 vertebral collapse. A second lytic lesion at the L2 vertebral body without an obvious enhancing mass was also noted. Open biopsy and decompression of the spinal cord were performed, and histopathological analysis revealed a mixed inflammatory lesion with abundant S-100 and CD1a immunoreactive Langerhans cells consistent with the diagnosis of Langerhans cell histiocytosis (LCH). DISCUSSION The authors present a very rare pediatric case of spinal LCH causing spinal cord compression. Possible clues to early detection, consideration of differential diagnoses, and a brief literature review are presented.
