1/118. Vertebra plana of the lumbar spine caused by an aneurysmal bone cyst: a case report.The patient was a 15-year-old girl who had a lesion of the fourth lumbar vertebra. Plain radiographs suggested vertebra plana, with complete collapse of the body of the fourth lumbar vertebra and no involvement of the intervertebral disk spaces. The presumptive diagnosis was eosinophilic granuloma. Progressive neurologic symptoms required surgical excision of the lesion, decompression, and fusion. Histopathologic examination of the operative specimen confirmed the diagnosis of an aneurysmal bone cyst.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
2/118. adult onset of multifocal eosinophilic granuloma of bone: a long-term follow-up with evaluation of various treatment options and spontaneous healing.We report a case of multifocal-monosystemic Langerhans cell histiocytosis (LCH), formerly usually referred to as eosinophilic granuloma (EG) of bone. The condition developed in a 36-year-old man. A notable infrequent thoracic spine location and two successive distinct costal lesions were observed. Both the first costal site and the vertebral location healed spontaneously; the second costal lesion underwent biopsy resection. The patient's disease course with an 8-year follow-up is discussed with reference to various treatment options, emphasising in selected cases a watchful conservative approach, in view of the widely documented potential for spontaneous healing.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
3/118. A case of bilateral eosinophilic granuloma in the temporal bone.We present a case of bilateral eosinophilic granuloma in the temporal bone in a 47-year-old woman, who visited our hospital with a headache and a feeling of occlusion in her left ear. Her left tympanic membrane was slightly turbid and pure tone audiometry revealed mild left sensorineural deafness. CT disclosed a shadow of soft tissue in the left mastoid antrum and mastoid cells, which was indicative of marked destruction of the bone. Because MRI findings led us to suspect otitis media cholesteatoma, a mastoidectomy was performed. The mastoid antrum and mastoid cells were filled with easily bleeding granulation, and there was a wide range of bone deficit in the posterior cranial fossa. Histopathologically, the granulation tissue was an eosinophilic granuloma. Her postoperative clinical progress was good and she was discharged. However 2 months after discharge, she had a feeling of occlusion in the right ear and CT revealed a shadow in the right mastoid antrum and cells. Therefore, right tympanoplasty was performed and the same findings as in the left ear were obtained. A histopathological diagnosis of eosinophilic granuloma was made again. To date, there has been no recurrence.- - - - - - - - - - ranking = 1.4keywords = bone (Clic here for more details about this article) |
4/118. Cervical spine cord compression by eosinophilic granuloma. Case report.eosinophilic granuloma is a term reserved for the most often and benign form of disorder known as langerhans cells histiocytosis. It is a disease of children and adolescents that very rarely affects adults, representing the localized form of a pathological proliferation of histiocytes in bones, like skull and long bones. Vertebral involvement is uncommon, approximately 8% of the cases, being the cervical localization the least affected. Moreover, the involvement of the spinal cord and roots remains a rare occurrence. Only five cases characterized by signs of cervical spinal cord compression have been reported. We report the sixth case in a 42-year-old-man who evolved with resolution of symptoms, and has remained asymptomatic after treatment. The clinical, radiological and histological features and, also, the value, in selected cases, of surgical treatment followed by low-dose radiation therapy is discussed. A review of the pertinent literature is also presented.- - - - - - - - - - ranking = 0.4keywords = bone (Clic here for more details about this article) |
5/118. Imaging of calvarial eosinophil granuloma.We reviewed the imaging of four pathologically proven calvarial eosinophil granulomas. The diameter of the lesions ranged from 13 to 40 mm; three were biconvex, but the other had a collar-stud appearance. Two lesions were in the frontal and two in the parietal bone. On bone-window CT, a bevelled edge was seen in three cases and button sequestration in one, but no sclerotic rim was shown. Although one lesion had a low-density area, the lesions were slightly denser than grey matter. They were isointense with grey or white matter on T1-weighted MRI and gave heterogeneous high signal on proton-density and T2-weighted images. All enhanced markedly, with a less strongly enhancing portion within them. A tail of dural enhancement and reactive change in the overlying galea or temporal muscle were seen in all cases.- - - - - - - - - - ranking = 0.4keywords = bone (Clic here for more details about this article) |
6/118. Two cases of pediatric bone disease (eosinophilic granuloma and Brodie's abscess) showing similar scintigraphic and radiographic findings.Two 9-year-old patients with femoral bone lesions were referred to the authors' institution within a few days of each other. Both showed similar radiographic, magnetic resonance imaging, and scintigraphic findings. The radiographs showed osteolytic lesions in the right femoral diaphyses, and gadolinium-DTPA-enhanced magnetic resonance imaging revealed inhomogeneous enhancement. Tc-99m HMDP showed marked linear accumulation with relatively low central uptake in the right femoral shafts, and TI-201 scintigraphy showed considerable uptake corresponding to the area seen with Tc-99m HMDP. Histologic analysis confirmed eosinophilic granuloma in the first patient and Brodie's abscess in the second. The radiographic and scintigraphic findings in Brodie's abscess may be similar to those in eosinophilic granuloma.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
7/118. eosinophilic granuloma of the temporal bone.histiocytosis X or Langerhans cell histiocytosis (LCH) is a disease that possesses three less distinctive and overlapping states called eosinophilic granuloma (EG), hand-Schuller-Christian (HSC) disease and Letterer-Siwe (LS) disease. EG is the least severe and localized form of all LCHs and possesses the best prognostic result. A high index of suspicion is required to diagnose the EG, especially when an ear disease is refractory to medical treatment. Early detection is important to manage the EG properly and to minimize the complications or sequels of treatment. Definitive diagnosis of histiocytosis is made by histopathological means and immunohistochemical detection of S-100 and CD1 antigens in the tissue samples. And differential diagnosis of the subgroups is made according to the clinical manifestations such as visceral organ or bone involvement. Surgical excision, radiotherapy and chemotherapy, either alone or in combination, are the main treatment options.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
8/118. Langerhans cell histiocytosis.Langerhans cell histiocytosis (LCH) is a rare disorder affecting predominantly children and manifesting as bone pains, bony swellings and lytic lesions. Involvement of vertebrae as presenting manifestation is unusual. Here we have presented three cases of LCH, two of multifocal eosinophilic granuloma (MEG) and one of hand Schuller Christian disease (HSC). One of the patients with MEG; had vertebral involvement as the presenting manifestation.- - - - - - - - - - ranking = 0.2keywords = bone (Clic here for more details about this article) |
9/118. Unusual presentation of mastoid eosinophilic granuloma in a young patient.eosinophilic granuloma is a well-recognized form of Langerhans cell histiocytosis, most commonly involving the skull bones, usually with an excellent prognosis. Recurrent and difficult to recognize osteolytic lesions of the skull are encountered only rarely. A patient with recurrent eosinophilic granuloma of the skull is reported. In spite of appropriate multimodality treatment, there were several recurrences, most recently with involvement of the mastoid process. Imaging studies revealed extensive involvement of surrounding structures with expansion of the tumor into the middle cranial fossa and slight pressure on the antero-medial portion of the temporal lobe of the brain. Despite extensive involvement, the patient had no complaints. Because of the rarity of such silent and unpredictable lesions, a systematic approach with regular CT and MRI follow-up is suggested.- - - - - - - - - - ranking = 0.2keywords = bone (Clic here for more details about this article) |
10/118. Anterior cervical corpectomy and fusion using miniplate and screws in a 7-year-old child with eosinophilic granuloma of the cervical spine.STUDY DESIGN: This is a case report of a 7-year-old child with eosinophilic granuloma in the cervical spine, which underwent anterior cervical corpectomy and fusion by using Miniplate and screws. OBJECTIVES: To describe the use of Miniplate and screws for pediatric cervical anterior fusion. SUMMARY OF BACKGROUND DATA: eosinophilic granuloma is a rare disease causing destructive bony lesions of the cervical spine in children. A complete resection and fusion were considered to be the preferable treatment in our case. However, cervical spinal fusion and instrumentation in children may be technically difficult because of the size of the vertebral body and the iliac bone. In addition, a proper device for an internal fixation in pediatric patients is not yet available. methods: A case of eosinophilic granuloma in pediatric spine was presented. RESULTS: We confirmed successful bony fusion and the restoration of the normal cervical curvature without recurrence of the tumor 2 years after the procedure. CONCLUSIONS: For proper internal fixation and prevention of dislodgement of the grafted bone, we used the Miniplate and screws as internal fixator after intralesional resection of the tumor mass.- - - - - - - - - - ranking = 0.4keywords = bone (Clic here for more details about this article) |
