Disseminated nocardiosis has never been described before in a patient with Waldenstrom macroglobulinemia. We report an unusual case of disseminated nocardiosis in a patient with Waldenstrom macroglobulinemia who presented with pulmonary non-caseating granulomas. The patient was successfully treated with trimethoprim-sulfamethoxazole (TMP-SMX) for 1 year.
A rare case of spontaneous spondylodiscitis caused by Klebsiella pneumoniae in a 55-year-old man who presented with thoracolumbar pain is described. Increased erythrocyte sedimentation rate and C-reactive protein level were pertinent laboratory findings. Computed tomography revealed a paravertebral mass and destruction of the 10th and 11th vertebrae. Magnetic resonance imaging (MRI) showed spondylodiscitis in the same area. Culture of a biopsy sample from the mass grew Klebsiella pneumoniae, while histological examination confirmed the inflammation. A combination of ceftazidime, amikacin and ciprofloxacin resulted in disappearance of the pain. Two months later, MRI showed substantial improvement of the lesions.
A new option for the use of a vascularized iliac bone graft, based on the upper (first or second) lumbar vessels, has been developed. As a pedicled graft, this supero-posteriorly-based vascularized iliac bone graft can reach the vertebrae from T8 to the sacrum, and the lower sternum and thoracic cage. In this report, the vascular anatomy of the flap and clinical experience using it for anterior spinal fusion are described.

Infectious and vaso-occlusive vertebral bone and joint destruction in two patients with sickle cell disease (SCD) are featured by H-shaped vertebrae, kyphotic angulation, osteolysis of endplates and collapse of intervertebral discs as shown by X-ray films and magnetic resonance imaging. Staphylococcal serology supported the diagnosis of staphylococcal osteomyelitis/spondylo-discitis in both SCD patients. The difficulties of establishing the causes and treatment of the osteoarthropathy in these particular cases are discussed in the light of the literature.

Brucellosis is a zoonosis of worldwide distribution presenting with a wide clinical spectrum. Brucellosis can involve any organ or system. The axial skeleton is the most common site of involvement with a frequency ranging from 2% to 53%. Multiple-level spinal involvements are rare. This report describes the first case of noncontiguous synchronous multifocal involvement of all cervical, thoracic, and lumbar regions in a patient with brucellar spondylodiscitis.
Magnetic resonance imaging has become a common tool for the diagnosis and management of osteoarticular infections in children. We retrospectively review the MRI findings in 57 children (age range 4 months to 16 years; mean 6.3 years) diagnosed with osteoarticular infection. Thirty-eight cases were osteomyelitis, 4 were septic arthritis, 6 were spondylodiscitis, 7 were soft-tissue infections, 2 were pyomyositis, and 2 were chronic multifocal osteomyelitis. The pathogenesis and classification of osteoarticular infections are briefly discussed. Currently available imaging techniques are reviewed, and advantages and disadvantages are discussed. Magnetic resonance imaging indications and findings are shown. The most adequate magnetic resonance imaging sequences, as well as the usefulness of intravenous contrast material, are stressed.

Streptococcus agalactiae, or group B streptococcus (GBS), has been traditionally considered an infrequent etiologic agent of disease in adults except for urinary tract infection in pregnant women. Attention has recently been drawn to other adult infections caused by GBS such as skin and soft tissue infections, bacteriemias, pneumonia, meningitis, endocarditis, peritonitis, and bone and joint infections. We present two adult patients with GBS spondylodiscitis and review 30 cases of GBS spinal infection previously reported in the literature. This series clearly illustrates that GBS has recently been recognized as an emerging cause of vertebral infections in adults, particularly in those with chronic underlying diseases, although it can also affect immunocompetent patients without debilitating conditions. Although uncommon, GBS should be considered in the differential diagnosis of infective spondylodiscitis in nonpregnant adults, whatever the patient's immunological status.

We describe three cases of Fusobacterium spp. diskitis and review with attention to risk factors, clinical features, diagnosis, treatment and outcome. In most of the reported cases, a ear-nose-throat infection was found. Clinical manifestations were similar to those of classic bacterial vertebral osteomyelitis. Clindamycin is the most appropriate antibiotic. The outcome seems to be very good without relapse with appropriate treatment compared to pyogenic vertebral osteomyelitis.
Epidural abscess associated with candidal spondylodiscitis is rarely seen, particularly when it involves the cervical and thoracic spine. We report two such cases that were successfully managed with early surgical debridement, as well as medical therapy with intravenous amphotericin followed by oral fluconazole. The literature related to candidal spinal infection is reviewed, and a rational approach to the management of this uncommon condition is proposed. A good outcome may generally be expected with early diagnosis as well as appropriate surgical and pharmacological treatment. Oral fluconazole appears to be useful in the management of candida spondylodiscitis complicated by epidural abscess formation. Treatment until a normal ESR is attained is ideal, and this may be as short as 3 months when surgical drainage has been adequately performed.
A 49-year-old woman complaining of thoracic spine pain for 18 months was admitted to the hospital for evaluation. Magnetic resonance imaging of the thoracic spine showed spondylodiscitis of the T8-T9 intervertebral disk. Computed tomography scan-guided fine needle aspiration of the affected area was performed but it did not reveal the cause of the disease. Because of continuing symptoms and lack of diagnosis the patient underwent a vertebrectomy and substitution of the eighth thoracic vertebra with Moss titanium cylinder filled-up with auto-bone grafts. Culture of the extracted bone grew Mycobacterium tuberculosis, which was resistant to isoniazid and rifampin. Persistent and even invasive diagnostic work up is needed for the proper and prompt management of patients with spondylodiscitis.
We report a case of surgically proven tophaceous gout of the lumbar spine at the L5-S1 level that mimicked infectious spondylodiscitis and epidural abscess on magnetic resonance (MR) images in a 65-year-old woman. The spinal tophi were hypointense on T1-weighted images; focally and strongly hyperintense on T2-weighted images; and heterogeneously, marginally enhancing on contrast-enhanced T1-weighted images. The aim of this report is to emphasize the importance of considering this disease entity in the differential diagnosis of an epidural mass in a patient with chronic back pain.
