Dolichoodontoid is defined as hypertrophy of the apical portion of the odontoid process of the axis. We report the first case of a dolichoodontoid process in a pediatric patient with other congenital anomalies. This rare entity has had three previous citations in the literature. Our patient presented with scoliosis in which subsequent MRI demonstrated a Chiari I malformation, a small thoracic syrinx and a dolichoodontoid process. The diagnosis of this malformation should be entertained in cases of craniocervical anomalies.

One girl aged 13 years and 2 boys aged 18 and 14 years had a painful scoliosis. Plain radiographs, blood tests and MRI revealed no abnormalities. Bone scintigraphy and CT scans were needed to establish the diagnosis 'osteoid osteoma'. In the girl, the initial CT scan was also negative and the tumours could only be found after using thin slices. She had had the complaints for 6 months and both boys had had the complaints for more than a year, before the diagnosis was made. They all made a complete recovery after surgical resection. A chronic painful back in young patients is often caused by structural deformities. The differential diagnosis also includes an osteoid osteoma. If an osteoid osteoma is suspected, then after radiographs, bone scintigraphy is indicated, which if necessary can be followed up with targeted CT scans.

Osteoidosteomas are common bone tumours in childhood. Frequently they occur in the long bones of the lower extremities, less frequent in the humeri, phalanxes or the axial skeleton. The tumour is benign and noninfiltrative. Metastases do not occur. Typical complaints are nightly pain attacks, which are relieved by nonsteroidal antiinflammatory drugs. On X-ray, the classic finding is a small radiolucent area surrounded by sclerotic bone in the cortex. Surgical excision is often recommended, providing the possibility for a histological diagnosis. Therapeutic alternatives are percutaneous coagulation of the nidus by alcohol or laser, thermo-coagulation or high-frequency radioablation. Spontaneous remissions are well documented. Therefore the decision to wait and see and to treat with antiinflammatory medication is a considerable therapeutic option. We present two patient with an ostoidosteoma in the proximal femur. One of them underwent an unsuccessful trial for surgical extirpation and histological examination but afterwards developed a severe hip contraction with scoliosis. In the case of the other patient a primary operation was abandoned. Pain was completely controlled upon treatment with nonsteroidal antiinflammatory drugs in both patients. The contractions also disappeared completely upon physiotherapy. Serial MRI showed a significant regression of the inflammatory reaction in one case and the disappearance of the tumour in the other one. In conclusion, pharmacomedical therapy can be recommended, if the diagnosis is doubtlessly and a close follow up is established. The risk of anaesthesia and surgical treatment should be weighted against the risk of nonsteroidal antiinflammatory drug treatment.

The onset of tuberculous spondylitis is insidious in nature, with various clinical presentations, slow development of radiographic abnormalities, and nonspecific constitutional symptoms. This lack of specific symptoms causes delays in diagnosis. Magnetic resonance imaging demonstrates osteitis, intraosseous abscesses, paravertebral and epidural soft tissue extensions and abscesses, discitis, multilevel involvement of spinal cord or nerve root compression, and scoliosis. We present six patients with tuberculous spondylitis referred to our outpatient department with back pain resistant to medical therapy. All of them were women aged from 25 to 58 years (mean 44.6). The diagnosis of tuberculous spondylitis was based on clinical presentation, radiographic and/or MRI evidence of focal destructive vertebral lesions (with paravertebral mass), and positive bacteriological findings of Mycobacterium tuberculosis. The combined antituberculous chemotherapy consisted of 1.0 g/day streptomycin for 1 month, 25 mg/kg ethambutol or 25 mg/kg pyrazinamide, 600 mg/day rifampicin, and 300 mg/day isoniazid. The duration of therapy was 12 months. All the patients recovered without any sequelae. The mean follow-up period was 28 months (range 12-48). Magnetic resonance imaging is considered the main imaging modality for patients with suspected tuberculous spondylitis; it must be included in differential diagnosis of back pain and, if it is diagnosed in early stages, antituberculous chemotherapy enables satisfactory outcome.

A 36-year-old female patient with a long-standing asymptomatic lower thoracic scoliosis presented with sensory symptoms involving all limbs. MRI scan demonstrated a rounded ventral intradural mass causing major deformity of the cervical cord at C6 and C7 levels. Unlike most previously reported neurenteric cysts, the MRI signal characteristics of this mass were such that it could not be determined if it is cystic or solid, being iso-intense on T1- and hyperintense T2-weighted images. Resection was performed through a median corporectomy of C6 and C7, the lesion being found to be a neurenteric cyst with an attachment to the anterior median fissure of the cord. Strut graft and cervical locking plate fixation from C5 to C6 was facilitated by extending the cervical incision into the sternal notch, with detachment of left-sided strap muscle insertion. The patient made an excellent recovery with complete resolution of neurological symptoms and solid fusion. The postoperative course was complicated by an anterior cervical CSF collection which resolved spontaneously within 2 months. The literature regarding this rare condition and its management is reviewed. Although the majority of intraspinal neurenteric cysts are situated ventral to the cord, most reports of excision have been from a dorsal approach. Drainage and subtotal excision of neurenteric cysts have been previously advocated; however, the recurrence rate is such that complete excision is advocated. This is facilitated by a ventral approach. A simplified method of utilising the sternal notch exposure is reported. The literature regarding the anatomical peculiarities pertinent to the sternal notch approach, and the reported literature regarding spinal neurenteric cysts is reviewed.

Correlations between intervertebral disc degeneration and bone mass were investigated previously, but never on scoliotic patients. Using MRI measurements of intervertebral discs behavior and vertebral bone tomodensitometry, correlations between nucleus zone displacement within intervertebral discs and mechanical center migration within vertebral bodies were investigated in vivo on scoliotic patients. The protocol, performed on eleven scoliotic girls, was composed of a CT scan acquisition of apical and adjacent vertebrae followed by a MRI acquisition of the thoracolumbar spine. The displacement between the vertebral body centroid and inertia center was computed from the CT images and called the mechanical migration. The displacement between nucleus zones and vertebral body centroids was quantified from MRI and called the nucleus zone migration. For apical vertebrae, a significant correlation was found in the coronal plane (r = 0.766, p < 0.01), but not in the sagittal plane (r = -0.349, p > 0.05). For adjacent vertebrae, significant correlations were found in both coronal (r = -0.633, p < 0.05) and sagittal (r = -0.797, p < 0.01) planes. The nucleus zone migration occurred in the convexity of the curvature whereas the mechanical migration occurred in the concavity.Known secondary mechanical phenomenon of scoliosis was quantified using new parameters describing intervertebral discs and vertebral bodies. Further investigations should be performed to explain the mechanical evolution of scoliosis and to use these parameters in predictive criteria of scoliosis.

The aetiology of the three-dimensional spinal deformity of idiopathic scoliosis (IS) is unknown. Progressive adolescent idiopathic scoliosis (AIS) that mainly affects girls is generally attributed to relative anterior spinal overgrowth from a mechanical mechanism (torsion) during the adolescent growth spurt. Established biological risk factors to AIS are growth velocity and potential residual spinal growth assessed by maturity indicators. Spine slenderness and ectomorphy in girls are thought to be risk factors for AIS. Claimed biomechanical susceptibilities are (1) a fixed lordotic area and hypokyphosis and (2) concave periapical rib overgrowth. MRI has revealed neuroanatomical abnormalities in approximately 20% of younger children with IS. A neuromuscular cause for AIS is probable but not established. Possible susceptibilities to AIS in tissues relate to muscles, ligaments, discs, skeletal proportions and asymmetries, the latter also affecting soft tissues (e.g. dermatoglyphics). AIS is generally considered to be multi-factorial in origin. The many anomalies detected, particularly left-right asymmetries, have led to spatiotemporal aetiologic concepts involving chronomics and the genome altered by nurture without the necessity for a disease process. Genetic susceptibilities defined in twins are being evaluated in family studies; polymorphisms in the oestrogen receptor gene are associated with curve severity. A neurodevelopmental concept is outlined for the aetiology of progressive AIS. This concept involves lipid peroxidation and, if substantiated, has initial therapeutic potential by dietary anti-oxidants. Growth saltations have not been evaluated in IS.

In 1975, Sharpe and Silversides described a neurological entity in a Chinese family. Clinical picture was characterized by paralysis of horizontal gaze, pendular nystagmus and progressive scoliosis. To date, 43 cases have been reported. The pathogenesis remains unclear. The Authors report four Tunisian families with 12 affected individuals. The age of patients ranges from 6 to 34 Years. All examined patients have complete lateral gaze palsy, pendular nystagmus and progressive scoliosis. Blood routine tests, cerebrospinal fluid (CSF), evoked potentials, electromyography (EMG), muscle biopsy, CT scan and cerebral MRI were normal. Autosomal recessive (AR) mode of inheritance is the most probable pattern.

The management of congenital scoliosis requires a systematic approach with careful attention to detail. Any fortuitous diagnosis of vertebral anomalies in infancy, even if there is no significant scoliosis at that time on x-ray, requires frequent clinical and radiographic follow-up to detect progression. The presence of associated anomalies of the spinal cord, the kidneys and the heart should be evaluated by MRI, renal ultrasound or IVP, with cardiology evaluation as indicated. Curve progression or severe vertebral anomalies known to cause curve progression require immediate treatment to prevent deformity. Significant thoracic deformity, especially in a patient with thoracic insufficiency syndrome, is best treated with expansion thoracoplasty. The patient with congenital scoliosis requires a long term commitment to care with frequent orthopaedic follow-up throughout the growing years along with routine pulmonary function assessment once the patient is able to cooperate with testing.

The coincidence of split cord malformation (SCM) and intraspinal teratoma is an extremely uncommon condition. We report a case of a neurologically asymptomatic 13-year-old girl with a 5-year history of progressive scoliosis. The routinely performed MRI revealed SCM at levels L1-L2, tethering of the spinal cord at levels L4-L5 and the presence of an intraspinal tumour at the level of the observed SCM. Intraoperative investigation revealed composite character of SCM. The hemicords were separated by an osseo-cartilaginous septum and contained in a single dural tube. We claim that this is the second described case of a composite SCM and an intraspinal teratoma coexisting at the same level. This case supports the idea that scoliosis may be accompanied by congenital spinal cord anomalies like SCM and intradural tumours. MRI should be the basic diagnostic investigation in such cases. Scoliosis coexisting with SCM and an intradural tumour requires complex neurosurgical and orthopaedic treatment.
