Spinal sagittal malalignment following surgery for primary intramedullary tumours in children.
As prior studies analysed predictive factors for various post-laminectomy spinal deformities in mixed spinal regions, age groups or pathologies, their validity and conclusions were unclear. The objective of this study was to determine predictive factors for worsened cervical or thoracic spinal sagittal alignment following laminectomy or laminotomy for primary intramedullary spinal cord tumours in children. ⋯ Worsened spinal sagittal alignment following laminectomy or laminoplasty and the need for spinal fusion is more common in the thoracic-thoracolumbar region than in the cervical-cervicothoracic region. In the cervical-cervicothoracic region, operation on a greater number of laminae tends to increase the risk of worsened alignment. In the thoracic-thoracolumbar region, laminectomy is associated with worsened alignment, while laminoplasty reduces this risk; also, pre-operative kyphotic deformity tends to increase the risk of worsened alignment post-operatively.

Review Case ReportsSymptomatic spinal intradural arachnoid cysts in the pediatric age group: description of three new cases and review of the literature.
Spinal arachnoid cysts are a relatively uncommon lesion that may be either intra- or extradural, and intradural spinal arachnoid cysts are even less common. These cysts are usually asymptomatic but may produce symptoms by compressing the spinal cord or nerve roots suddenly or progressively. We present three cases in the pediatric age group with spinal intradural arachnoid cysts without a preceding history of trauma. ⋯ Complete surgical excision of the cysts is the best choice of treatment, and wide fenestration and shunting of the cyst to the peritoneum, pleural cavity or right atrium were the modalities of choice. MRI offers a noninvasive and effective means to make the diagnosis of arachnoid cysts easier. Intradural arachnoid cysts may cause progressive myelopathy; however, the postoperative prognosis is good if the operation is performed prior to neurologic deficits.

Case ReportsSurgery for expansion of spinal tuberculoma during antituberculous chemotherapy: a case report.
We report a case of intramedullary spinal tuberculoma in a girl aged 2 years and 6 months. At the age of 18 months, the patient was hospitalized for 2 months with tuberculous meningitis. ⋯ Laminectomy and partial excision were performed, and the paraparesis improved. In addition to antituberculous chemotherapy and dexamethasone, surgical decompression was needed to treat the expansion of the spinal tuberculoma.

Case ReportsIntracranial complications of frontal sinusitis in children: Pott's puffy tumor revisited.
The objective of the present study is to describe the diagnosis and treatment of intracranial complications of frontal sinusitis (Pott's puffy tumor) in a series of pediatric patients at our institution. A rare entity, Pott's puffy tumor has been reported in only 21 pediatric cases in the literature of the antibiotic era. The hospital records and radiographic files at Rainbow Babies and Childrens Hospital, Cleveland, Ohio, USA, over the previous 16 years were retrospectively reviewed in a search for patients with the diagnosis of Pott's puffy tumor, defined as scalp swelling and associated intracranial infection. ⋯ Even severely impaired patients demonstrated full neurologic recovery. Despite the widespread use of antibiotics, neurosurgical complications of sinusitis continue to occur. A high degree of suspicion, along with prompt neurosurgical intervention and the use of appropriate antibiotics, can result in favorable outcomes in even the sickest patients.
