Seven patients with growing skull fractures treated between 1983 and 1993 are described. These growing fractures constituted 1.6% of all the cases of skull fractures seen during the period (a total of 449 cases). Based on aetiopathogenesis, computed tomography (CT) appearances, operative findings and management strategies required, three main types of growing skull fractures were recognized. In type I (n = 3) a leptomeningeal cyst, in type II (n = 3) damaged and gliotic brain, and in type III (n = 2) a porencephalic cyst extended through the skull defect into the subgaleal space. A combination of type I and type III co-existed in one patient. Initial head injury and neurological deficit were judged to be mild to moderate in all the seven cases. Continued growth of skull fractures correlated closely to the increasing neurological deficit in five cases. In two patients natural arrest of fracture growth at 5 and 7 months after trauma was accompanied by arrest in progress of neurological deficit. Available surgical options are discussed and general guidelines for the management are given.
This paper is an attempt at defining the most efficacious surgical and antifungal therapy for invasive cranial and intracranial aspergillosis, and is based on experience with nine non-immunocompromised patients treated and followed-up by the authors between 1983 and 1994; as well as on the summary of previously reported cases and advances in therapy of this condition. Depending on the degree of aspergillar involvement of the cranial base and intracranial structures, a classification, with implications for treatment and prognosis, is also proposed. Two patients had extracranial skull base erosion; whereas relentlessly progressive granulomas, mimicking malignancy, invaded the skull base and intracranial contents in seven cases. Of these seven patients with cranial and intracranial invasion, two died of acute intracranial haemorrhage due to fungal invasion of cerebral blood vessels. In two patients, complete surgical eradication of the disease proved impossible due to cavernous sinus involvement, while residual aspergillomas are still present in orbit and paranasal sinuses (PNS) in a further two patients in spite of multiple surgical procedures and prolonged antifungal chemotherapy (AFC). What appears to be a cure has been effected in one patient only. Multiple therapeutic strategies were used. Biopsy plus systemic AFC was ineffective, surgical drainage and debridement plus systemic AFC resulted in long-term survivals but no cure. Radical surgery in conjunction with systemic and local (intracavitary) AFC should be considered to improve an otherwise poor prognosis.
Twenty-three patients with atypical forms of spinal tuberculosis treated between 1975 and 1985, are described. All presented with signs and symptoms of compression of the spinal cord or cauda equina, ranging from paraesthesiae and increasing weakness of extremities to paraplegia and loss of sphincter control. None of them showed visible or palpable spinal deformity nor the typical radiographic appearance of destruction of the intervertebral disc and the two adjoining vertebral bodies. These atypical forms constituted about 12 percent of all the cases of spinal tuberculosis seen (a total of 190 cases); and fell into three well-defined groups: those with the involvement of neural arch only; those with the involvement of a single vertebral body; and, those without bony involvement. The correct surgical approach in these groups was found to be different: spinal cord compression caused by the tuberculous disease of the neural arch was best treated by laminectomy; whereas single vertebral body disease required an anterior or anterolateral approach. Spinal computerized tomography was helpful in defining the extent of disease and planning the surgical approach. Histological confirmation of tuberculosis was obtained in all the cases and acid fast bacilli (A.F.B.) were found in, and cultured from, the biopsy specimens of 18 cases.
Thirteen patients, aged 7 to 45 years, have been treated for atypical forms of spinal tuberculosis at the Neurological Centres at Benghazi and Lahore. All presented with signs and symptoms of compression of the spinal cord or cauda equina, ranging from paraesthesiae and increasing weakness to paraplegia and loss of sphincter control. None of them showed visible or palpable spinal deformity nor the typical radiographic appearance of destruction of the intervertebral disc and the two adjoining vertebral bodies. These atypical cases fell into two well-defined groups: those with involvement of the neural arch only, with associated intraspinal cold abscesses, and those with involvement of a single vertebral body, resulting in its collapse and a radiographic appearance similar to that in secondary carcinoma of the vertebral body. The correct treatment in these two groups was diametrically opposed. Tuberculous disease of the neural arch was best traced by laminectomy; concertina collapse of a single vertebral body required cost-transversectomy and resection of the transverse process, the pedicle, and the portion of the vertebral body that was encroaching on the spinal canal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
