Clinico-pathological study of intradural extramedullary spinal tumors

Simpson grade 3 resection does not improve clinical outcome in neglected thoracic psammomatous spinal meningioma? A case report

“…Regardless of the extent of dural removal, a prime goal throughout the surgery should be the maintenance of minimal or no retraction of the spinal cord, as this is likely to be associated with favorable immediate postoperative and long-term outcomes as in the present case [11]. The current perspective noted that adjuvant radiation therapy Another standpoint is better to reserve for recurrent, difficult to reach, high-grade cases than after first surgery incorporating the risk of irradiating a functional spinal cord with no proven benefit, especially the lesion that was located in the anterior and difficult to reach without spinal cord radiation exposure [7]. The preferred approach or procedure must be tailored case by case based on preoperative surgical grading of the tumor and its associated factors.…”

“…The definitive diagnosis delay from the onset of symptoms was commonly found in this case. A study by Pesna et al found a median delay in diagnosis of 24 months (range three days to 24 years) amongst 57 patients, referred to them between 1978 and 1988 [7]. The majority of patients often present with pain, sensory-motor deficit, and sphincter disturbances.…”

“…Posterior laminectomies indicated for the mass that located posteriorly. If the tumor located anteriorly, the tumor removal can be counter through extended lateral laminectomy towards the articular process, which gives excellent exposure with minimal displacement of the spinal cord or an anterior approach via posterolateral thoracotomy [7]. With total excision of the tumor, recurrence-free survival rates of 93%, 80%, and 68% at 5, 10, and 15 years can be anticipated [10].…”

Spinal biopsies: a clinicopathologic review of 53 cases diagnosed between 2011 and 2018 at a tertiary hospital in Kampala, Uganda

“…Anatomically, the PSCN have been divided into two main types: extradural and intradural types based on their vicinity to the thecal sac which encloses the spinal cord and cauda equina [12,13]. Extradural PSCN are located outside the thecal sac, and they account for approximately 60% of all PSCN [12].…”

“…Extradural PSCN are located outside the thecal sac, and they account for approximately 60% of all PSCN [12]. The intradural types whose incidence is 30% are further subdivided into two types: extramedullary and intramedullary types [6,13,14]. Approximately 10% of the PSCN are naturally associated with both intradural and extradural components of the spinal cord parenchyma [12].…”
