Presentation of intracranial meningiomas in Johannesburg (a 12-month prospective study at Charlotte Maxeke Johannesburg Academic Hospital and Chris Hani Baragwanath Hospital)
The study aimed at determining the relative frequency of intracranial meningiomas among primary brain tumours; age, gender, ethnic distributions and their mode of presentation.
This was a 12-month prospective study of 48 consecutive patients with histologically proven intracranial meningiomas seen at CMJAH and CHBH.
Meningiomas accounted for 33.8% of all primary brain tumours. The mean age of patients was 45.7 ± 10.1 years with a female-to-male ratio of 3.8:1. The peak age range at presentation was in the fifth (41.7%) and sixth (27.1%) decades. The highest frequency was in Blacks (75%) and Sotho ethnic nationality (27.1%). The mean duration of symptoms and signs was 24.4 ± 26.5 months. The commonest presentations were headache (87.5%), visual impairment (64.6%), seizures (43.8%), motor deficit (37.5%), convexity meningiomas (25%), meningothelial subtypes (39.6%) and WHO grade I tumours (81.3%).
This study showed that meningiomas are the most common primary intracranial tumours among adults in our environment
Histo-pathological pattern of intracranial tumours in the National Hospital, Abuja
Background/aims: Intracranial tumours demonstrate characteristic diagnostic histopathological features. Our aims were to look at the histo-pathological pattern of intracranial tumours in our environment including their age and sex distribution.Methods: The histology request forms and slides of all intracranial specimens submitted to the histo-pathology department of National Hospital, Abuja, over an 11 year period (2005 and 2015) were retrospectively reviewed.Results: Intracranial specimens and intracranial tumours accounted for 0.6% and 0.5% respectively of all samples submitted. Meningiomas accounted for the most frequent diagnosis for all intracranial specimens and intracranial tumours at 35% and 41% respectively followed by pituitary adenoma at 19% and 22%, and astrocytoma at 13% and 20%. The male female ratio for all diagnoses was 1:1. The mean age at diagnosis was 35 ± 17.1 years. The frequency of intracranial tumours in children was 11.8% with a mean age of 8.3 ± 4.4 years and an equal sex distribution. In children, glioma and embryonal tumours were the most frequent diagnosis at 25%.Conclusion: The histo-pathological pattern of intracranial tumours in our environment showed that meningioma is the most common intracranial tumour in adults, while glioma and embryonal tumours are the most common intracranial tumours in children.Keywords: Histo-pathological pattern, intracranial tumour, meningioma, glioma, embryonal tumours
Management challenges of traumatic spondylolisthesis of the Axis with an unusual C2-C3 posterior subluxation in a paediatric patient: case report and literature review
Introduction: Paediatric cervical spine injuries are uncommon. Traumatic spondylolisthesis of the axis (TSA) is commonly encountered in the trauma setting. The management of TSA may be surgical or non-surgical. Decision making is quite challenging depending on patient presentation and nature of injury, and even more so in the paediatric age group.Objectives: To present a case report highlighting the challenges in the management of TSA.Methods: We present an 8 year old male, who sustained a bilateral C2 pars fracture with associated unusual C2-C3 posterior subluxation.Results: Neuroradiological studies identified the fracture/subluxation of C2-C3 and revealed an intact but posteriorly displaced C2-C3 disc causing cord compression. An Extension Halter traction was initially commenced. This seemed to have worsened the patient’s neck pains, and caused motor weakness and autonomic dysfunction. An anterior cervical discectomy and fusion was finally decided on and performed after evaluation and brainstorming by our spinal Unit. Intra-operative findings revealed separation of the C2-C3 disc from the C3 superior end plate which probably explains the unusual nature of the subluxation.Conclusion: The case shows that surgical intervention as a primary management for TSA even in the paediatric age group is safe and also avoids risks inherent in conservative management.Keywords: Management challenges, traumatic spondylolisthesis of the axis, C2-C3 subluxation, paediatric, anterior cervical discectomy and fusion (ACDF)
Diagnostic challenges and surgical management of co-existent osteoblastoma and aneurysmal bone cyst of the lumbar spine in a child: case report
Background: Osteoblastomas (OTB) with co-existent aneurysmal bone cysts (ABC) of the spine are extremely rare and more so in the lumbar spine. To the authors’ knowledge, only one case of lumbar spine involvement has been reported in a paediatric patient.Objectives: To highlight diagnostic challenges and surgical management of co-existent lumbar OTB-ACB in a child.Methods: We present a 14-year old female with low back pain and progressive swelling of 2 months. She was evaluated by neuroimaging studies and histopathological assessment of resected tissue.Results: X-ray showed a lytic lesion in L3 with loss of the left pedicle. Magnetic resonance imaging (MRI) revealed a fluid-filled, heterogeneously enhanced, lobulated lesion posterior to the vertebral bodies of L3, L4 and L5, which infiltrated the quadratus lumborum muscles bilaterally, and histologically diagnosed as ABC. The L3 pedicle also revealed an expanded, heterogeneously enhanced mass lesion which appeared to be different and showed no fluid-filled levels, histologically diagnosed as OTB. Surgical intervention involved tumour excision with partial spondylectomy of L3 vertebra, posterior instrumented stabilization and fusion.Conclusion: The case highlights the diagnostic challenges of co-existent OTB-ABC and the significant role of surgical management via spinal reconstruction, stabilization and fusion after gross total tumour excision.Keywords: Osteoblastoma, aneurysmal bone cyst, lumbar vertebra, paediatric, instrumented fusion
Management challenges of traumatic spondylolisthesis of the Axis with an unusual C2-C3 posterior subluxation in a paediatric patient: case report and literature review
Introduction: Paediatric cervical spine injuries are uncommon.
Traumatic spondylolisthesis of the axis (TSA) is commonly encountered
in the trauma setting. The management of TSA may be surgical or
non-surgical. Decision making is quite challenging depending on patient
presentation and nature of injury, and even more so in the paediatric
age group. Objectives: To present a case report highlighting the
challenges in the management of TSA. Methods: We present an 8 year old
male, who sustained a bilateral C2 pars fracture with associated
unusual C2-C3 posterior subluxation. Results: Neuroradiological studies
identified the fracture/subluxation of C2-C3 and revealed an intact but
posteriorly displaced C2-C3 disc causing cord compression. An Extension
Halter traction was initially commenced. This seemed to have worsened
the patient\u2019s neck pains, and caused motor weakness and autonomic
dysfunction. An anterior cervical discectomy and fusion was finally
decided on and performed after evaluation and brainstorming by our
spinal Unit. Intra-operative findings revealed separation of the C2-C3
disc from the C3 superior end plate which probably explains the unusual
nature of the subluxation. Conclusion: The case shows that surgical
intervention as a primary management for TSA even in the paediatric age
group is safe and also avoids risks inherent in conservative
management
