RESUMO
Background: Spontaneous spinal epidural hematomas (SSEHs) are exceedingly uncommon, especially in infants, with only two reported cases. Diagnosis can be delayed due to the nonspecificity of presenting symptoms. Case Report: We present a case of SSEH in a 10-month-old boy admitted to the pediatric emergency department with a 5-day history of progressive lower extremity motor weakness. There was no history of prior trauma. Magnetic resonance imaging of the spine revealed a posterior epidural hematoma extending from C7 to L4. After hematoma evacuation, the patient's neurological status gradually improved, and no sensorimotor deficit was present 3 weeks postoperatively. Conclusion: Our case suggests that surgical intervention can lead to an excellent prognosis for SSEH in infants, even if the diagnosis is delayed.
RESUMO
Background: Epidermoid cysts (ECs) are rare benign tumors arising from epidermal cells, associated with congenital abnormalities or acquired through trauma, surgery, or lumbar punctures. They represent <1% of all intraspinal tumors and may be associated with limited dorsal myeloschisis (LDM). Case Description: A 7-year-old neurologically intact male had a dorsal skin mass since birth located posteriorly in the midline of the inferior thoracic spine. The mass was palpable, painless, mobile, vascularized, and could be transilluminated. Thoracic magnetic resonance imaging showed an extensive intradural extramedullary cystic lesion extending from D6 to D8 that did not enhance with contrast, accompanied by a subcutaneous fluid collection at D8-D9 communicating with the subarachnoid space. The patient underwent gross total resection of the lesion, pathologically confirmed as an EC. The postoperative course was uneventful, with no recurrence 1 year postoperatively. Conclusion: LDM may be associated with ECs. Early diagnosis and surgical resection of these lesions are essential for favorable outcomes.
RESUMO
Background: Pediatric glioblastoma multiforme (p-GBM) is an exceptionally rare and aggressive brain tumor, with even fewer reported cases with radiographic and intraoperative characteristics that mimic those of extra-axial lesions, often posing a diagnostic challenge. Despite advancements in imaging technologies, the diagnosis of GBM can still be intricate, relying primarily on histopathological confirmation. Case Description: We present a unique case of a 15-year-old female who presented to our hospital with a new-onset focal-to-bilateral tonic-clonic seizure described as clonic movements of her left hemicorps; on clinical examination, a subcutaneous mass was evident in the right parietal region. Magnetic resonance imaging of the brain revealed a sizable extra-axial enhancing mass measuring 9 cm, located in the right parieto-occipital region with notable bone invasion. Moreover, the intraoperative findings revealed an extra-axial mass attached to the dura. Total en bloc resection was achieved. The histopathological analysis confirmed the diagnosis of glioblastoma multiforme. Subsequently, the patient underwent adjuvant radiotherapy in conjunction with temozolomide chemotherapy. Postoperatively, she exhibited clinical improvement and remained stable throughout the 6-month follow-up period. Conclusion: We present the first case of extra-axial p-GBM in a young patient, which remarkably led to the destruction of the bone and finally resulted in a sizable parietal subcutaneous lesion in the absence of prior surgery or radiation.
