RESUMEN
Spinal epidural hematoma (SEH) is a rare condition leading to spinal cord compression after trauma, surgery, or other. In 40% of the cases, the cause is unknown or unidentified. Due to the absence of specific symptoms, the diagnosis is often delayed. The mainstay of treatment is urgent evacuation of the hematoma. The choice of the surgical technique is surgeon-dependent and ranges from simple decompression and hematoma evacuation to variable combinations of decompression and reconstruction of the posterior spinal arch. To our knowledge, we describe the youngest case in the literature of a thoracolumbar SEH in a newborn with hemophilia A which was evacuated by spinous process splitting laminoplasty (SPSL). SPSL was chosen to avoid damaging the primary ossification centers, preserve the paravertebral musculature, and evade the sequelae of multilevel laminectomies. In our opinion, this technique should be propagated in the pediatric population for accessing the posterior and posterolateral spinal canal.

BACKGROUND: Extra-axial cavernoma (EAC) at the cerebellopontine angle (CPA) is a rare clinical entity that can mimic radiologically several lesions encountered at this location. We report a case of EAC-CPA and present a review of the literature. METHODS: A PubMed research was conducted looking for EAC-CPA lesions described in literature. After reviewing all the relevant articles, the following data were extracted and organized into a single table: patients' symptoms, radiological characteristics, surgical procedure, histopathology, and outcome. RESULTS: Eighteen cases (including ours) were identified from these reports. Mean age at diagnosis was 42 with a male:female ratio of 2.6:1. The most commonly involved cranial nerves were the vestibulocochlear complex followed by the trigeminal nerve. The lesions were iso-to hypodense on computed tomography. On magnetic resonance imaging, the EAC-CPA can be solid or cystic. All lesions were approached using retrosigmoid craniotomies. Histologically, both intra- and extra-axial cavernomas are identical, consisting of devoid vascular sinusoids with endothelial lining. The outcome was favorable in 16/18 of the described cases. One case presented a worsened facial paresis and 1 patient died from excessive intraoperative bleeding and subsequent complications. CONCLUSIONS: Despite the fact that EAC-CPA are rarely encountered, it should be kept in mind in the list of differential diagnosis, preparing both the surgeon and anesthesiologist for the surgery of a vascular lesion. Specific radiological features, especially an associated developmental venous anomaly could point to the diagnosis.

Ossification of ligamentum flavum (OLF) is a well-known pathology causing myelopathy, although it is a rare disease. The most commonly affected population is from the Far East and mainly Japanese. However, few reports and studies have shown the prevalence of the disease all over the world. We report the case of a 33-year-old man presenting with signs of progressive myelopathy. Magnetic resonance imaging (MRI) showed Th2-Th11 OLF with severe narrowing and intramedullary hypersignal at the level Th2-Th3. This is the first Lebanese case reported in the literature. A decompressive laminectomy with flavectomy was done. This case adds to the previous reported cases on the occurrence of the disease in different populations.
RESUMEN
Pancreatic injury can occur following high-energy blunt trauma to the torso. Although several types of pancreatic fistulas have been described in literature, we report to our knowledge, the first case of a pancreatico-dural fistula of traumatic origin. A 20-year-old male sustained a severe blow to the thoraco-abdominal region in the setting of a motorcycle accident. A total body scan revealed an AAST (American Association for the Surgery of Trauma) grade 4 splenic injury. A laparotomy with splenectomy and abdominal packing was performed. This was later followed by thoracolumbar instrumentation for posterior fixation of a T11-T12 transdiscal type C fracture with anterior subluxation of T11, according to the AO classification. Subsequent management was complicated by the persistence of a pseudomeningocele despite multiple surgical drainage procedures and a concomitant increase in retroperitoneal fluid collections. High levels of amylase and lipase in the pseudomeningocele fluid confirmed the presence of a pancreatico-dural fistula, due to a Wirsung duct rupture. This case report illiustrates the challenges in the management of this rare condition.
