Late Intramedullary Spinal Metastases from Esthesioneuroblastoma: Case Report and Prognostic Implications.

Background: Esthesioneuroblastoma (ENB) is an uncommon neuroectodermal tumor that originates from the olfactory mucosa and often recurs locally. Distant metastases of ENB have been described, but there are few reports of intramedullary metastases to the spinal cord.

Case Description: Here we report a case of a patient presenting with a progressive paraparesis and magnetic resonance imaging findings of multiple drop metastases to thoracic and lumbar regions of the spinal cord, 17 years after diagnosis and treatment for an intracranial ENB with subsequent neck nodal metastases.

Isolated intracranial myeloid sarcoma: report of a case and review of the literature.

Myeloid sarcoma is a rare malignant tumor of primitive myeloid cell origin often associated with hematologic disorders. The central nervous system is rarely involved and differentiating between myeloid sarcoma and other tumors is not possible on imaging. Here we present the rare case of an isolated intracranial myeloid sarcoma, initially misdiagnosed radiologically as a meningioma, treated with surgical total resection and subsequent chemotherapy, with no signs of any hematological disorder at follow up.

Isolated Oculomotor Nerve Palsy as Presenting Symptom of Bilateral Chronic Subdural Hematomas: Two Consecutive Case Report and Review of the Literature.

Background: Isolated oculomotor nerve palsy (ONP) is caused most commonly by vascular disease, posterior circulation aneurysms, and inflammatory or traumatic injury. ONP usually occurs in chronic subdural hematoma (CSDH) as a common sign of cerebral herniation that typically is associated with a deterioration of consciousness.

Case Description: We report 2 cases of bilateral CSDH who presented with ONP without deterioration of consciousness.

Multidisciplinary treatment of giant invasive prolactinomas in paediatric age: long-term follow-up in two children.

Background: Invasive giant prolactinomas are rare tumours, still representing a therapeutic challenge due to their characteristics of invasiveness and variable clinical course. Giant prolactinomas in childhood are extremely rare. Only single case reports have been described in the literature.

Cystic craniopharyngioma: trans-sphenoidal surgery and intra-cystic apposition of "bleomycin wax".

Background: The current therapeutic approach to craniopharyngioma is multidisciplinary. Sub-total removal, followed by adjuvant treatments, especially in large cystic tumours, is an accepted regime reported by many authors.

Case Report: A young patient with an intra- and suprasellar cystic craniopharyngioma was operated on via a microsurgical trans-sphenoidal approach, achieving sub-total removal and bleomycin mixed with bone wax ("bleomycin wax") applied to the capsular remnant.

Validity of percutaneous controlled radiofrequency thermocoagulation in the treatment of isolated third division trigeminal neuralgia.

Background: Of 756 percutaneous controlled radiofrequency thermocoagulations of gasserian ganglion and/or retrogasserian rootlets for idiopathic trigeminal neuralgia or for trigeminal neuralgia in multiple sclerosis, the results in 158 patients who had isolated third division trigeminal neuralgia were reviewed.

Methods: In 129 patients, percutaneous thermocoagulation was fluoroscopic guided, whereas in the last 29 the procedure was performed under CT control. In all cases, the goal was to achieve selective anesthesia limited to the third trigeminal division.

Low-grade primary meningeal lymphoma: case report and review of the literature.

Primary meningeal lymphoma is a rare occurrence. We present a case of an immunocompetent patient operated on for a fronto-parietal lesion similar to a meningioma, which the histological examination diagnosed as a mucosa-associated lymphoid tissue (MALT)-type lymphoma. She received no further post-operative treatment and after 36 months showed no evidence of disease.

Spinal epidural abscess complicating chemotherapy in patients with leukemia.

The authors reviewed the basic facts about infections that complicate chemotherapy, and found that a difference exists between those that are medically treated, for which several standard protocols have been adopted, and infections amenable to surgical treatment, such as spinal epidural abscess, which are managed according to the experience at individual institutions. The authors believe that patients with leukemia who manifest a spinal epidural abscess should always be surgically treated when the infection occurs between the induction and remission phases, whereas medical treatment options can be considered for spinal epidural abscesses occurring at the end of the chemotherapy course.
