5-ALA-Induced Fluorescence in Leptomeningeal Dissemination of Spinal Malignant Glioma.

Background: 5-Aminolevulinic acid (5-ALA)-fluorescence-guided resection of malignant glioma is well established in many neuro-oncology departments. In addition, the use of 5-ALA has been reported for cerebral metastases, meningioma, and spinal tumors. We report a case of a patient with a leptomeningeal spread of a K27M-mutated spinal anaplastic astrocytoma (World Health Organization° [WHO] III), which was detected by its faint 5-ALA-induced fluorescence.

The Importance of Surgery as Part of Multimodal Therapy in Rapid Progressive Primary Extraosseous Ewing Sarcoma of the Cervical Intra- and Epidural Space.

Primary extraosseous Ewing sarcomas (EESs) are an extremely rare pathological entity. Less than 32 cases have been reported in the literature. Here we report an uncommon case with very rapid progression in the cervical region with extra- and intradural involvement.

Recurrent spinal metastasis of a sporadic medullary carcinoma of the thyroid after radiation therapy: a case report and review of the literature.

Sporadic Medullary Carcinoma of the Thyroid is a relatively uncommon entity and at the time of diagnosis, most already present loco-regional metastasis. Therapy should be aggressive to reduce recurrence and mortality. Follow-up period should continue lifelong and should also include calcium/pentagastrin infusion test, as well as 6-month interval diagnostic imaging.

Giant cell tumor of the lumbar spine with intraperitoneal growth: case report and review of literature.

Giant cell tumors of the spine are uncommon. Usually they are benign and solitary, but locally very aggressive. Most of them occur at the sacral spine.

Meningioangiomatosis in a patient with progressive focal neurological deficit-case report and review of literature.

Meningioangiomatosis (MA) represents a vascular hamartoma accompanied by meningothelial cell proliferation. It generally becomes symptomatic with difficult to control seizures, though in some patients it may be asymptomatic. We present the case of a 41-year-old male patient with a newly developed central distal monoparesis of the left leg.
