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. Differential diagnosis and management strategies, as well as follow-up implications are discussed along with literature review, which pointed out that only five cases with no further signs of hematological disorders at follow up have been described in the literature so far and this case has the longest follow up of them at 9 years.

Holocordic Spinal Sbdural Hematoma: A Challenging Management In Emergency: Literature Review.

OBJECTIVE: Spinal subdural hematoma (SSH) is a rare entity and the etiology has yet to be elucidated. Holocordic spinal hematomas represent an exception. The management of these patients remains controversial, due to their rarity and their extremely poor prognosis. METHODS: Electronic databases (MEDLINE, Scopus, and PubMed) were analyzed for studies published through April 2021, searching holocordic spinal subdural hematoma. Case reports, case series, and literature reviews were included. RESULTS: We found only 7 cases describing holocordic SSH reported in the literature, and we added the description of 1 case we managed at our institution, reaching a total of 8 cases. We discuss clinical and radiologic features, etiologic hypothesis, treatment strategies, and prognostic factors. CONCLUSIONS: The correct treatment of holocordic hematomas is not yet well standardized. Complete evacuation is not amenable, but surgical evacuation based on magnetic resonance imaging has shown to be the most effective therapeutic option, crucial in terms of prognosis, even if performed with some delay.

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. The dorsal symptomatic lesion was treated with resection, radiotherapy, and adjuvant chemotherapy. The implications of spinal metastases for the clinical prognosis of this disease are discussed, with a review of the few reported cases of spinal ENB metastases in the literature. CONCLUSIONS: Through the presentation of this case we hope to further contribute to a better understanding of this rare disease's prognosis.
