Clinical and Imaging Features of Head and Neck Metastasis of High-Grade Glioma: A Single Center Case Series.

High-grade gliomas are the most frequent primary brain tumors, yet extraneural metastasis is exceedingly rare. This is in part secondary to the relatively poor survival of these patients and likely the shielding effect of the blood-brain barrier. Given the rarity of extraneural metastasis, the pathophysiology and imaging appearance of extraneural metastasis is under-reported and poorly understood.

Medulloblastoma, an embryonal tumor located in the posterior fossa of the brain, originates from the neuro-epidermal layer of the cerebellum. It is the most prevalent malignant tumor in children, while it is rare in adults and predominantly affects males. Multimodal therapeutic interventions, such as surgery, radiotherapy, and chemotherapy, have substantially enhanced the prognosis of this condition.

Key Clinical Message: Ependymomas are primary brain tumors that predominantly affect individuals between 0 and 4 years of age. Although ependymomas have a propensity for recurrence and the potential to spread within the central nervous system through cerebrospinal fluid (resulting in drop metastases), reports of extra-neural metastatic localizations are exceedingly rare in the existing literature. This case report presents a unique and rare instance of recurrent intracranial anaplastic ependymoma with a late-onset giant scalp metastasis.

Department of Radiology, Princess Alexandra Hospital, Brisbane, Queensland, Australia.
Introduction: Perineural spread (PNS) is a rare but potentially fatal consequence of cutaneous squamous cell carcinoma (cSCC) of the head and neck. We aimed to evaluate the accuracy of 3T MR neurography in detecting and defining the extent of facial nerve (VII) PNS from cSCC, and highlight characteristic radiological features in peripheral branches to improve early diagnosis.
Methods: Single-institution retrospective review of 38 patients with clinical, radiological, and/or histopathological findings consistent with VII PNS from cSCC who underwent pre-operative 3T MR neurography.
Subacute Brachial Plexopathy due to Intraneural Epithelioid Hemangioma: A Case Report.

October 2023
Department of Neurology, Harvard Medical School, Massachusetts General Hospital, Boston, MA, USA.
Brachial plexopathy is a common consideration in the differential diagnosis of upper extremity sensory and motor deficits, and neoplasms signify one possible etiology of brachial plexopathy. Of the neoplastic brachial plexopathies, hemangiomas involving the brachial plexus are rare. Most reported cases describe extraneural brachial plexus hemangiomas that present as a palpable, tender neck mass associated with pain and sensory disturbance, with minimal motor deficits.
