Cranial neuropathy

Pierre R Bourque, Gabrielle Bourque, William Miller, John Woulfe, Jodi Warman Chardon
Perineural invasion is a targeted cellular proliferation guided by neurotrophins, rather than a simple diffusion of tumor in a path of least resistance. Invasion of cranial nerves by squamous cell carcinoma can represent an important diagnostic dilemma. It commonly presents as a distinct clinical neurological syndrome of combined isolated trigeminal and facial neuropathies. The focal cancer source may have been overlooked or remain occult. This case series illustrates diverse clinical presentations and neuroimaging challenges in four patients with squamous cell carcinoma of the cranial nerves...

Neurotropic melanoma (NM) is a rare variant of cutaneous melanomas. Compared with conventional melanoma, NM is more locally aggressive with an increased tendency for local recurrence but less likely for nodal or distant metastases. The often amelanotic, benign appearance may lead to treatment issues such as late presentation, diagnostic delay, misdiagnosis, insufficient surgical margins, and recurrence with resulting poor outcome. To our knowledge, this is the first case report of NM with contiguous spread to the spinal cord...

IgG4-related disease (IgG4-RD) is increasingly being recognized as an entity effecting the head and neck region. Although most commonly seen with salivary gland or paranasal sinus involvement, IgG4-RD may also involve the temporal bone and skull base. We report a rare care of a 61-year-old female with IgG4-RD presenting as synchronous lesions of the middle ear and middle cranial fossa with polyneuropathy of cranial nerves II, VI, and VII. Initial histopathological evaluation of her resected ear mass suggested a benign inflammatory process but no specific diagnosis...

Several studies have reported the efficacy and safety of hypofractionated stereotactic radiosurgery (hSRS) in the treatment of benign perioptic tumors. This study went further and evaluated the feasibility of hSRS in the treatment of those causing compressive cranial neuropathies (CCNs) among perioptic tumors with special consideration of functional improvement. Twenty-six patients with CCNs (CN II = 19; CN III/IV/VI = 9; CN V = 3) caused by perioptic tumors underwent hSRS between 2011 and 2015...

BACKGROUND: Guillain-Barré syndrome is an acquired polyradiculo-neuropathy, often preceded by an antecedent event. It is a monophasic disease but a recurrence rate of 1-6 % is documented in a subset group of patients. Patients with Guillain-Barré syndrome show cerebrospinal fluid albuminocytologic dissociation. Normal cerebrospinal fluid protein levels during both initial and recurrent episodes of Guillain-Barré syndrome is a rare occurrence and has not been described earlier in the literature...

BACKGROUND: With the introduction of Onyx, transarterial embolization has become the most common endovascular approach to treating dural arteriovenous fistulas (dAVFs), often via the middle meningeal or occipital arteries. The ascending pharyngeal artery (APA) is a less frequently explored transarterial route because of its small caliber, potential anastomoses to the internal carotid and vertebral arteries, and vital supply to lower cranial nerves. OBJECTIVE: To review our institutional experience and highlight the prevalence of APA supply to dAVFs and cases where it is a safe and effective pedicle for embolization...

BACKGROUND: Treatment for Acute Lymphoblastic Leukemia (ALL) can impact balance through different mechanisms, including sensory and motor peripheral neuropathy, cognitive impairment, and reduced muscle strength and flexibility. To provide an overview of what is currently known about the effects of cancer treatment on balance in pediatric ALL patients and survivors and predictors of poor balance a review of literature was conducted. METHODS: Five databases were searched for English language original research articles which have measured balance during or after treatment for pediatric ALL...

BACKGROUND: Neurosarcoidosis occurs in fewer than 5% of adults with systemic sarcoid. However, only 53 examples of neurosarcoidosis have been reported in the pediatric population, with nine of those cases being isolated neurosarcoidosis. We present the tenth case of a child with an initial presentation of isolated neurosarcoidosis and a review of the literature. METHODS: We searched the Ovid Medline database from 1946 to May 28, 2015. The Mesh terms "neurosarcoidosis," "pediatric," and "child" were exploded, and the Boolean "AND" was used to combine "neurosarcoidosis" with "pediatric" or "child...

Syphilis has long been known as the great imitator. Its heterogeneity can manifest in the form of meningitis, space occupying gummas, vasculitis, strokes, cranial neuropathies, myelopathy, dementia, and seizures. The incidence has been rising with each year, mainly in men who have sex with men accounting for 83% of cases. With the coexistence of immunocompromised states, especially HIV (human immunodeficiency virus), the usually chronic and insidious course of tertiary neurosyphilis can be accelerated. Stroke can occur as a result of neurosyphilis in its meningovascular form, and the likelihood of this increases with HIV co-infection, especially in high-risk groups such as intravenous drug users and men who have sex with men...

Today, Lyme disease is the most commonly reported tick-borne disease in the United States and Europe. The culprits behind Lyme disease are the Borrelia species of bacteria. In the USA, Borrelia burgdorferi causes the majority of cases, while in Europe and Asia Borrelia afzelii and Borrelia garinii carry the greatest burden of disease. The clinical manifestations of Lyme disease have been identified as early localized, early disseminated, and late chronic. The neurological effects of Lyme disease include both peripheral and central nervous systems involvement, including focal nerve abnormalities, cranial neuropathies, painful radiculoneuritis, meningitis, and/or toxic metabolic encephalopathy, known as Lyme encephalopathy...
