We describe a man recently diagnosed with multiple myeloma who presented with progressive spastic paraparesis, encephalopathy and multifocal MRI lesions with haemorrhage. Brain histopathology was consistent with acute disseminated encephalomyelitis (ADEM) with no new clinicoradiological findings on follow-up. This case emphasises the growing paraneoplastic spectrum, including non-classical but treatable disorders such as ADEM.

The tumor board or multidisciplinary cancer meeting (MCM) is the foundation of high value multidisciplinary oncology care, coordinating teams of specialists. Little is known on how these meetings are implemented in Neuro-oncology. Benefits of MCMs include coordination, direction for complicated cases, education, and a forum for communication, emerging technology, and clinical trials. This study identifies participation and utilization of neuro-oncology MCMs. A cross-sectional descriptive survey was dispersed through an internet questionnaire...

Paraneoplastic limbic encephalitis (PLE) is a rare disorder infrequently accompanying malignancy, coexisting in ~50% of the cases with small-cell lung cancer (SCLC). The pathomechanism of PLE is considered to be immune-mediated, with production of specific anti-Hu antibodies and activation of T-cells directed against onconeural antigens present on both tumor cells and neurons. We herein report the case of a 50-year-old male patient who, prior to being diagnosed with SCLC, presented with typical symptoms of PLE (seizures, subacute cognitive dysfunction with severe memory impairment, anxiety and hallucinations)...

Paraneoplastic neurological disorders are uncommon presentations of head and neck cancers. We present a case of a 68-year-old male patient who presented with dizziness, nausea and memory problems. MRI of his brain showed bilateral cerebellar leptomeningeal enhancing signal abnormality with cervical lymphadenopathy. CT imaging of his neck raised the suspicion of a tonsillar primary, which was later confirmed on biopsy. His poorly differentiated HPV positive squamous cell carcinoma was treated with chemoradiotherapy...

BACKGROUND: Some so-called "non-classical" paraneoplastic neurological syndromes (PNS), namely optic neuritis and myelitis, clinically overlap with neuromyelitis optica spectrum disorders (NMOSD), and conversely, in cancer-associated NMOSD, a paraneoplastic etiology has been suggested in rare cases. Therefore, we retrospectively investigated the prevalence of onconeural antibodies, which are highly predictive for a paraneoplastic etiology, and the prevalence of malignancies in NMOSD patients...

To investigate structural, metabolic, and functional connectivity changes in visual and oculomotor structures in a patient with paraneoplastic opsoclonus-myoclonus syndrome, serial resting-state functional and structural MRI, and FDG-PET data were collected during the acute stage and later on when the opsoclonus had resolved. In the acute stage, an FDG-PET scan demonstrated a substantially increased metabolism in structures around the deep cerebellar nuclei [e.g., fastigial nucleus (FN)] and a relatively reduced metabolism in the bilateral occipital lobes which normalized over 12 months...

The term rhombencephalitis refers to inflammatory diseases affecting the hindbrain (brainstem and cerebellum). Rhombencephalitis has a wide variety of etiologies, including infections, autoimmune diseases, and paraneoplastic syndromes. Infection with bacteria of the genus Listeria is the most common cause of rhombencephalitis. Primary rhombencephalitis caused by infection with Listeria spp. occurs in healthy young adults. It usually has a biphasic time course with a flu-like syndrome, followed by brainstem dysfunction; 75% of patients have cerebrospinal fluid pleocytosis, and nearly 100% have an abnormal brain magnetic resonance imaging scan...

INTRODUCTION: Opsoclonus-myoclonus syndrome (OMS) may have a toxin induced, parainfectious, or paraneoplastic etiology. Several autoantibodies have been associated with adult-onset OMS, most commonly antineuronal nuclear antibody 2 (Ri), and it is most frequently associated with breast or small cell lung cancer. The nicotinic ganglionic acetylcholine receptor autoantibody (α3-AChR Ab) has not been described in association. CASE REPORT: A 46-year-old woman was evaluated for symptoms of oscillopsia, tremor, gait imbalance, and mild cognitive deficits that began 6 weeks prior...

Morvan's syndrome (MoS) is a rare, complex neurological disorder characterized by neuromyotonia, neuropsychiatric features, dysautonomia and neuropathic pain. The majority of MoS cases have a paraneoplastic aetiology, usually occurring prior to the diagnosis of the underlying tumour and showing improvement following its treatment. The present study reports the case of a 35-year-old Caucasian male patient who was diagnosed with stage IVA thymoma. Thymectomy, lung resection, diaphragmatic pleurectomy and pericardio-phrenectomy were performed 6 months after neoadjuvant chemotherapy...

In cats, lymphoma (lymphosarcoma) is the most common neoplasm affecting the spinal cord and the second most common intracranial tumour. Although lymphoma commonly develops in the spinal cord as a part of a multicentric process, a primary form may occur. Lymphoma can exhibit a wide range of morphological patterns, including intraparenchymal brain mass, lymphomatosis cerebri, intravascular lymphoma, lymphomatous choroiditis and meningitis, extradural, intradural-extramedullary or intramedullary lymphoma in the spinal cord, or neurolymphomatosis in the peripheral nerves...

Introduction. Bilateral vocal cord paralysis (BVCP) is a potential medical emergency. The Otolaryngologist plays a crucial role in the diagnosis and management of BVCP and must consider a broad differential diagnosis. We present a rare case of BVCP secondary to anti-Hu paraneoplastic syndrome. Case Presentation. A 58-year-old female presented to an Otolaryngology clinic with a history of progressive hoarseness and dysphagia. Flexible nasolaryngoscopy demonstrated BVCP. Cross-sectional imaging of the brain and vagus nerves was negative...

The ataxic syndrome associated with Anti-Yo antibody, or Purkinje cell cytoplasmic antibody type 1 (PCA1), is the most common variant of paraneoplastic cerebellar degeneration (PCD). The typical presentation involves the subacute development of pancerebellar deficits with a clinical plateau within 6 months. The vast majority of cases have been reported in women with pelvic or breast tumors. Magnetic resonance imaging of the brain is often normal in the early stages, with cerebellar atrophy seen later. The underlying mechanism is believed to be an immunological reaction to cerebellar degeneration-related protein 2 (CDR2), a protein usually found in the cerebellum that is ectopically produced by tumor cells...
