Background:Spontaneous spinal subdural hematoma (SSDH) is a rare condition and causes of acute spinal cord compression, with symptoms varying from mild to severe neurological deficit. SSDH could occur as a consequence of posttraumatic, iatrogenic, or spontaneous causes, including underlying arteriovenous malformations, tumors, or coagulation disorder. Due to its rarity, it is difficult to establish standardized treatment. We present a rare case of SSDH in COVID-19 patient and course of treatment in COVID hospital.Case Description:A 71-year-old female patient was admitted due to instability, weakness of the left leg, and intensive pain in the upper part of thoracic spine as well as mild respiratory symptoms of COVID-19. She was not on pronounced anticoagulant therapy and her coagulogram at admission was within normal range. MRI revealed acute subdural hematoma at the level C VII to Th III compressing the spinal cord. The patient underwent a decompressive Th I and Th II laminectomy and hematoma evacuation. Post-operative MRI revealed a satisfactory decompression and re-expansion of the spinal cord. COVID-19 symptoms remained mild.Conclusion:SSDH represents a neurological emergency, possibly leading to significant deficit and requires urgent recognition and treatment. One of the main difficulties when diagnosing is to consider such condition when there is no history of anticoagulant treatment or previous trauma. Since high incidence of coagulation abnormalities and thromboembolic events was described COVID-19 patients, when considering the pathology of the central nervous system, the bleeding within it due to COVID-19 should be taken into account, in both brain and spine.

The basal ganglia and thalami are paired deep grey matter structures with extensive metabolic activity that renders them susceptible to injury by various diseases. Most pathological processes lead to bilateral lesions, which may be symmetric or asymmetric, frequently showing characteristic patterns on imaging studies. In this comprehensive pictorial review, the most common and/or typical genetic, acquired metabolic/toxic, infectious, inflammatory, vascular and neoplastic pathologies affecting the central grey matter are subdivided according to the preferential location of the lesions: in the basal ganglia, in the thalami or both. The characteristic imaging findings are described with emphasis on the differential diagnosis and clinical context.

This book presents unusual neuroradiology cases, documented with medical history, CT and MRI images, clinical features and radiological findings

Language impairment is frequently observed in patients with Alzheimer’s disease (AD): in this study, we investigated the extent and distribution of brain atrophy in subjects with conversion from mild cognitive impairment (MCI) to AD with and without naming difficulties.

The papillary carcinoma of the thyroid gland is the most common type of tumor of the thyroid gland with good prognosis and low incidence of distant metastasis. The brain metastases of thyroid gland carcinoma are extremely rare. We report a patient with multiple cystic brain lesions and satisfying criteria for diagnosis of neurocysticercosis. Brain biopsy revealed brain metastases from papillary thyroid carcinoma. The tumor originated from mediastinal thyroid tissue. Even in cases when neuroimaging suggests neurocysticercosis with great accuracy, it is important to exclude metastasis. Extensive brain metastases of primary papillary thyroid carcinoma are extremely rare.

Spontaneous intracranial hypotension is a rare condition caused by spontaneous cerebrospinal fluid leak and volume depletion. It is initially misdiagnosed as a cause of an orthostatic headache, which is the most important symptom of the syndrome. It can be presented as one of four types: classic form, normal pressure form, normal pachymeninges form and acephalgic form. The diagnosis is made based on the clinical presentation, physical examination, typical cerebrospinal fluid and magnetic resonance imaging findings. We present a case of a 29-year-old woman with uncommon normal pressure form of the spontaneous intracranial hypotension, characterized by normal cerebrospinal fluid opening pressure, and typical clinical and magnetic resonance imaging findings, including the finding of pituitary gland enlargement with asymptomatic pituitary haemorrhage as an unusual complication.
