Introduction Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the fungus Paracoccidioides brasiliensis, and it can compromise the central nervous system (CNS) in 10–27% of all cases. Case Report A 31-year-old man presented to the Emergency Department with headache, left-sided weakness, clonus at the ankle and a positive Babinski sign. Head computed tomography (CT) and magnetic resonance imaging (MRI) scans showed a 5.1 × 3.8 cm lobulated lesion with areas of liquefaction in the right centrum semiovale. Discussion Central nervous system PCM can mimic a brain tumor, and most cases are diagnosed by biopsy of the lesion. The treatment includes antibiotics, but some cases require surgery. Conclusion Due to high morbimortality rates, the diagnosis must be considered, and early treatment started in patients who live in rural regions endemic for PCM when a ring-enhancing mass associated with perilesional edema is observed on MRI scans.

Introduction: Neurocysticercosis is a parasitic disease caused by the cysticerci of Taenia solium. Central nervous system involvement is endemic in underdeveloped countries and intracranial involvement is the most common presentation. Isolated spinal cord involvement is quite rare and definitive diagnosis in most cases is obtained by anatomopathological evaluation. Case Report: 58 year-old female, from Nicaragua, with a 3-year history of dysesthesia and allodynia on right T5 dermatome, with thoracic spine magnetic resonance imaging (MRI) revealing an intramedullary cystic lesion at the level of T4 and T5 vertebrae with perilesional edema. MRI of the rest of the central nervous system was unremarkable. After initial empirical treatment with intravenous methylprednisolone without clinical or radiological improvement, surgical exploration was proposed, confirming the diagnosis of neurocysticercosis. Conclusion: Diagnosing spinal cysticercosis represents a challenge and should to be considered in patients with intramedullary cystic lesions in endemic areas.

The Brain

Magnetic Oxygen-Loaded Nanobubbles (MOLNBs), manufactured by adding Superparamagnetic Iron Oxide Nanoparticles (SPIONs) on the surface of polymeric nanobubbles, are investigated as theranostic carriers for delivering oxygen and chemotherapy to brain tumors. Physicochemical and cyto-toxicological properties and in vitro internalization by human brain microvascular endothelial cells as well as the motion of MOLNBs in a static magnetic field were investigated. MOLNBs are safe oxygen-loaded vectors able to overcome the brain membranes and drivable through the Central Nervous System (CNS) to deliver their cargoes to specific sites of interest. In addition, MOLNBs are monitorable either via Magnetic Resonance Imaging (MRI) or Ultrasound (US) sonography. MOLNBs can find application in targeting brain tumors since they can enhance conventional radiotherapy and deliver chemotherapy being driven by ad hoc tailored magnetic fields under MRI and/or US monitoring.

Solitary fibrous tumor is a very rare mesenchymal tumor that occurs mostly in the pleura, and there are few reported cases of a presence in the central nervous system, particularly in the cerebellum. In 2016, the WHO classified solitary fibrous tumors into grade I. In this article, we present a case of malignant solitary fibrous tumor recurring 8 years after surgery in a 63-year-old male. Magnetic resonance imaging showed low to intermediate mixed signal intensity on T1W1. Immunohistochemical staining positivity for Vimentin, CD99, CD34 and Bcl-2, it is consistent with the immunohistochemical characteristics of solitary fibrous tumor. We resected the patient’s tumor, and the patient was followed up for 3 months with no signs of recurrence. Solitary fibrous tumors are very rare in the central nervous system. Immunohistochemical staining positivity for CD34 and Bcl-2 is strongly expressed in most solitary fibrous tumor. Surgical resection is the preferred treatment. Due to the small number of cases, the biological behavior and prognosis of this tumor need to be further explored.

Intermittent Bleeding

ABSTRACT Superficial siderosis (SS) of the central nervous system (CNS) is a rare and possibly underdiagnosed disorder resulting from chronic or intermittent bleeding into the subarachnoid space, leading to deposition of blood products in the subpial layers of the meninges. Magnetic resonance imaging (MRI) shows a characteristic curvilinear pattern of hypointensity on its blood-sensitive sequences. Methods Series of cases collected from Brazilian centers. Results We studied 13 cases of patients presenting with progressive histories of neurological dysfunction caused by SS-CNS. The most frequent clinical findings in these patients were progressive gait ataxia, hearing loss, hyperreflexia and cognitive dysfunction. The diagnoses of SS-CNS were made seven months to 30 years after the disease onset. Conclusion SS-CNS is a rare disease that may remain undiagnosed for long periods. Awareness of this condition is essential for the clinician.

Paragangliomas are usually benign tumors which can be found in many sites of the body, from the base of the skull down to the pelvic floor. In the central nervous system the sellar region is very rarely involved; only three well studied cases have been reported to date. We present the cytological, histological, histochemical, immunocytochemical and ultrastructural features of an intrasellar and suprasellar paraganglioma in an 84-year-old man.

Parasagittal Meningioma

Most clinicians consider a peripheral nerve lesion in patients with drop foot. However, causes stemming from the central nervous system represent rare, important, and underappreciated differential etiologies. Central causative lesions usually occur at locations where pyramidal tract connections are condensed and specific and the function is somatotopically organized. Here we report case presenting as central foot drop or spastic foot-drop and other myriad clinical features which after investigations was found due to bilateral parasagittal meningiomas.
