Tuberculoid Granuloma in the Brainstem: Case Report

AbstractMeningitis or meningoencephalitis are the most common presentations of Koch bacilli infection on the central nervous system (CNS), especially in immunosuppressed patients, in whom the bacilli normally reaches the meninges and the cerebral parenchyma.. A least common pathological presentation is the tumoral growth pattern disease known as tuberculoma. This pathological entity is more common in the cerebral hemispheres and is rarely located in the brainstem. The present case report describes a case of a 55-year-old patient under regular antiretroviral therapy who was hospitalized with signs of brainstem and cerebellar disturbances. Computed tomography (CT) and magnetic resonance imaging (MRI) of the brain showed an exophytic lesion in the dorsal region of the pons. The patient underwent total resection of the lesion and the histopathologic analysis was consistent with a tuberculoma.

AbstractThe Kernohan-Woltman notch phenomenon is a paradoxical neurological manifestation consisting of a motor deficit ipsilateral to a primary brain injury. It has been observed in patients with brain tumors and with supratentorial hematomas. It is considered a false localizing neurological sign. Magnetic resonance imaging (MRI) scan has been the test of choice. The recognition of this phenomenon is important to prevent a surgical procedure on the opposite side of the lesion. The present case report describes a case of chronic subdural hematoma with a probable finding of the Kernohan-Woltman phenomenon, and it discusses its pathophysiology, imaging findings, treatment, and prognosis.

Background. Porencephaly is an extremely rare neurological disease characterized by the presence of solitary or multiple degenerative cerebrospinal fluid (CSF) cavities within the brain parenchyma. Case Report. We describe a case involving a 23-year-old male who presented with involuntary movements of the left upper limb of 6 months’ duration. A diagnosis of porencephaly was confirmed by magnetic resonance imaging (MRI). Conclusion. The rarity of occurrence and atypical presentation of such a lesion present a challenge to clinicians. Little is known about the pathogenesis and appropriate management of porencephaly. Further studies of the implications of porencephaly for neurodevelopment and behavior are needed.

Gadolinium (Gd) is a based contrast agent is used for Magnetic Resonance Imaging (MRI). In India, gadobutrolhas been is approved for MRI of the Central Nervous System (CNS), liver, kidneys, and breast. It has been noted in several studies that the accumulation of gadolinium occurs in different structures in the brain. Patients with Multiple Sclerosis (MS) are regularly followed up with MRI scans and MRI with contrast enhancement is the most common method of distinguishing new-onset pathological changes. Developments in technology and methods in artificial intelligence have shown that there is reason to map out the X-ray technician’s work with examinations and medicines administered to patients may be altered to prevent the accumulation of gadolinium.

Gardner Syndrome is a rare disease with clinical manifestations of familial intestinal polyposis with osteomas. Cutaneous and subcutaneous lesions are common and epidermoid cyst is a characteristic dermatologic finding. This case report presents a novel finding of an intracranial epidermoid situated in the fourth ventricle in a patient with Gardner Syndrome. This intracranial epidermoid has been followed with sequential magnetic resonance imaging (MRI) for 10 years with progressive growth of the lesion. This suggests the conservative management is an option in patients with an enlarging epidermoid cyst in the fourth ventricle. Plain language summary Non-operative treatment of a cyst in the brain in a syndrome called Gardner syndrome. What is Gardner syndrome? Gardner syndrome is a rare disease and form of familial adenomatous polyposis (FAP) that is characterized by multiple small growths of cells (polyps) in the colon and various types of tumors, both noncancerous (benign) and cancerous (malignant). It is caused by changes (mutations) in the APC gene. Abnormal changes on the skin and under the skin are common as well as growths called epidermoid cysts. The cysts develop when cells that are meant to become skin, hair, and nails (epithelial cells) are trapped among the cells that form the brain. Epidermoid brain cysts may be diagnosed by magnetic resonance imaging (MRI) and computerized tomography (CT) scans. Typical treatment usually involves surgery. What was the aim of this case report? To present a different management strategy for patients with Gardner Syndrome with epidermoid brain cysts. How was this patient treated? This patient is the first patient with Gardner Syndrome with a very rare epidermoid brain cyst reported to be treated in a conservative manner. The patient was monitored for 10 years with regular MRI scans and the cyst continued to grow over this time. Despite this growth the patient has shown no signs of a buildup of fluid in the cavities deep within the brain (called hydrocephalus). The patient experienced nonfocal headaches, which were relieved with medication so doctors decided not to surgically remove the cyst. Why is this case important? Conservative management of epidermoid brain cysts in Gardner patients has not been reported before. This case report shows that conservative management may be an alternative option for patients with a growing epidermoid cyst in the fourth ventricle of the brain. Conservative treatment is designed to avoid invasive treatments or surgery and provides a different option for patients who are unable to have surgery.

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.

Abstract Background Management of postoperative chylothorax usually consists of nutritional regimens, pharmacological therapies such as octreotide, and surgical therapies such as ligation of thoracic duct, but a clear consensus is yet to be reached. Further, the variation of the thoracic duct makes chylothorax difficult to treat. This report describes a rare case of chylothorax with an aberrant thoracic duct that was successfully treated using focal pleurodesis through interventional radiology (IVR). Case presentation The patient was a 52-year-old man with chylothorax after a thoracoscopic oesophagectomy for oesophageal cancer. With conventional therapy, such as thoracostomy tube, octreotide or fibrogammin, a decrease in the amount of chyle was not achieved. Therefore, we performed lymphangiography and pleurodesis through IVR. The patient appeared to have an aberrant thoracic duct, as revealed by magnetic resonance imaging (MRI); however, after focal pleurodesis, the leak of chyle was diminished, and the patient was discharged 66 days after admission. Conclusions Chylothorax remains a difficult complication. Focal pleurodesis through IVR can be one of the options to treat chylothorax.

AbstractThe computed tomography (CT) scan of a 19-year-old man who died from an occipito-frontal gunshot wound presented an impressive radiating fracture line where the entire sagittal suture burst due to the high intracranial pressure that arose from a near-contact shot from a 9 mm bullet fired from a Glock 17 pistol. Photorealistic depictions of the radiating fracture lines along the cranial bones were created using three-dimensional reconstruction methods, such as the novel cinematic rendering technique that simulates the propagation and interaction of light when it passes through volumetric data. Since the brain had collapsed, depiction of soft tissue was insufficient on CT images. An additional magnetic resonance imaging (MRI) examination was performed, which enabled the diagnostic assessment of cerebral injuries.

This is a case of a 52-year-old man with a past medical history of 2 episodes of coital thunderclap headaches as well as recent cocaine, marijuana, and pseudoephedrine use, who presented with sudden, sharp, posterior headache associated with photophobia and phonophobia. His initial magnetic resonance imaging (MRI) of the brain, magnetic resonance angiography (MRA) of the head, and magnetic resonance venography (MRV) of the head were all normal as well as a normal lumbar puncture. Given the multiple risk factors for reversible cerebral vasoconstriction syndrome (RCVS), the patient was treated for suspected RCVS, despite the normal imaging. Repeat MRI brain 3 days after hospital admission demonstrated confluent white matter T2 hyperintensities most prominent in the occipital lobes, typical of posterior reversible encephalopathy syndrome (PRES). Repeat MRA of the head 1 day after discharge and 4 days after the abnormal MRI brain showed multisegment narrowing of multiple arteries. This case demonstrates that RCVS may present with PRES on MRI brain and also exemplifies the need to treat suspected RCVS even if imaging is normal, as abnormalities in both the MRI and the MRA may be delayed.

AbstractThe present study is a case report of vulvar lipoma. The vulva is a rare site for the development of lipomas, and the aim of the study is to determine if the current imaging modalities can diagnose lipomas correctly. A 43-year-old patient presented with a painless, slowly progressive, oval, mobile and non-tender right vulvar mass compressing the vagina and totally covering the introitus. Both the ultrasonography and magnetic resonance imaging (MRI) exams suggested the diagnosis of lipoma. Surgical excision was performed, and the histopathological examination of the mass confirmed a lipoma.
