This document discusses treatment options for middle cerebral artery (MCA) aneurysms, specifically clipping versus coiling. It provides data from multiple studies showing improved outcomes with coiling compared to clipping, including lower rates of poor outcome, complications, and rebleeding. The document also reviews new endovascular devices that have increased the feasibility of coiling for more complex MCA aneurysms. It concludes that while both treatments are reasonable options, coiling is now generally preferred for MCA aneurysms due to improved outcomes demonstrated in clinical trials and registry data.
The medical document discusses three findings: a right varicocele, dilated veins within the right testis; rette testis dilatation, enlarged veins within the network of veins draining the testis; and an epididymal cyst, a fluid-filled sac within the epididymis, the coiled tubular structure that collects and transports sperm from the testis.
O documento discute vários casos de pacientes que sofreram recidivas de meningiomas ou desenvolveram múltiplos meningiomas. Detalha tratamentos como cirurgia e embolização para remover os tumores e controlar o crescimento de novos tumores. Também menciona um caso raro de múltipla meningiomatose.
The document discusses two anatomical structures: Type 3 Frontal Cell and Agger nasi. Type 3 Frontal Cell refers to a specific type of frontal sinus cell located in the frontal bone above the nose. Agger nasi refers to a small bony projection located in the nasal cavity near the front of the nasal septum.
A patient presented with a hypoglossal nerve schwannoma located in the cisternal segment that was imaged with various MRI sequences including 3D CISS, T1 TSE, FLAIR, VIBE, post-gadolinium SPACE, and post-gadolinium to characterize the tumor and its relationship to surrounding structures.
Congenital Cholesteatoma of the Mastoid Bone on CT& MRIRuth Martín Boizas
Congenital cholesteatoma of the mastoid bone is a rare, non-epithelial cyst or tumor that exists in the mastoid bone at birth. Computed tomography (CT) and magnetic resonance imaging (MRI) are useful in evaluating congenital cholesteatoma and can help determine the extent of involvement of the mastoid bone and surrounding structures. Surgical removal is usually required to prevent complications like bone erosion and hearing loss.
A patient was experiencing a relapse of mantle B-cell lymphoma that had spread outside the spinal cord into the extradural space and spinal foramina. Magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT) scans using fat saturated and non-fat saturated post-gadolinium T1 spin echo sequences were performed to evaluate the extent of the relapse.

An arachnoid cyst is a fluid-filled sac that develops within the arachnoid membrane layers that surround the brain or spinal cord. Magnetic resonance imaging (MRI) is often used to diagnose arachnoid cysts as it can clearly visualize the size, location, and other characteristics of the cyst. MRI is a useful non-invasive tool to evaluate arachnoid cysts and help determine if any treatment may be needed.
This document discusses the differences between a lacunar infarct and a Virchow-Robin space as seen on CT and MRI scans. A lacunar infarct is typically larger than 5mm, asymmetric, located in the superior two-thirds of the putamen, and not isointense with CSF. In contrast, a Virchow-Robin space is usually less than 5mm, symmetric, located in the inferior third of the putamen, and isointense with CSF. While these are the general differences, the document notes there was an asymmetric case that was unusual.
Alzheimer's disease causes brain atrophy that can be seen on imaging tests. It initially affects the hippocampus and entorhinal cortex, then spreads to the posterior cingulum, medial temporal lobe, and insular cortex. Over time, atrophy progresses to the prefrontal and orbitofrontal cortices bilaterally in a symmetric and diffuse pattern.
I have decided to use this MRI protocol to study patients with clinical suspicion of Mild Cognitive Impairment & Dementia.
1.2 mm isotropic sagittal T1 3D MP-RAGE is centered on thalamus to be used for Voxel Based Morphometry, if necessary.
Axial T2 GE is used to discover small blood foci secondary to amyloid angiopathy.
DTI is used for VOIs on previously determined strategic areas to try to diagnose the type of dementia by image findings.

A patient presented with spinal tuberculous leptomeningitis and subdural empyema as seen on MRI, with leptomeningeal enhancement and lung cavitated nodules. The patient underwent posterior laminectomy for the spinal condition. Follow up MRIs one month and three weeks later showed progression of the leptomeningeal nodular enhancement and a new subdural empyema, indicating active intraspinal tuberculosis despite surgery.
