Best zero level for external ICP transducer

ConclusionsEAM and glabella are defined anatomical structures representing BC when strict supine or lateral but with 12  mmHg variation with different head positions used in clinical practice. The OM line follows Monro at head elevation, but not when the head is turned. When the highest external point on the head is used, ICP values at brain surface as well as Monro and BC are underestimated. This underestimation is fairly constant and, when corrected for, provides the most exact ICP reading.

This study compares the incidence of new-onset symptoms within 24 hours after enhanced magnetic resonance imaging (eMRI) with intravenous administration of gadodiamide or gadoterate meglumine compared with a control group undergoing unenhanced MRI (uMRI). Materials and Methods A prospective cohort study (n = 1088 patients) was designed to assess the incidence of symptoms within 24 hours after administration of gadodiamide or gadoterate meglumine. The participants underwent a structured questionnaire by phone call before and 24 hours after the MRI scan to check for symptoms that were not present before the scan. The ques...

lah O Abstract A 72-year-old female with no relevant medical history consulted in the emergency room for a two-week history of headache, vomiting and gait disturbance. Head CT scan revealed obstructive hydrocephalus secondary to a pineal mass with compression of the third ventricle. Magnetic Resonance showed another mass located in the right Lushcka foramen. Endoscopic third-ventriculostomy and biopsy of pineal mass were performed. Pathological analysis was consistent with metastasis of carcinoma. Full-body CT scan showed a lung mass related to primary carcinoma. The patient received systemic treatment for metasta...

Authors: Ayubcha C, Hosoya H, Seraj SM, Zadeh MZ, Werner T, Alavi A Abstract Fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) imaging was conceived in the early 1970 by investigators at the University of Pennsylvania as a research technique to measure brain metabolism and function by employing a non-invasive imaging approach. Soon after the introduction of whole-body PET instruments, 18F-FDG was utilized in the assessment of a variety of solid tumors and certain hematological malignancies. Yet, the role of 18F-FDG in assessing benign and uncommon malignant disorders of the bone marrow has n...

Conclusions: Correctly identifying an infectious versus tumor etiology is important. Research has been carried out to employ diffusion-weighted imaging (DWI) in differentiating the variable radiological findings. The role of DWI in diagnosing bacterial abscess is more commonly seen in comparison to fungal abscess. DWI has a high diagnostic potential, but more works need to be done. PMID: 30788184 [PubMed]

ConclusionSince there is often times a clinico-radiological discordance they are generally incidental findings in majority of cases. While complete surgical excision is the treatment of choice for the symptomatic cysts, cystic fluid diversion presents a better compromise nevertheless in cases where this may not be achieved.

Tacrolimus-induced encephalopathy presents with acute neurological symptoms such as headache, seizures, visual disturbances, hemiplegia, and altered mental status. A 60-year-old woman, presented to our clinic with a 4-month history of severe headache. She recently underwent kidney transplantation and was taking tacrolimus. MRI scan showed diffuse and symmetric alterations involving both supratentorial and infratentorial white matter. Cerebral spinal fluid assessment for infectious diseases were negative but elevated total protein level and oligoclonal bands positivity were reported.

CONCLUSION: It is important to note MRI changes specific to cystic meningioma and include meningiomas in the differential diagnosis of intracranial cystic lesions. The use of sodium fluorescein (Na-Fl) under a YELLOW 560nm microscope filter is a useful tool to differentiate the brain-tumor interface, as well as to identify the cyst wall in order to fully resect the tumor with the cystic component to avoid recurrence and achieve better clinical results.

TheWall Street Journaltoday profiles South Africa ’s electric power company, Eskom. What a mess—something we have seen many times with government-owned businesses. Eskom has a bloated workforce, provides terrible service, fails to maintain its facilities, and is transmitting economic damage in every direction. It has rotten management and appar ently corrupt dealings with politicians.Three decades afterMargaret Thatcher this should not be happening. Governments should not own businesses that can earn revenues in the marketplace. For citizens, there is no advantage to government ownership —there is only hi...

Rationale: Hepatocellular carcinoma (HCC) is the fifth most common cancer and third leading cause of cancer-related deaths worldwide. Nasopharyngeal metastasis of hepatocellular carcinoma is very rare. This is the first report of posttransplantation nasopharyngeal metastasis. Patient concerns: A 45-year-old man with a history of hepatitis B related hepatocellular carcinoma (HCC) in the right segment of the liver received an orthotopic liver transplant. Two year after the transplantation, he suffered from severe headache, and head contrast enhanced CT scans did not show clues for brain or skull metastasis. Then he deve...
