Vascular lesions: Hemangioma or venous malformation?

We present a case of a 62-year-old female who was incidentally found to have a venous malformation. Venous malformations are part of a larger category of slow flow vascular malformations and are associated with various familial syndromes and localized intravascular coagulation. Venous malformations were often misdiagnosed as hemangiomas; however, the treatment modalities of vascular malformations and hemangiomas vary significantly.

Heroin-induced leukoencephalopathy: Chasing the imaging findings.

We present a case of a 29-year-old male who was brought into the hospital due to unresponsiveness and found to have heroin inhalational leukoencephalopathy (HLE). HLE is one component of a broad spectrum of opioid encephalopathies that is associated with heroin inhalation and other opioids. There is considerable overlap of HLE with other toxic and hypoxic-ischemic encephalopathies; however, the specific territories of brain involvement help distinguish it from other cerebral insults.

Pfeiffer syndrome in an adult with previous surgical correction: A case report of CT findings.

Pfeiffer syndrome, affecting roughly 1 in 100,000 individuals is characterized by acrocephalosyndactyly - the closure of skull sutures (craniosynostosis). These acrocephalosyndactyly syndromes which are often sporadic de novo but also autosomal dominant in inheritance can be characterized by the fact that they often involve FGFR and TWIST genes. In the presented case, a 27-year old male level three trauma admission displayed skull abnormalities on physical examination that history taking confirmed was the result of pediatric surgically corrected Pfeiffer syndrome.

COVID-19-associated encephalopathy with fulminant cerebral vasoconstriction: CT and MRI findings.

Severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) can cause various mild to severe neurologic symptoms, leading to significant morbidity and mortality. We hereby present a fatal case of a 50-year-old male health care provider, admitted due to altered mental status due to encephalopathy, cerebral edema, and fulminant cerebral vasoconstriction caused by SARS-Cov-2. Our case highlights the importance of considering SARS-Cov-2 infection in the differential diagnosis for patients with unexplained central nervous system dysfunction and cerebral edema to prevent delayed diagnosis and render rapid treatment.

Remote cerebellar hemorrhage: A case report.

Remote Cerebellar Hemorrhage is a rare entity that manifests spontaneously after supratentorial craniotomy and spinal surgeries. We present a 53-year-old male who was admitted due to subdural hematoma along the left frontoparietotemporal convexity. After treatment of the subdural hematoma with craniotomy and evacuation, he developed remote cerebellar hemorrhage 1 week later.

The Missing Link: A Case of Absent Pituitary Infundibulum and Ectopic Neurohypophysis in a Pediatric Patient with Heterotaxy Syndrome.

We report a case of absent pituitary infundibulum and ectopic neurohypophysis in a 4-year-old patient presenting clinically with hypopituitarism as well as heterotaxy syndrome complicated by global developmental delay and growth retardation. The clinical and laboratory workup of our patient suggested underlying hypopituitarism related to either congenital or acquired pathology, necessitating MRI to distinguish between them. We explain the various structural causes of hypopituitarism and detail how to predict the MRI findings and treatment, based on a fundamental understanding of the anatomy and pathophysiology of the hypothalamic pituitary axis and distinguishing anterior versus posterior pituitary hormone derangements.

The Media Response to the ACGME's 2017 Relaxed Resident Duty-Hour Restrictions.

Purpose: In March 2017, the ACGME relaxed resident duty-hour restrictions to allow first-year residents to work 24-hour shifts, affecting the internship experience of incoming radiology residents. The aim of this study was to assess the media response to this duty-hour change, comparing news articles with favorable and unfavorable views.

Methods: Google News was used to identify 36 relevant unique news articles published over a 4-week period after the announcement.

Atypical spine involvement of Erdheim-Chester disease in an elderly male.

Erdheim-Chester disease is a rare form of non-Langerhans histiocytosis presenting in the 5th through 7th decades of life. Osseous manifestations include symmetrical sclerosis of the long bones and, rarely, the spine. Central nervous system disease commonly affects the white matter tracts as well as the orbits, but epidural disease is rare.
