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.

CHANTER Syndrome and mesenteric ischemia presenting concurrently, a case report and literature review.

We present a case of a 70-year-old male who was brought to the hospital with altered mental status and was found to have 2 serious complications of cocaine use which are Cerebellar Hippocampal and Basal Nuclei Transient Edema with Restricted diffusion (CHANTER) syndrome and mesenteric ischemia. CHANTER syndrome is a recently described constellation of radiologic and clinical findings and has a strong association with opiates, and/or other drugs of abuse, including cocaine. Even though CHANTER has many similarities with other ischemic, anoxic, and/or toxic injuries related to substance abuse such as clinical presentation and restricted diffusion on magnetic resonance imaging (MRI); the typical distribution of affected regions in the brain is helpful in differentiating from other injuries.

A case of spontaneous intracranial hypotension in a 45-year-old male with headache, behavior changes and altered mental status.

Spontaneous intracranial hypotension is a rare disease that results from low cerebrospinal fluid (CSF) volume caused by leakage of CSF from the spine in the absence of lumbar puncture, spine surgery, or intervention. The most common presentation is the headache that is usually but not invariably orthostatic. The underlying pathology is a CSF leak resulting from dural weakness involving the nerve root sleeves, ventral dural tears associated with calcified disc herniations, or CSF venous fistula.

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.

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 accuracy of [(18)F]fluorodeoxyglucose positron emission tomography as confirmed by biopsy in the diagnosis of spine metastases in a cancer population.

Objective: To determine the accuracy of [(18)F]fluorodeoxyglucose (FDG) positron emission tomography (PET) in the diagnosis of vertebral metastases in patients with cancer using needle-biopsy results and patient follow-up data.

Methods: A retrospective chart review of all patients who underwent a needle biopsy of a spinal lesion and underwent FDG-PET within 6 weeks of the biopsy was performed. Biopsy results and magnetic resonance imaging and computed tomographic appearance of the biopsied lesion, as well as long-term clinical follow-up data, were recorded for each patient.

Percutaneous CT-guided biopsy of osseous lesion of the spine in patients with known or suspected malignancy.

Background And Purpose: CT-guided spinal biopsy (CTGSB) is considered a safe and accurate procedure. Our goal was to determine the accuracy of a CTGSB of osseous spinal lesions in patients with known or suspected underlying malignancy in reference to major variables such as the radiographic appearance of the biopsied lesion and its location within the spinal column.

Methods: We retrospectively reviewed results of 410 consecutive percutaneous CTGSB procedures of osseous spinal lesions.
