Lumbar Osteophyte Avid on 68Ga-Prostate-Specific Membrane Antigen PET/CT.

A 75-year-old man with recently diagnosed high-risk prostate cancer was referred for primary staging with Ga-prostate-specific membrane antigen (PSMA) PET/CT. The scan revealed intense Ga-PSMA uptake in a lumbar osteophyte on the right side of level L2/L3, whereas several other spinal osteophytes showed no Ga-PSMA uptake. MRI findings in the L3 vertebra was consistent with a benign Modic type 1 lesion, but MRI showed no signs of malignancy in the osteophyte with high Ga-PMSA uptake.

Magnetic resonance imaging of the intraluminal thrombus in abdominal aortic aneurysms: a quantitative and qualitative evaluation and correlation with growth rate.

Background: The role of the intraluminal thrombus (ILT) in abdominal aortic aneurysm (AAA) growth remains incompletely understood. MRI is superior to other methods in depicting the morphology of the ILT. This study brings preliminary, but novel information on the presence and morphological characteristics of the ILT and AAA growth rates in a screening cohort.

[Intervertebral discitis in children].

Intervertebral discitis is a rare disorder which is easily missed. It presents with non-specific symptoms such as irritability, abdominal pain, decreased appetite and limping. The infection parameters can be normal, and blood cultures are often negative.

A heterozygous 21-bp deletion in CAPN3 causes dominantly inherited limb girdle muscular dystrophy.

Limb girdle muscular dystrophy type 2A is the most common limb girdle muscular dystrophy form worldwide. Although strict recessive inheritance is assumed, patients carrying a single mutation in the calpain 3 gene (CAPN3) are reported. Such findings are commonly attributed to incomplete mutation screening.

Arterial ischemic stroke as a complication to disseminated infection with Fusobacterium necrophorum.

Lemierre syndrome (LS) is a rare complication of oropharyngeal and odontogenic infections in otherwise healthy young individuals. It is characterized by septic internal jugular vein thrombophlebitis and disseminated metastatic abscesses. Cerebral arterial ischemic stroke is rarely seen in LS.

Reversible magnetic resonance imaging and spectroscopy abnormalities in the course of vigabatrin treatment for West syndrome.

Transient magnetic resonance imaging (MRI) hyperintensity of globus pallidi, thalami, dentate nuclei and cerebral peduncles has recently been described in a significant number of young children during treatment with vigabatrin for infantile spasms. We describe two children with infantile spasms treated with vigabatrin, investigated with consecutive MRI as well as magnetic resonance spectroscopy (MRS). Hyperintensity developed during high dose vigabatrin treatment and remitted totally after dose reduction in one case, and cessation in the other.

[Infantile haemangioma and intracranial vascular malformation].

A two-week-old female infant presented with a large haemangioma in the left superior palpebra, preventing her from opening the eye. Cerebral magnetic resonance imaging with angiography revealed another two facial haemangiomas and agenesia of the left internal carotid artery. The combination of facial haemangiomas and intracranial vascular malformation is diagnostic for the PHACES syndrome.

The Danish PET/depression project: performance on Stroop's test linked to white matter lesions in the brain.

The Stroop test (ST) assesses the integrity of prefrontal and cingulate functioning. Patients with major depression perform poorly on the ST, pointing to disturbed function in these areas. We therefore used positron emission tomography to study 41 in-patients with major depression and 46 age- and gender-matched controls during neuropsychological activation with the ST.
