BACKGROUND: Hepatic tuberculosis (TB) shows non-specific symptoms, and liver imaging may provide diagnostic clues. Here we describe a series of patients with hepatic TB showing characteristic radiological findings. METHODS: Single-centre retrospective evaluation of patients with hepatic TB diagnosed over a period of 16 years who underwent ultrasound, computed tomography (CT) and/or magnetic resonance imaging (MRI). Hepatic lesions were classified as miliary, nodular, serohepatic or cholangitis...

A 21 year old male with no relevant medical history presented to our Institution for further assessments of a right paracardiac mass founded on a chest X-ray. Chest computed tomography revealed a wide median defect of the diaphragm at the level of xiphoid process of the sternum, with the herniation of omental fat tissue in the mediastinum. Cardiac magnetic resonance confirmed the presence of a huge hernia originating from the foramen of Morgagni (sterno-costal hiatus), displacing the heart leftwards and posteriorly and compressing the right ventricle (RV), giving to it a tubular shape...

BACKGROUND: Bipolar disorder (BD) is a severe and disabling mental illness, which is characterized by selective gray matter (GM) and white matter (WM) brain alterations, as observed by several imaging studies. However, the clinical course of the disease is uncertain and can vary across BD patients, with some having a benign course and others a severe disability. In this perspective, magnetic resonance imaging (MRI) can help identifying biological markers of worse prognosis. METHODS: The present selected review aimed at summarizing structural MRI (sMRI) studies exploring the correlation between brain morphology and features of clinical outcome, which could include treatment response, cognitive impairment and global functioning...

Osteochondroma is the most common benign bone tumor but it rarely arises from the scapula. Scapulothoracic bursitis is quite rare and osteochondroma is one of the unusual causes of this condition. Synovial chondromatosis may occur extremely uncommonly in this bursa. We reported an unusual case of scapulothoracic bursitis with synovial chondromatosis which is caused by osteochondroma. To the best of our knowledge, there is no defined chondromatosis in the scapulothoracic bursa secondary to scapular osteochondroma in the literature...

Common postictal MRI findings include transient cortical T2 hyperintensity, restricted diffusion, and gyral and/or adjacent leptomeningeal contrast enhancement. In certain uncommon pathological conditions, other signal abnormalities can be present, suggesting a different underlying pathogenic mechanism. We report the case of a 66-year-old man, recently diagnosed with diabetes mellitus type 2, presenting with new-onset visual and auditory hallucinations, "absence" seizures, and repeated peaks of hyperglycaemia without hyperketonaemia or increased serum osmolarity...

Aims: Hypertension is one of the main risk factor for dementia. The subtle damage provoked by chronic high blood pressure in the brain is usually evidenced by conventional magnetic resonance imaging (MRI), in terms of white matter (WM) hyperintensities or cerebral atrophy. However, it is clear that by the time brain damage is visible, it may be too late hampering neurodegeneration. Aim of this study was to characterize a signature of early brain damage induced by hypertension, before the neurodegenerative injury manifests...

BACKGROUND: Cerebral small vessel disease (CSVD) comprises a variety of disorders affecting small arteries and microvessels of the brain, manifesting as white matter hyperintensities (WMHs), cerebral microbleeds (CMBs), and deep brain infarcts. In addition to its contribution to vascular dementia (VaD), it has also been suggested to contribute to the pathogenesis of Alzheimer's disease (AD). METHOD: A systematic review of the literature available on Medline, Embase and Pubmed was undertaken, whereby CSVD was divided into WMHs, CMBs and deep brain infarcts...

Both white matter hyperintensities (WMHs) and lacunar infarctions (LIs) are magnetic resonance imaging (MRI) markers of cerebral small vessel disease (SVD). However, the association between WMH and LI remains unclear. In this study, we asked whether WMH progression is related to LI occurrence using retrospective data. Overall, 8475 WMH patients with at least two MRI images were screened, and 187 patients were included in the final study; 76 patients had WMH with LI (WL), and 111 patients had WMH without LI (WOL)...

Atrial myxoma is a rare cause of stroke. In this report we present the case of a 52-year-old female patient who went to hospital suffering from a headache. Her neurological examination was normal except for a positive Babinski sign on the left. In the superolateral of the right, a Sylvian fissure consistent with a thrombosed aneurysm was detected using computerised tomography (CT). Diffusion MRI showed an acute infarction on the right MCA area. Transthorasic Echocardiography and ECG were normal. A -16×4 mm-sized fusiform perpendicular aneurysm on the M2 segment Sylvian curve of right MCA and a -6×4 mm-sized dissecting aneurysm on P3 segment of the left posterior cerebral artery (PCA) were observed in cerebral angiography...

Bilateral basal ganglia lesions are a common non-specific finding seen in many diseases. One of the differential diagnoses for it, in a child, is kernicterus occurring due to hyperbilirubinemia. Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common cause of severe hyperbilirubinemia. A 1-year old child presented to the hospital with history of generalized dystonia in the previous 3 days. MRI showed evidence of symmetrical lesions in bilateral globus pallidus, which were hyperintense on T2/FLAIR and isointense on T1...
