Imaging features of rare mesenychmal liver tumours: beyond haemangiomas. [PDF]

open access: yes, 2017
Tumours arising from mesenchymal tissue components such as vascular, fibrous and adipose tissue can manifest in the liver. Although histopathology is often necessary for definitive diagnosis, many of these lesions exhibit characteristic imaging features.

Flow‐suppressed 2D spin‐echo imaging with high tolerance to B1 inhomogeneity using hyperbolic secant pulses

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 172-187, January 2026.
Abstract Purpose To demonstrate flow‐suppressed two‐dimensional (2D) spin‐echo and spin‐echo diffusion echo‐planar imaging (EPI) sequences using hyperbolic secant (HS) pulses for both π/2 excitation and π refocusing. Theory and Methods A theoretical framework to derive phase dispersion of moving spins under π/2 excitation and π refocusing using HS ...

Free‐breathing phase‐sensitive inversion recovery T1‐weighted imaging for improved visualization of focal liver lesions

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 314-331, January 2026.
Abstract Purpose Gadoxetic acid‐enhanced hepatobiliary phase T1‐weighted (T1w) MRI is effective for the detection of focal liver lesions but lacks sufficient T1 contrast to distinguish benign from malignant lesions. Although the addition of T2, diffusion, and dynamic contrast‐enhanced T1w imaging improves lesion characterization, these methods often do

Differential Prox-1 and CD 31 expression in mucousae, cutaneous and soft tissue vascular lesions and tumors [PDF]

open access: yes, 2005
The study of lymphatic vessels and lymphatic tumors has been hampered with difficulty due to the overlapping morphological features between blood and lymphatic endothelial cells, as well as to the lack of specific lymphatic endothelial markers.

Familial Cerebral Cavernous Malformations: Pathophysiology, Genetics, Biomarkers, and Treatment Perspectives

open access: yesJournal of Neurochemistry, Volume 170, Issue 1, January 2026.
Cerebral cavernous malformations (CCMs) are vascular lesions in the brain caused by inherited genetic mutations in the CCM1/2/3 genes that disrupt normal blood vessel function. This work demonstrates that these mutations lead to endothelial dysfunction, inflammation, and iron accumulation, which can be detected by magnetic resonance imaging (MRI) and ...

Symptomatic cavernous hemangioma of fronto-parietal region of the brain in a young female patient – a case report

open access: yesJournal of Education, Health and Sport, 2018
Introduction: Cavernous hemangioma is a bening blood vessel malformation that can be located in the central nervous system. Although most patients who are found to have a CNS hemangioma are asymptomatic, the entity can cause a wide spectrum of symptoms ...

Liver haemangioma: common and uncommon findings and how to improve the differential diagnosis [PDF]

open access: yes, 2007
Haemangiomas are common focal liver lesions, generally detected in the work-up of asymptomatic patients. From the pathological point of view, they can be classified as small (capillary) or large, with cavernous vascular spaces that may show thrombosis ...

Left hepatic trisegmentectomy [PDF]

open access: yes, 1982
Left hepatic trisegmentectomy was successfully performed upon four patients in whom the true left lobe of the liver and all, or part, of the anterior segment of the right lobe of the liver were removed in continuity.

Intraosseous Hemangioma of the Inferior Turbinate [PDF]

open access: yes, 2010
The nasal cavity harbors an enormous variety of neoplasms, including epithelial and mesenchymal tumors. Hemangioma is an infrequent mesenchymal tumor of the nasal cavity, mostly arising in the mucosa and rarely in the bones.

Detection of GJA4 Mutation in a Sinonasal Angioleiomyoma

open access: yesCase Reports in Pathology, Volume 2026, Issue 1, 2026.
Background Angioleiomyomas are ubiquitous perivascular tumors, and harbor recurrent GJA4 mutations identified in the orbitary and dural locations. Herein, we reported for the first time a sinonasal angioleiomyoma presenting this typical genetic alteration. Case Presentation A 76‐year‐old man with an unremarkable medical history presented with a chronic
