“…It typically has a prominent central artery and a scar with radiating fibrous septa. Due to the lack of portal veins, it has a centrifugal (spoke-wheel) flow [6, 8-9]. The main differential diagnosis of the typical FNH includes hepatic adenoma, which on contrast-enhanced imaging demonstrates similar enhancement in the arterial phase but centripetal filling (outside-in) in the portal phase.…”

An incidental liver mass was discovered in a 65-year-old male during a routine ultrasound (US) check-up of his hiatal hernia. The mass, which showed no malignant characteristics, was interpreted as a focal nodular hyperplasia (FNH). Due to normal blood tests and tumor marker levels, as well as the patient's asymptomatic presentation, only regular monitoring was performed. At a check-up 18 months later, CT examination indicated hepatocellular carcinoma (HCC). Surgery was no longer possible due to diffuse liver involvement. Transarterial chemoembolization (TACE) and chemotherapy were started. A possible metastasis to the right adrenal gland was detected. The patient started to experience headaches, vertigo, paresthesia, and pain of the right jaw. A CT scan of the head showed a mass in the right masticatory space. A CT-guided biopsy confirmed a HCC metastasis.

“…Beyond improved fascicular identification [105], ultra-high-resolution US of nerves (figure 6) has rarely been studied. Frequencies are generally described as being between 30 and 100 MHz [159], although no agreed threshold exists, and resolution as high as 20 µm [159][160][161], as compared to standard clinic based USs with 10 MHz probes at around 150 µm, 100 µm with 17 MHz probes, and 73 µm with 22 MHz probes, at shallow depths [162,163]. However, recently, Brya et al [164] examined the correlation of intra-fascicular 30 MHz US backscatterbased coefficients to collagen and myelin content in cadaver ulnar nerve fascicles.…”

A scoping review of current and emerging techniques for evaluation of peripheral nerve health, degeneration and regeneration: part 2, non-invasive imaging

Peripheral neuroregenerative research and therapeutic options are expanding exponentially. With this expansion comes an increasing need to reliably evaluate and quantify nerve health. Valid and responsive measures of the nerve status are essential for both clinical and research purposes for diagnosis, longitudinal follow-up, and monitoring the impact of any intervention. Furthermore, novel biomarkers can elucidate regenerative mechanisms and open new avenues for research. Without such measures, clinical decision-making is impaired, and research becomes more costly, time-consuming, and sometimes infeasible. Part 1 of this two-part scoping review focused on neurophysiology. In Part 2, we identify and critically examine many current and emerging non-invasive imaging techniques that have the potential to evaluate peripheral nerve health, particularly from the perspective of regenerative therapies and research.
