Pacinian corpuscles, the main touch receptors to pressure and vibration, are ubiquitous in the deep dermis and hypodermis of the fingers and palms. [] Key Result Pre-operative MRI examinations in these patients showed T2 hyperintense subcutaneous palmar nodules corresponding to these corpuscles in a pattern identical to those seen incidentally in other patients. Descriptions from the dermatopathological and orthopedic literature closely correspond to our MRI observations. Based on these data, we hypothesize…
Normal Pacinian corpuscles in the hand: radiology–pathology correlation in a cadaver study
TLDR
On MRI, normal Pacinian corpuscles appear as round or oval, T2-hyperintense subcutaneous nodules in the palms, clustered around the metacarpophalangeal joints, and should not be mistaken for pathological conditions.
Macrodystrophia Lipomatosa of the Foot: A Case Report of MRI and Histologic Findings Including Pacinian Corpuscle Abnormalities.
TLDR
Peculiar abnormalities of PCs in MDL underline nerve damage and may be a contributing factor in the pain associated with this unusual condition.
Novel observations of Pacinian corpuscle distribution in the hands and feet based on high-resolution 7-T MRI in healthy volunteers
TLDR
This work demonstrates that the complex network of Pacinian corpuscles in hands and feet can be examined with three-dimensional Dual Echo Steady State MR imaging at 7 T, while previous dedicated MRI reports were either limited to two-dimensional images or focused on the hands.
Painful Vater-Pacini neuroma of the digit in neurofibromatosis type 1
TLDR
The discussion addresses the difficulties of terminology and current diagnostic procedures for differentiating small nodular masses of the palm and digits in patients with neurofibromatosis type 1.
Multimodality Pitfalls of Wrist Imaging With a Focus on Magnetic Resonance Imaging: What the Radiologist Needs to Know.

TLDR
In order to accurately diagnose true pathology at wrist imaging, it is imperative that the radiologist be familiar with the pitfalls discussed throughout this manuscript that may mimic disease.
Distribution, fine structure, and three-dimensional innervation of lamellar corpuscles in rat plantar skin.
TLDR
The results demonstrate that the type of lamellar corpuscles in the dermal papillae of rat plantar skin is a simple corpuscle and implies that their distribution pattern in the plantarskin is convenient for efficient sensing and transmission of mechanical stimuli from the ground.
Vibroacoustic treatment and self-care for managing the chronic pain experience: An operational model
TLDR
This dissertation addresses the question of whether practitioner-led VA treatment can be used to manage the psychophysiological symptoms of chronic pain, and whether an adjunct self-care phase is helpful in prolonging the effects.
Vibroacoustic treatment to improve functioning and ability to work: a multidisciplinary approach to chronic pain rehabilitation
TLDR
In four single cases, this study shows functioning, pain, and depression improved after Vibroacoustic treatment with self-care, and the greatest improvement was from the practitioner-led sessions, butSelf-care was beneficial for pain relief and relaxation.

Pacinian corpuscle neuroma of digital nerves.
TLDR
A case is presented in which the patient's chief complaint was pain and localized tenderness in the hand which interfered with normal activity and abnormalities of pacinian corpuscles attached to the median digital nerve in the form of a grape-like cluster and a single enlarged corpuscle beneath the epineurium were presented.
Pacinian corpuscle neuroma of digital nerves.
TLDR
A case is presented in which the patient's chief complaint was pain and localized tenderness in the hand which interfered with normal activity, and abnormalities of pacinian corpuscles attached to the median digital nerve in the form of a grape-like cluster and a single enlarged corpuscle beneath the epineurium were presented.
An Extraordinary Association of Glomus Tumor and Pacinian Hyperplasia in the Hand of a Female Patient
TLDR
A 65-year-old woman with a history of hand trauma and a 1-year chief complaint of tingling, pain, and burning sensations in her proximal thumb underwent exploration of the digital nerve after an x-ray and 2 magnetic resonance imaging examinations failed to detect a mass.
Painful hyperplasia and hypertrophy of pacinian corpuscles in the hand: report of two cases with immunohistochemical and ultrastructural studies, and a review of the literature.
TLDR
Investigations indicated that the lump replicates the structure of enlarged pacinian corpuscles and should not be considered as a real tumor, nor connected to neurofibromatosis, and no recurrence was observed after surgical excision.
Uncommon Number and Distribution of the Pacinian Corpuscles in a Human Hand
Hyperplasia and Hypertrophy of Pacinian Corpuscles: A Case Report
Abstract:The proliferation of Pacinian corpuscles is a rare benign lesion that occurs frequently in the fingers of hands, with the only clinical sign of pain when a drastic temperature change
Blood-nerve barrier in the Vater-Pacini corpuscle of cat mesentery
TLDR
Investigations suggest strongly that the Vater-Pacini corpuscle lamellae enfolding the nerve terminal form an effective diffusion barrier against the permeation of tissue fluids, thus preserving the corpuscle internal circumference.
In vivo magnetic resonance micro-imaging of the human toe at 3 Tesla.
Developmental and lesion-induced changes in the distribution of the glucose transporter Glut-1 in the central and peripheral nervous system
TLDR
Glut-1 seems to reflect the quality of an adult, mature perineurial and blood-nerve barrier in the normal central and peripheral nervous system of young and adult animals and compared with changes after nerve injury.
In vivo MRI of the human finger at 7 T
TLDR
To demonstrate a dedicated setup for ultrahigh resolution MR imaging of the human finger in vivo, a dedicated set-up is presented at the European Society for Neuroscience meeting in Brussels.
