Anthony J Mells, G Max Gosey, Michael P Muldoon
Intra-articular lipoma of the hip is a rare entity, with only two reports published in the English-language literature. We present a case of successful arthroscopic resection of an intra-articular peripheral compartment lipoma in a 69-year-old woman with a coincident labral tear. This woman presented with left hip pain that developed gradually over 2 years and increased over 2 months. MRI showed a fat-intense mass in the anterior aspect of the hip joint, convincing for intra-articular lipoma. Physical examination in the operating room reproduced decreased range of motion and evidence of impingement but with a soft endpoint...

BACKGROUND: Acromegaly is a rare syndrome in which there is unregulated hypersecretion of growth hormone. The anesthetic management of patients with this disorder is particularly challenging due to pre-existing cardiovascular and respiratory dysfunction, as well as recognized difficulties with airway management. Because of the insidious progression of the disease and the presence of nonspecific signs and symptoms, diagnosis is often made late when characteristic acromegalic features become apparent...

BACKGROUND: Deficiency in 11β-hydroxylase as a cause of congenital adrenal hyperplasia is uncommon. It should be considered in the differential diagnosis of hypertension with virilization in any prepubescent child. CASE PRESENTATION: A 12-year-old Asian boy from eastern Nepal presented with pain in his abdomen and hypertension. He was raised as a male but had absent testicles since birth and had precocious puberty. Plasma testosterone, follicle-stimulating hormone, and luteinizing hormone were below baseline level...

OBJECTIVES: To determine the potential utility of the frontal assessment battery (FAB) in assessing cognitive impairments in amyotrophic lateral sclerosis (ALS), we investigated the association between the FAB score and regional gray matter volume, and ascertained whether the regional brain alterations related to cognitive impairments occur in relatively mild stage of ALS. MATERIALS AND METHODS: Twenty-four ALS patients with a Mini-Mental State Examination score of >23, a normal score on the Self-Rating Depression Scale, little or no disturbance in speech and handling utensils on the ALS Functional Rating Scale (ALSFRS), and normal measures on respiratory tests (respiratory function test and arterial blood gas analysis), and two age-matched normal control groups (one for FAB assessment and the other for brain morphometry) underwent FAB testing and structural magnetic resonance imaging...

The combination of a thorough physical exam and imaging with either MRI or pelvic ultrasound are important in pre-operative planning for deep infiltrating endometriosis. Nevertheless, the 2-dimensional rendering of the pathology by imaging does not always accurately represent intra-operative findings. An in-depth topographical relationship and extent of surrounding tissue invasion can be better appreciated from 3-dimensional modeling. A 49 year old patient with history of endometriosis and persistent pain underwent pre-operative imaging with MRI that was consistent with infiltrating endometriosis...

BACKGROUND: Surgeons often choose between 2 different approaches (anterior and posterior) for surgical treatment of degenerative cervical myelopathy on the basis of imaging features of spinal cord compression, the number of levels affected, and the spinal alignment. However, there is a lack of consensus on which approach is preferable. The objective of the present study was to use magnetic resonance imaging (MRI)-based propensity-score-matched analysis to compare postoperative outcomes between the anterior and posterior surgical approaches for degenerative cervical myelopathy...

Background Prematurity is a major risk factor for neonatal hearing loss. Recent advancements in magnetic resonance imaging (MRI) have made it possible to evaluate structural details of the membranous labyrinths in premature infants that have heretofore been inaccessible. Objective We compared the prevalence of abnormal cochlear signal intensity in premature and term neonates and evaluated for a potential link with hearing loss. Materials and methods We retrospectively reviewed 148 consecutive MR exams performed in premature (< 37 weeks' gestation) and term neonates performed over a 30-month period...

Primary somatosensory cortex (S1) processes somatosensory information and is composed of multiple subregions. In particular, tactile information from the skin is encoded in three subregions, namely Brodmann areas (BAs) 3b, 1 and 2, with each area representing a complete map of the contralateral body. Although, much is known about the somatotopic organization of the hand in human S1, less research has been carried out regarding the somatotopic maps of the foot and leg in S1. Moreover, a latero-medial S1 organization along the superior part of the postcentral gyrus has been reported when moving from hip to toes, yet to date there is no study investigating leg/foot maps within the different subregions of S1...

BACKGROUND: After appropriate initial therapy for patients with stage II-III melanoma, there is no consensus regarding surveillance. Thus, follow-up is highly variable among institutions and individual providers. The National Comprehensive Cancer Network recommends routine clinical examination and consideration of imaging for stage IIB-IIIC every 3-12 mo with no distinction between stages. Detection of recurrence is important as novel systemic therapies and surgical resection of recurrence may provide survival benefits...

Xylem flow is progressively shut down during maturation beginning with minor veins at the stylar end and progressing to major veins and finally to bundles at the stem end. This study investigates the functionality of the xylem vascular system in developing sweet cherry fruit (Prunus avium L.). The tracers acid fuchsin and gadoteric acid were fed to the pedicel of detached fruit. The tracer distribution was studied using light microscopy and magnetic resonance imaging. The vasculature of the sweet cherry comprises five major bundles...

Quantitative myocardial and blood T1 have recently achieved clinical utility in numerous pathologies, as they provide non-invasive tissue characterization with the potential to replace invasive biopsy. Native T1 time (no contrast agent), changes with myocardial extracellular water (edema, focal or diffuse fibrosis), fat, iron, and amyloid protein content. After contrast, the extracellular volume fraction (ECV) estimates the size of the extracellular space and identifies interstitial disease. Spatially resolved quantification of these biomarkers (so-called T1 mapping and ECV mapping) are steadily becoming diagnostic and prognostically useful tests for several heart muscle diseases, influencing clinical decision-making with a pending second consensus statement due mid-2017...

PURPOSE: Accurate deformable image registration is necessary for longitudinal studies. The error associated with commercial systems has been evaluated using computed tomography (CT). Several in-house algorithms have been evaluated for use with magnetic resonance imaging (MRI), but there is still relatively little information about MRI deformable image registration. This work presents an evaluation of two deformable image registration systems, one commercial (Velocity) and one in-house (demons-based algorithm), with MRI using two different metrics to quantify the registration error...

The clinical evaluation of patients with an anomalous aortic origin of a coronary artery (AAOCA), a congenital abnormality of the origin or course of a coronary artery that arises from the aorta, is challenging given its first presentation being sudden cardiac arrest in about half of the patients. Symptoms of chest pain, shortness of breath and syncope during exertion should be of concern in evaluating young athletes and nonathletes. The lack of abnormal signs on the physical exam and electrocardiogram further adds to the difficulty in establishing the diagnosis...

REVIEW
Hussein Algahtani, Bader Shirah, Ali Alassiri
Tumefactive multiple sclerosis or tumefactive demyelinating lesion (TDL) is one of the rare variants of multiple sclerosis (MS) posing a diagnostic challenge and a therapeutic enigma since it is difficult to distinguish from a true central nervous system (CNS) neoplasm or other CNS lesions on magnetic resonance imaging (MRI). The prevalence of TDL is estimated to be 1-3/1000 cases of MS with an annual incidence of 0.3/100,000. This could be an underestimate due to unavailability of a global MS registry and under-reporting of this condition...

Piriformis muscle syndrome (PMS) is difficult to diagnose by objective evaluation of sciatic nerve injury. Here we report a case of PMS diagnosed by diffusion tensor imaging (DTI) and tractography of the sciatic nerve, which can assess and visualize the extent of nerve injury. The patient was a 53-year-old man with a 2-year history of continuous pain and numbness in the left leg. His symptoms worsened when sitting. Physical examination, including sensorimotor neurologic tests, the deep tendon reflex test, and the straight leg raise test, revealed no specific findings...
