This is a case report on a young patient with severe osteoporosis that was initially revealed when she presented with polyarthralgia during her second pregnancy. Postpartum, the pain increased and her X-ray did not show any abnormalities. A bone scintigraphy was performed. It indicated an inflammatory rheumatic disorder. Six months after partum, an investigation of right coxalgia revealed a spontaneous basicervical fracture. Given the persistent polyarthralgia, the patient underwent a new scintigraphy, which revealed areas of what looked to be old rib and L1 fractures. A subsequent full body magnetic resonance imaging (MRI) scan revealed signal abnormalities that could indicate multiple lower limb bone fractures. Despite exhaustive biological, radiological, and histological testing, no secondary cause for the osteoporosis was found. The patient was started on teriparatide. We finally concluded that, despite the atypical presentation, the patient was suffering from postpregnancy osteoporosis. It is possible that the frequency of occurrence of this still poorly understood disease is underestimated.

Prescribing Information

This is an update to the 2010 article published in Hospital Pharmacy on safety concerns involving transdermal patches and magnetic resonance imaging (MRI). Since publication of the original article, new brand and generic transdermal medications have become available and notable changes regarding the presence or absence of metallic content among existing transdermal formulations occurred. To update the tables within the article, Food and Drug Administration (FDA)-approved transdermal medications through October 2020 were researched in order to determine metallic content and procedures for reapplication after MRI, if applicable. Readers should consult the prescribing information or manufacturer for the most current information on use of transdermal medications in the MRI setting. Of note, manufacturers have not evaluated the use of transdermal products while patients undergo a MRI scan.

AbstractThe Kernohan-Woltman notch phenomenon is a paradoxical neurological manifestation consisting of a motor deficit ipsilateral to a primary brain injury. It has been observed in patients with brain tumors and with supratentorial hematomas. It is considered a false localizing neurological sign. Magnetic resonance imaging (MRI) scan has been the test of choice. The recognition of this phenomenon is important to prevent a surgical procedure on the opposite side of the lesion. The present case report describes a case of chronic subdural hematoma with a probable finding of the Kernohan-Woltman phenomenon, and it discusses its pathophysiology, imaging findings, treatment, and prognosis.

Acoustic Emission Analysis

The knee joint, being the largest joint in the human body, is responsible for a great percentage of leg movements. The diagnosis of the state of knee joints is usually based on X-ray scan, ultrasound imaging, computerized tomography (CT), magnetic resonance imaging (MRI), or arthroscopy. In this study, we aimed to create an inexpensive, portable device for recording the sound produced by the knee joint, and a dedicated application for its analysis. During the study, we examined fourteen volunteers of different ages, including those who had a knee injury. The device effectively enables the recording of the sounds produced by the knee joint, and the spectral analysis used in the application proved its reliability in evaluating the knee joint condition.

Meningiomas are known to be more common in females than males. They are also known in rare cases to grow in size during pregnancy, which can complicate its management. We describe a 31-year-old Caucasian woman who presented with blurring of her vision and diplopia during the third trimester of her pregnancy. Magnetic resonance imaging (MRI) showed a small left cavernous sinus meningioma. The patient was treated conservatively until her uncomplicated delivery. A postpartum MRI scan showed complete regression of the suspected meningioma. Currently the patient is contemplating a further pregnancy.

The goal of this work was to develop a shape memory polymer (SMP) foam with visibility under both X-ray and magnetic resonance imaging (MRI) modalities. A porous polymeric material with these properties is desirable in medical device development for applications requiring thermoresponsive tissue scaffolds with clinical imaging capabilities. Dual modality visibility was achieved by chemically incorporating monomers with X-ray visible iodine-motifs and MRI visible monomers with gadolinium content. Physical and thermomechanical characterization showed the effect of increased gadopentetic acid (GPA) on shape memory behavior. Multiple compositions showed brightening effects in pilot, T1-weighted MR imaging. There was a correlation between the polymeric density and X-ray visibility on expanded and compressed SMP foams. Additionally, extractions and indirect cytocompatibility studies were performed to address toxicity concerns of gadolinium-based contrast agents (GBCAs). This material platform has the potential to be used in a variety of medical devices.

Mri Changes

We report a case of complete palmar dislocation of the lunate in a rheumatoid patient. X-rays showed a normal bone structure of the lunate without sclerosis or collapse and on MRI an almost normal signal intensity was found. The lunate was removed. Histological examination showed complete necrosis of both marrow and bone cells, and tetracycline labelling showed no fluorescence. This case illustrates that neither X-ray nor magnetic resonance imaging (MRI) can detect complete bone necrosis. When X-ray or MRI changes do occur, these are indications of cellular events following some degree of spontaneous revascularization.
