Assessment of bone marrow fat by 3-Tesla magnetic resonance spectroscopy in patients with chronic kidney disease.

Background: Proton magnetic resonance spectroscopy (H MRS) is an imaging method for quantification of bone marrow fat. It has been used for evaluation of bone marrow changes in patients with chronic disorders, such as chronic kidney disease (CKD). In these patients, there is a high turnover state, with an excessive amount of non-mineralized component of bone, leading to skeletal fragility and subsequent increased fracture risk.

A rare case of isolated gallbladder rupture following blunt abdominal trauma.

Isolated gallbladder rupture are rare injuries. We present a case of gallbladder traumatic rupture in a 47-year-old patient involved in a motor vehicle collision, that presented abdominal pain with maximal intensity in the right upper quadrant.CT is the imaging technique of choice to diagnosis this entity, however the final diagnosis of gallbladder rupture is confirmed with laparoscopy.

A rare case of siliconomas resulting from free silicone injections in breast tissue.

One of the most common complications of free silicone injection at multiple sites is its leakage and more rarely its migration through the lymphatic system with a resulting local inflammatory reaction of granulomatous type, known as "siliconoma". This report describes the case of a young woman who came to our attention for bilateral mastodynia and palpable tumefactions in breast and gluteal region, a few years after percutaneous injections of free liquid silicone for breast augmentation.

The promising role of DECT in the diagnosis of Osteitis Condensans Ilii: a case report.

Osteitis condensans ilii (OCI) is a noninflammatory condition of no clear etiology, cause of axial low back pain. It is characterized by sclerotic bone lesions at the iliac region of the sacroiliac joints. The diagnosis is based on radiological findings and the exclusion of other conditions associated with back pain.

Two rare cases of pituitary apoplexy in adult females: a tricky diagnosis.

We reported two cases of women who suffered from a rare case of pituitary apoplexy, rare and potentially fatal clinical condition due to a hemorrhagic infarction of the pituitary gland due to a pre-existing macroadenoma. The onset of symptoms is often insidious and includes generic symptoms such as headache, vomiting, and visual disturbances. In this case report we discuss the typical CT and MRI imaging features of this rare clinical condition in order to help radiologists in the timely diagnosis for a more rapid and correct diagnostic framing.

Fragility Score: a REMS-based indicator for the prediction of incident fragility fractures at 5 years.

Background: Accurate estimation of the imminent fragility fracture risk currently represents a challenging task. The novel Fragility Score (FS) parameter, obtained during a Radiofrequency Echographic Multi Spectrometry (REMS) scan of lumbar or femoral regions, has been developed for the non-ionizing estimation of skeletal fragility.

Aims: The aim of this study was to assess the performance of FS in the early identification of patients at risk for incident fragility fractures with respect to bone mineral density (BMD) measurements.

Mesentero-axial gastric volvulus in an old woman: a case report of a diagnostic challenge.

Gastric volvulus is a rare conditiom defined as an abnormal rotation of the stomach around itself. Acute gastric volvulus is a surgical emergency because it is a life-threatening condition, but its non-specific symptoms make diagnosis difficult. There are two types of gastric volvulus: organoaxial and mesentero-axial.

Advance MR evaluation of synchronous multifocal osteosarcoma with pathologic fracture.

Objective: Synchronous multifocal osteosarcoma is a rare condition in which the osteosarcoma presents with multiple bone lesions at the time of diagnosis, usually without any visceral metastases. The first case was described in early 1930s by Silverman. To report a case of synchronous multifocal osteosarcoma in adolescent with pathologic fracture.

Postmenopausal osteoporosis: current status of bone densitometry.

Osteoporosis is the most common of all metabolic bone disorders characterized by loss of bone strength, due to modifications in bone turnover. It leads to bone fragility and increased fracture risk. Because of the increasing aging of the world population, the number of people affected by osteoporosis is continuously increasing.

A rare sacral localization of giant cell tumor in a young adult female: a case report.

We reported the case of a 42-years-old woman who suffered from a giant cell tumor of sacrum. Although the giant cell tumor primarily affects the long bones, especially those of the knee joint, it can rarely affect the axial skeleton and the sacrum. The onset of symptoms is generally insidious and may include locoregional pain and swelling as well as movement deficits if nerve roots are involved at this level.

Metabolic Bone Diseases in the Pediatric Population.

Bone plays an important role in regulating mineral balance in response to physiologic needs. In addition, bone is subject to a continuous remodeling process to maintain healthy bone mass and growth. Metabolic bone diseases are a heterogeneous group of diseases caused by abnormalities of bone mass, mineral structure homeostasis, bone turnover, or bone growth.

Hoffa's fat pad thickness: a measurement method with sagittal MRI sequences.

Background: Hoffa's fat pad is a structure located within the fibrous joint capsule of the knee joint, but outside the synovial cavity. It plays an important biomechanical and metabolic role in knee joint, reducing the impact of forces generated by loading and producing cytokines. Changes in its size can induce modifications in the knee homeostasis.
