RESUMEN
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. Cholecystectomy is the definitive treatment.

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.

BACKGROUND AND AIM: Prostatic utricle cyst is an embryological remnant of the Muller duct system, resulting from an incomplete regression of these structures during embryological development. Most of the time such congenital alteration is asymptomatic, but may sometimes present with various signs and symptoms, from urinary tract infections to episodes of haematospermia in a small percentage of cases. METHODS: We reported the case of a 42-years-old man who suffered from recurrent episodes of haematospermia for about 20 years; the instrumental examinations, first of all TRUS and then MRI evaluation, demonstrated the presence of a cystic formation, located in the posterior median site of the prostate closely to the prostatic urethra. RESULTS: The cytological examination on the liquid taken by transperineal US-guided fine-needle aspiration, confirmed the presence of seminal fluid and normal prostatic tissue consistent with the diagnostic hypothesis of prostatic utricle cyst. CONCLUSIONS: It's important to recognize the imaging characteristics of the prostatic utricle cyst since it may be one of the possible benign causes of hematospermia in the young adult subject.

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. In this case report we discuss on the radiographic imaging, computed tomography and magnetic resonance imaging features of this type of tumor in an unusual location of the disease.

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. In pediatrics, several significant advances have been made in recent years in the diagnosis of metabolic bone diseases (e.g., osteogenesis imperfecta, hyperparathyroidism, rickets, renal osteodystrophy, pediatric osteoporosis, and osteopetrosis). Imaging is fundamental in the diagnosis of these pathologies.

Body composition assessment (BCA) represents a valid instrument to evaluate nutritional status through the quantification of lean and fat tissue, in healthy subjects and sick patients. According to the clinical indication, body composition (BC) can be assessed by different modalities. To better analyze radiation risks for patients involved, BCA procedures can be divided into two main groups: the first based on the use of ionizing radiation (IR), involving dual energy X-ray absorptiometry (DXA) and computed tomography (CT), and others based on non-ionizing radiation (NIR) [magnetic resonance imaging (MRI)]. Ultrasound (US) techniques using mechanical waves represent a separate group. The purpose of our study was to analyze publications about IR and NIR effects in order to make physicians aware about the risks for patients undergoing medical procedures to assess BCA providing to guide them towards choosing the most suitable method. To this end we reported the biological effects of IR and NIR and their associated risks, with a special regard to the excess risk of death from radio-induced cancer. Furthermore, we reported and compared doses obtained from different IR techniques, giving practical indications on the optimization process. We also summarized current recommendations and limits for techniques employing NIR and US. The authors conclude that IR imaging procedures carry relatively small individual risks that are usually justified by the medical need of patients, especially when the optimization principle is applied. As regards NIR imaging procedures, a few studies have been conducted on interactions between electromagnetic fields involved in MR exam and biological tissue. To date, no clear link exists between MRI or associated magnetic and pulsed radio frequency (RF) fields and subsequent health risks, whereas acute effects such as tissue burns and phosphenes are well-known; as regards the DNA damage and the capability of NIR to break chemical bonds, they are not yet robustly demonstrated. MRI is thus considered to be very safe for BCA as well US procedures.
