As metastatic disease is the most frequent pathology that results in incidentally discovered diffuse osteoblastic lesions, biopsy should be performed in case of doubt.

It is the fifth most common gastrointestinal malignancy and the most common biliary tract cancer. Early diagnosis remains difficult, because clinical symptoms are sparse and non-specific, often resulting in advanced stage disease at the time of diagnosis. The most common feature of gallbladder carcinoma on different imaging modalities is focal wall thickening, associated with a large eccentric tumor mass. In this case we report the imaging characteristics of gallbladder carcinoma on ultrasound, MDCT and 18F-FDG PET/CT.

It is a rare soft-tissue mass that can develop in any soft tissue. Most commonly it appears in the tongue (40%), the oral cavity or in the subcutaneous tissue. In rare occasions it is reported as a breast mass, mimicking a carcinoma. Not only clinically, but also on mammography, ultrasonography and macroscopically. Diagnosis can only be made on histology, emphasizing once again the importance of a thorough pre-operative multi-disciplinary assessment. We describe a case in which a woman presents herself with a palpable nodule in the breast in which clinical investigation, mammography and especially sonography indicated the presence of a malignancy. Only after we conducted a core biopsy for pre-operative histological investigation, we could make the diagnosis of a granular cell tumor, preventing an unnecessary mastectomy. The patient refused however local excision and was followed up with mammography and sonography.

Hepatic hemangiomas are congenital vascular malformations and are the most common benign tumours of the liver. Most cases are asymptomatic. Although they seldom rupture, it is important to diagnose them as their global mortality rate is high. An accurate diagnosis of a hemangioma as cause of a hemoperitoneum would result in correct clinical decision making and treatment.

Further imaging revealed diffuse calcifications within the mesentery and greater omentum. Amyloid deposition may mimic chronic granulomatous disorders and primary or secondary neoplastic conditions. Although definite diagnosis is made on histology, the radiologist should include amyloidosis in the differential diagnosis in the absence of a clinical history of neoplastic disorders or chronic infection, especially if extensive intra- lesional calcifications are seen. Ultrasound may be useful to target solid noncalcified areas in easily accessible extra- abdominal locations.

It develops through a congenital defect in the retrosternal area. Usually asymptomatic, this entity can lead to life-threatening complications such as incarceration, strangulation or volvulus of the herniated viscus. We hereby report a rare case of organoaxial gastric volvulus producing through the foramen of Morgagni in a 78-year-old woman. The full diagnosis was made by upper gastro-intestinal series and multidetector computed tomography (MDCT). The basic anatomy, physiopathology, diagnostic methods, complications and surgical treatment of Morgagni hernia are briefly reviewed.

They consist of abnormally large vascular cavities or sinusoid channels of varying size. The majority of cavernous malformations in the brain are small and do not always present with symptoms. A minority of large cavernous malformations, known as giant cavernous malformations (GCM), can cause neurological symptoms (such as headaches, focal neurologic deficits and seizures), which are probably related to hemorrhage and mass effect. GCM grow steadily in size over time, due to repetitive episodes of bleeding. The purpose of this paper is to document two case reports of patients with GCM, illustrate the radiological appearance, discuss the neurosurgical consequences, and to provide a literature analysis.

MATERIALS AND METHODS: Thirty-one asymptomatic subjects were examined by 2 musculoskeletal radiologists. The plantar fascia was evaluated for thickness, echogenicity, vascularity on power Doppler, rupture, fluid adjacent to the fascia, andcalcifications. RESULTS: The study included 14 men and 17 women (age, 17-79 years; mean, 45 years). The mean thickness of the plantar fascia in men was 3.7 mm (range 2.5-7 mm), and in women 3.5 mm (range, 1.7-5.1 mm). The thickness was greater than 4 mm in 4 men (bilateral in 2). The mean thickness of fascias thicker than 4 mm in men was 5.4 mm (range, 4.3-7 mm). The thickness was greater than 4 mm in 5 women ( bilateral in 4). The mean thickness of fascias thicker than 4 mm in women was 4.7 mm (range, 4.2-5.1 mm). There was no statistically significant difference between men and women and between both heels. Hypoechogenicity was observed in 3 men (bilateral in 2), and in 5 women (bilateral in 6). Hypervascularity, rupture, fluid adjacent to the fascia, and calcifications were not observed. CONCLUSION: A thickness greater than 4 mm and hypoechogenicity, are common in the plantar fascia of asymptomatic subjects. Findings that were not seen in asymptomatic subjects include a thickness greater than 7 mm, hypervascularity on power Doppler, rupture, fluid adjacent to the fascia, and calcifications.
