RATIONALE: Clear cell sarcoma of tendon and aponeurosis (CCSTA) or soft parts is a rare malignant melanin producing tumor entity that is derived from the neural crest cells originating from soft tissues displaying melanocytic differentiation. Diagnosis of CCSTA is difficult as it is dependent on age, size, location, necrosis, calcifications, cystic degeneration, and local to distant metastatic deposits. These tumors have very poor prognosis with a survival rate of 5-10 years because of local recurrence, early to late metastasis to lymph nodes, lungs, bones, and liver...

BACKGROUND: Congenital cholesteatomas (CC) arise from epithelial remnants around the petrous bone. They enlarge gradually causing progressive destruction and functional damage to the ear and surrounding structures. Because of their insidious course, most patients are misdiagnosed and present late with complications. METHODS: This is a retrospective study of 41 cases diagnosed as CC and followed up for 2 years. All patients underwent full audiological evaluation and a radiological study (CT, MRI)...

OBJECTIVE There is no definitive or consensus classification system for the jugular bulb position that can be uniformly communicated between a radiologist, neurootologist, and neurosurgeon. A high-riding jugular bulb (HRJB) has been variably defined as a jugular bulb that rises to or above the level of the basal turn of the cochlea, within 2 mm of the internal auditory canal (IAC), or to the level of the superior tympanic annulus. Overall, there is a seeming lack of consensus, especially when MRI and/or CT are used for jugular bulb evaluation without a dedicated imaging study of the venous anatomy such as digital subtraction angiography or CT or MR venography...

PURPOSE: In forensic clinical anatomy computed tomography (CT) is used in post-mortem radiological investigation as an objective nondestructive documentation of the body surface and of the interior of the body. This technique is applied also in paleopathology, in particular in mummy studies, with the aim of providing a permanent record of the mummy's features, investigating the embalming procedure employed and analyzing the extent of the preservation in detail. METHODS: For the Extraordinary Jubilee of Mercy, the mortal remains of Saint Leopold Mandic and Saint Pio da Pietralcina, as examples of Mercy known by everyone, have been brought to Rome in February 2016...

INTRODUCTION: HIV-positive children are possibly more prone to developing cholesteatoma. Chronic inflammation of the middle ear cleft may be more common in patients with HIV and this may predispose HIV-positive children to developing cholesteatoma. There are no studies that describe the radiological morphology of the middle ear cleft in HIV-positive compared to HIV-negative children with cholesteatoma. OBJECTIVES: Compare the radiological differences of the middle ear cleft in HIV-positive and HIV-negative children with cholesteatoma...
