A 44-year-old male patient presented with suddenly occurring first time painless jaundice. The patient history included whitish colored stools but no fever or weight loss. Imaging diagnostics and blood analysis revealed a strong suspicion of pancreatic disease. Histological examination showed dense plasma and lymphocellular infiltration and areas of fibrosis of the pancreatic parenchyma and confirmed the diagnosis of autoimmune pancreatitis which was successfully treated with immunosuppressive drugs.

A 53-year-old female patient presented with sudden onset confusion and disorientation. Further neurological examination was unremarkable and the patient showed a complete recovery after several hours. A magnetic resonance imaging (MRI) examination performed 2 days later revealed a tiny focal lesion in the lateral hippocampus in the diffusion weighted images consistent with transient global amnesia.

Neuroradiology plays a key role in the diagnosis of brain tumors. Computed tomography (CT) and specially magnetic resonance imaging (MRI) allow accurate anatomic depiction of intracerebral lesions. The implementation of native and contrast studies allows the characterization of the various lesions encountered in the majority of cases. In this review the imaging aspects on CT and MRI of the most common primary intra-axial brain tumors will be discussed.

A 73-year-old woman presented with a swelling of the right sternoclavicular joint the size of a hens egg which had persisted for 2 years. After a corticosteroid injection 8 months previously the swelling was asymptomatic. ⋯ The constellation is indicative of Tietze syndrome, an inflammation of costochondral junctions of the ribs or chondrosternal joints. The treatment is usually directed at pain relief and benign conditions are often self-limiting.

Spinal epidural hematoma is an accumulation of blood in the potential space between the dura and bone. On unenhanced computed tomography epidural hemorrhage appears as a high-density spinal canal mass with variable cord compression. Magnetic resonance imaging is the modality of choice for evaluating spinal epidural hematoma and can demonstrate the extent of the hematoma and degree of cord compression. When treated surgically the outcome depends on the extent of preoperative neurological deficits and on the operative timing interval.
