Abstract Magnetic resonance imaging (MRI) is the modern gold standard for the noninvasive evaluation of the cirrhotic liver. The combination of arterial phase hyperenhancement and delayed wash-out allows a definitive diagnosis of hepatocellular carcinoma (HCC) in patients with liver cirrhosis or chronic liver disease, without the requirement for confirmatory biopsy. That pattern is highly specific and has been endorsed in Western and Asian diagnostic guidelines. However, the sensitivity of the combination is relatively low for small HCCs. In this two-part review paper, we will address MRI of the cirrhotic liver. In this first part, we provide a brief background on liver cirrhosis and HCC, followed by descriptions of imaging surveillance of liver cirrhosis and the diagnostic performance of the different imaging modalities used in clinical settings. We then describe some of the requirements for the basic MRI technique, as well as the standard MRI protocol, and provide a detailed description of the appearance of various types of hepatocellular nodules encountered in the setting of the carcinogenic pathway in the cirrhotic liver, ranging from regenerative nodules to HCC.

Cerebellopontine angle extraaxial glioblastoma (GBM) is extremely rare at any age but especially in children. We reported a case of 14-year-old girl, who presented with nausea, vomiting and ataxia. She was evaluated with computed tomography (CT) and magnetic resonance imaging (MRI). Imaging demonstrated irregular ring enhancing right CP angle mass. The atypical findings of irregular ring enhancement, CP angle location and presentation in childhood, combine to make the prospective diagnosis of GBM a difficult one. This combination of findings has been reported very rarely.

Trivial Trauma is one of the causes of avascular necrosis of the femoral head. Even trivial trauma can cause loss of blood supply to the femoral head and results in ischemia and aseptic necrosis. A 68 year old male patient came with 2 month history of left hip pain. X-ray pelvis (fig-1) with both hips which was taken immediately after the trauma, showed no significant bony abnormality and patient was managed conservatively with analgesics. Patient had persisting pain for 2 months which increased in severity and patient developed difficulty walking. Therefore a Magnetic Resonance Imaging (MRI) L hip (fig-2) was done and which showed avascular necrosis grade III of left femoral head. Total hip replacement was then carried out for the patient and patient improved symptomatically. Earlier MRI imaging following trauma could have resulted in early diagnosis and intervention to prevent progression of the disease and salvage the femoral head.
