In this serial MRI study a 24 year old man presenting anterior spinal artery syndrome was examined. In the acute stage, spin echo sequences showed an enlarged cervical cord on a T1 weighted image and high signal intensity in the enlarged portion of the cord on a T2 weighted image. The findings were interpreted as oedema in the grey and white matter subsequent to ischaemia. In the chronic stage,...

We present a case of a solitary neurofibroma of the floor of the mouth protruding into the submandibular region. A 51-year-old female presented with a 2-year history of swelling of the floor of the mouth. MRI revealed that the mass measuring 50 × 70 mm showed a homogenous, low signal intensity on a T1-weighted image and high signal intensity on a T2-weighted image. The tumor was completely remo...

Reliable identification of the subthalamic nucleus (STN) is a critical step in deep brain stimulation for Parkinson disease but difficult on T1-weighted stereotactic MR imaging. By simultaneous imaging of multiple gradient echoes, susceptibility contrast is added to conventional T1-weighted high-resolution MR image. Thus, the visibility of the STN is enhanced on a second co-localized dataset by...

Abstract Background Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magne...

BACKGROUND Magnetic resonance (MR) signal changes suggestive of cerebral venous thrombosis (CVT) on T1- and T2-weighted images may be subtle and their identification requires a high degree of suspicion. Magnetic resonance venography remains essential for definitive diagnosis. Recent reports have shown that T2(*)-weighted MR sequence is more sensitive than T1-weighted, T2-weighted, and fluid-att...

A 26 year-old girl, previously healthy, admitted for progressive weakness of both lower limbs, with permanent paresthaesia evolving for 6 months. Clinical examination found spastic paraparesis with proprioceptive ataxia. The MRI showed bilateral and symmetrical lesions in the cervical spinal cord. Lesions were T1isointense and T2 hyperintense, located on both lateral and posterior funiculus wit...

INTRODUCTION Cavernous hemangiomas are rare benign bone tumors and those at the level of the cranial bones are even rarer. CASE PRESENTATION A 50-year-old woman of Italian ethnicity presented with a frontal mass. A computed tomography scan showed an osteolytic lesion and a magnetic resonance imaging scan revealed a hypointense lesion on the T1-weighted image and a hyperintense lesion on the T...
