We report a case of Prader-Willi syndrome (PWS) complicated with juvenile stroke. The patient is a 19-year-old man with right hemiplegia, who has had a history of non-insulin-dependent diabetes mellitus (NIDDM) for ten years. The diagnosis of PWS was confirmed genetically by the method of fluorescence in situ hybridization which showed the deletion of chromosome 15. His brain MRI revealed abnormal signal intensities in the left basal ganglia and around the right trigone of the lateral ventricle. Angiographic examination showed occlusions of bilateral proximal middle cerebral arteries with basal moyamoya vessels. The left vertebral artery was also occluded at its origin. Only a few cases of PWS complicated with stroke have been reported before and, to date, there has been no case with arterial occlusion similar to our case. Though the cause of these arterial occlusions is unknown, it may be related to arteriosclerosis following NIDDM.

A 58 year old patient with dementia, oral dyskinesia, and diabetes mellitus is described. He had an undetectable concentration of serum caeruloplasmin, as an autosomal recessive trait. Brain MRI disclosed a pronounced hypointensity in the bilateral putamina, caudate, and dentate nuclei on both T1 and T2 weighted images. Pathological findings were mainly in those regions of the brain and consisted of neuronal cell loss with gliosis, heavy iron deposition, and spheroids. Visceral organs also had iron deposition, especially severe in the liver and pancreas. The present patient and other recorded cases constitute a clinicopathological entity of hereditary caeruloplasmin deficiency, different from Wilson's disease.

A 64-year-old woman with diabetes mellitus was admitted to our hospital with left hemiparesis of sudden onset. A brain MRI demonstrated a cerebral infarction in the ventral part of the right lower pons. When left hemiparesis worsened, she had dislocation of the temporo-mandibular joints repeatedly. Then, her lower jaw deviated to the right when she opened her mouth. Also, there was decreased contraction of the right masseter when she clenched her teeth. These findings suggest that there was trigeminal motor paralysis on the right side resulting from involvement of the intrapontine trigeminal motor nerve. She has no history of dislocation of the temporo-mandibular joints. An X-ray film showed that the temporo-mandibular joints were intact. Thus, it is possible that deviation of the lower jaw was the cause of this dislocation. We suspect that dislocation of the temporo-mandibular joints may occur as a complication of unilateral trigeminal motor paralysis. This has not been reported to our knowledge.

The blood-ocular barrier (BOB) shares similar neuroepithelial origin, microanatomy and functions with the blood-brain barrier. There are many natural (e. g. diabetes, hypertension) or iatrogenic (chemotherapy, retinal photocoagulation) conditions which can cause a BOB breakdown, resulting in visual acuity impairment or loss. The authors examined 42 patients affected by BOB damage in different pathological conditions. All patients previously underwent a conventional fluoroangiographic (FA) study. Nine patients with normal FA exam were evaluated also. Despite normal MRI findings immediately after Gd-DTPA injection, contrast leakage into the vitreous body or into the aqueous fluid was demonstrated in delayed scans (40-50 min after contrast administration), proving the existence of a BOB damage (sensitively 94 %). Although FA exam remains the choice modality in BOB breakdown demonstration, we propose MRI as a useful diagnostic tool when optic media opacity (cataract, haemovitreous, intraocular silicon oil) occurs, preventing direct retinal fundus imaging and/or an early screening tool.

Diabetic muscle infarction (DMI) is a rare complication of diabetes mellitus occurring in patients with poorly controlled insulin-dependent diabetes. In previous reports, the diagnosis of this condition was based on the pathologic studies, although MRI examinations were performed in a few patients as part of the diagnostic work-up. In this report, we describe two additional cases of DMI where the diagnosis was based on the MRI findings in conjunction with the clinical picture and laboratory studies. The patients usually present with thigh or calf pain and swelling, are afebrile, and have normal white blood cell count. MRI examination typically shows diffuse swelling and increased signal intensity on T2-weighted images in the affected muscles, with no focal fluid collections. In the proper clinical setting, these findings are diagnostic of DMI and patients should be spared unnecessary invasive diagnostic examinations such as lower extremity venograms and biopsies.

More than thirty types of tumors in the sellar region can mimic pituitary adenoma on, magnetic resonance imaging. When they exist, clinical manifestations are not necessarily highly contributive to diagnosis. Headache, visual impairment, signs of antepituitary insufficiency or possible dysmenorrhea with galactorrhea attributed to hyperprolactinemia due to compression of the dopaminergic axis are not specific and may be misleading. Clinical signs of diabetes insipidis and polyphagia are however suggestive of non-pituitary tumors. Consequently, high-resolution imaging (MRI) and sometimes particular diagnostic circumstances (post partum for hypophysitis for example, or breast cancer for metastasis) orient the diagnosis. More rarely tumor enlargement, for example in certain germ cell tumors, provides a clue.

Despite modern medical advances, the morbidity and mortality rates associated with spinal epidural abscess remain significant, and the diagnosis is elusive. The incidence of spinal epidural abscess is approximately one to two cases per 10,000 among all patients admitted to hospitals. The symptoms of spinal epidural abscess are varied but include lower back pain, fever, local tenderness and neurological deficit especially in such high risk groups as patients with diabetes, intravenous drug abuse, chronic renal failure, alcoholism, liver disease and immunocompromization. Accumulation of data is difficult in that many physicians will never see a case during their careers. Herein, we present a case with lower back pain associated with both lower legs weakness. His abdomenon CT revealed retroperitonium and right perirenal abscess. External drainage as well as antibiotic treatment was done immediately. However, the lower legs weakness became severe and a lumbar spine MRI revealed T11-L4 epidural abscesses and L2-3 intervertebral space pus formation. Then, the patient was transfered to our Neurosurgical Ward for further treatment. His postoperative condition improved in both lower legs. This case report is to enhance the recognition and treatment of spinal epidural abscess, a rare affliction.

Although nuclear magnetic resonance (NMR) is well-established as a routine clinical imaging technique (magnetic resonance imaging or MRI), its application as a tool for metabolic investigations in humans is much less widespread in the medical community. To date, very few laboratories have combined the scientific interest, technical expertise (especially in vivo NMR spectroscopy), and facilities required to perform meaningful NMR studies of human metabolism. Among the few published reports of studies using in vivo NMR spectroscopy, diabetes mellitus, or more generally the physiology and pathophysiology of glucose homeostasis, is the dominant topic. This situation is related to the historical role of the Yale MR Center (R.G. Shulman, D.L. Rothman) in the development of in vivo NMR, and to the collaboration of NMR methodologists with the Endocrinology Section of the Yale Medical School (G.I. Shulman). Thus, in the field of diabetes and metabolism, in vivo NMR has already contributed significantly to increasing our understanding of basic physiology as well as of pathophysiological mechanisms. This "practical research note" first describes the basic principles of in vivo NMR and provides practical information about the use of this technique in metabolic investigations. The metabolic parameters accessible through in vivo NMR are then reviewed and illustrated by a few examples from the literature.

Streptococcus agalactiae is a well-recognized cause of neonatal sepsis and meningitis. In adults, infections by S. agalactiae are rare. We report an adult case of lung abscess and pyogenic spondylitis caused by S. agalactiae. A 51-year-old male was admitted to our hospital because of an abnormal shadow in the chest and lumbago on May 25, 1995. He was diagnosed as lung abscess from the chest roentgenogram and CT scan and the subcutaneous pus was aspirated. The pus culture was only positive for S. agalactiae. He was treated with IPM/CS 1 g/day and CLDM 1.2 g/day and the abscess was drained. MRI showed his lumbago was caused by pyogenic spondylitis. The underlying disease of this case was diabetes mellitus. He recovered from the infections with in about 10 weeks of antibiotic treatment.

A case of pituitary apoplexy occurring after Gd-DTPA-administration for contrast enhanced MRI in a patient with an hGH-producing macro-adenoma is presented. Within days the initially increased hGH level fell to the normal range, the oral glucose tolerance test (OGTT) showed a normal suppression of hGH and complete anterior pituitary insufficiency developed. At this time repeated MRI suggested a haemorrhagic infarction of the macro-adenoma. Fourteen months later re-examination confirmed spontaneous cure of the acromegaly, improvement of adenopituitary function and shrinkage of the sellar content. The causal linkage between the pituitary adenoma apoplexy and Gd-DTPA-administration is unclear. It might be due to contrast induced blood pressure and endothelial permeability changes, possibly promoted by pre-existing diabetes mellitus associated vasculopathy.
