Lipoma arborescens (LA) is a rare non-neoplastic intra-articular lesion that most commonly affects the knee joint, especially the suprapatellar bursa. It rarely affects the elbow joint. There are a few reports of involvement of the bicipital radial bursa. We report a case of LA, with characteristic MRI features, affecting the elbow joint in a young male.

The purpose of this study was to evaluate the role of diffusion weighted-magnetic resonance imaging (DW-MRI) in the examination and classification of brain tumors, namely, glioma and meningioma. Our hypothesis was that as signal intensity variations on diffusion weighted (DW) images depend on histology and cellularity of the tumor, analysing the signal intensity characteristics on DW images may allow differentiating between the tumor types. Towards this end the signal intensity variations on DW images of the entire tumor volume data of 20 subjects with glioma and 12 subjects with meningioma were investigated and quantified using signal intensity gradient (SIG) parameter. The relative increase in the SIG values (RSIG) for the subjects with glioma and meningioma was in the range of 10.08–28.36 times and 5.60–9.86 times, respectively, compared to their corresponding SIG values on the contralateral hemisphere. The RSIG values were significantly different between the subjects with glioma and meningioma (P < 0.01), with no overlap between RSIG values across the two tumors. The results indicate that the quantitative changes in the RSIG values could be applied in the differential diagnosis of glioma and meningioma, and their adoption in clinical diagnosis and treatment could be helpful and informative.

Diffusion Weighted Magnetic Resonance Imaging (DW-MRI) has become an established part of neuroimaging and is used to diagnose and characterize several neurologic disorders. Intracerebral Haemorrhage (ICH) is a severe medical condition, which may develop quickly into a life-threatening situation, and thereby requires prompt medical attention. Early and reliable identification of the age of haemorrhage is essential when choosing the correct treatment, and estimating patient's diagnosis and outcome. Diffusion Weighted (DW) images presents a variation in the image signal intensity characteristics relative to the different stages of ICH. In the present paper, an effort is made to document the variation in the image signal intensity characteristics of ICH at evolving stages, for 30 subjects, using High Frequency Power (HFP) parameter. Results showed that the difference in the HFP values on DW images for the subjects with ICH compared to their contralateral normal hemisphere, were highly significant (p < 0.

Ryle's tube insertion is a simple routine clinical procedure usually without any complications. Minor complications like injury to nasal or oral cavity and epistaxis may occur with the insertion of Ryle's tube. However it can lead to occasional unexpected life threatening complications such as esophageal or pulmonary perforation, pneumothorax, intravascular penetration or entry into the cranial cavity. Herein, we report a case of supra-glottic edema due to Ryle's tube insertion leading to stridor necessitating tracheostomy. We recommend that the Ryle's tube should be inserted by adequately trained personnel and its correct position should always be confirmed.
