Objective To determine diagnostic ability of brain magnetic resonance imaging (MRI) in detection of idiopathic intracranial hypertension (IIH). Method This descriptive observational study was conducted in radiology department from Jan. 2018 to Jan. 2021, evaluating MR imaging data of all adult patients (n=107) with clinical presentations of headaches. Patients with space occupying lesions, obstructive hydrocephalus and cerebral venous sinus thrombosis were excluded. Presence of all three brain MRI findings of (i) an empty sella (with or without sellar enlargement), (ii) tortuosity of optic nerves (with or without perioptic CSF prominence) and (iii) non-dilated (or slit-like) ventricles was considered positive for IIH. Imaging was reviewed by two neuroradiologists and consensus reporting was made. Findings of IIH were confirmed by presence of high lumbar opening cerebrospinal fluid (CSF) pressure or symptomatic response towards specific medical treatment. Outcomes of brain MRIs were presented on a 2x2 contingency table. Results Sensitivity, and specificity of routine brain MRI findings in detection of IIH were calculated as 76.4% [95% confidence interval (CI), 64.62-85.91%], and 84.6% (95% CI, 69.47-94.14%) respectively. Conclusion: IIH is a known cause of headache. Detection of all three findings of empty sella, tortuosity of optic nerves and non-dilated ventricles on routine brain MRI can predict IIH with greater sensitivity and specificity.

Lipoma arborescens is a rare, mainly intra-articular lesion characterized by diffuse replacement of subsynovial tissue by mature fat cells. It can be primary or secondary. The secondary type of lipoma arborescens is the more common. It is associated with an underlying chronic joint inflammation and irritation and is usually affecting the elderly patients. In this paper, we report an unusual case of Lipoma arborescens secondary to gouty arthritis affecting the left knee of a young male associated with a giant popliteal cyst and degenerative changes. An open synovectomy and excision of the popliteal cyst was performed.&nbsp
