ABSTRACT
Primary spinal cord glioblastoma multiforme (GBM) remains uncommon and typically affects males and patients during their fifth decade of life. Our case demonstrates a 77-year-old woman who initially presented with right arm paresthesia and limited range of motion and was subsequently diagnosed with primary spinal cord GBM. Our case illustrates an atypical and nonspecific neurological presentation highlighting that spinal cord GBM can have a more indolent course, unlike what current literature suggests. It also emphasizes the importance of considering a multimodal approach when managing atypical neurological symptoms and considering an early intervention, including magnetic resonance imaging, to rule out occult neoplasm in an appropriate clinical setting, thus preventing delay in the diagnosis. This case further emphasizes the role of molecular biomarkers of tumors, including isocitrate dehydrogenase mutation as well as methylguanine-DNA methyltransferase promoter methylation status, that can independently guide and affect the treatment outcomes in this patient population.
ABSTRACT
Oxalate nephropathy is a rare pathology that can be difficult to diagnose. It results from calcium oxalate crystals that are deposited in the renal interstitium or renal tubules. Once the deposition ensues, a multitude of complications can occur, including renal failure. One etiology for oxalate nephropathy is a lack of biliary acid. The diagnosis of oxalate nephropathy is typically based on visualization of oxalate crystals in the renal tubules on biopsy, and treatment based on the etiology can range from simple removal of the offending agent or a change in diet to liver/kidney transplant in the setting of primary hyperoxaluria. This report discusses a case of severe oxalate nephropathy related to long-term cholecystostomy tube placement resulting in a deficiency of biliary acid.
ABSTRACT
Statin-induced necrotizing myositis is a rare subtype of idiopathic inflammatory myopathies due to the production of an antibody to the 200/100 kDA protein complex which was subsequently found to be directed against 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR). Similar to other auto-immune necrotizing myopathies, the disease is characterized by proximal muscle weakness, significant serum creatine kinase elevations, and histological evidence of necrosis of myocytes. However, there is often little to no infiltration of inflammatory cells noted on muscle biopsy. As the name implies, this subtype of idiopathic inflammatory myopathy is provoked by statin use which may be a helpful finding during the history-taking process when developing a differential diagnosis. Below, we discuss a case of a 52-year-old female with delayed-onset immune-mediated necrotizing myopathy secondary to statin use.
