A woman in her 60s developed acute onset headache, blurry vision and encephalopathy a few hours after rituximab infusion, given to treat granulomatosis with polyangiitis. CT scan showed oedema in the posterior circulation area suggesting the diagnosis of posterior reversible encephalopathy syndrome, and an MRI confirmed it. After being treated with aggressive blood pressure control and other supportive measures, her symptoms improved over 3–4 days. This case highlights the need for awareness and early recognition of this rare but serious adverse effect of rituximab. CT scan can be helpful in diagnosis (also to rule out bleeding), but the MRI provides the most accurate diagnosis.
A woman in her 70s with a history of chronic minocycline use presented with complaints of a non-tender posterior neck mass. A thyroid gland ultrasound showed a highly suspicious right thyroid nodule. A total thyroidectomy revealed darkened discolouration of the thyroid gland and tracheal cartilage. The pathology report showed dark brown granules representing melanin. Chronic minocycline usage is known to cause pigmentation of nails, teeth, bones and the thyroid gland. Our case highlights the importance of recognising that long-term use of minocycline can cause discolouration of the thyroid and tracheal cartilage. Current case studies do not show any adverse health effects associated with black thyroid and tracheal cartilage. For patients who are to undergo neck surgery, physicians need to be aware of this side effect, and that further intervention, such as surgical resection, may not be required.
To my mentors in all three departments, for listening to and encouraging my crazy ideas. Thank you for all the guidance, all the headaches, all the epiphanies. To my parents, who have given me everything. Thank you for your continuous support, even if you still have no idea what I'm actually doing. To Matt and Emiliano, for your incredible insight and expertise. Thank you for introducing me to this marvellous art. To the Wesleyan Rugby community, I am who I am because of who you all have made me. Last, but not least, to my friends, who are my family. I could not have done this without your love and support.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
