Acute transient contrast-induced neurologic deficit is an uncommon condition triggered by the administration of intra-arterial contrast during angiography. It can present with encephalopathy, cortical blindness, seizures, or focal deficits. This report describes a patient who presented with severe neurologic deficits after percutaneous coronary intervention, with complete symptom resolution within 72 hours.

Bilateral medial medullary infarction (BMMI) is a rare stroke subtype that accounts for less than 1% of acute strokes. Common manifestations of this stroke include quadriparesis, bilateral hypoglossal palsy, bilateral sensory loss, and respiratory failure. We present the case of a 39-year-old male with deafness and mutism who was brought to the emergency department due to acute onset of altered mental status and generalized weakness, further decompensated, and was lately diagnosed with bilateral medial medullary infarction. This case hopes to illustrate a differential diagnosis to be considered and promptly managed when a patient presents with altered mental status and quadriparesis, especially in the acute setting where tissue plasminogen activator (tPA) can still be given.
Refeeding syndrome is the potentially fatal shift in fluids and electrolytes that may occur in malnourished patients after receiving artificial refeeding. Its hallmark feature is hypophosphatemia, although other electrolytes might also be affected. Fanconi syndrome is a generalized dysfunction of the proximal tubule characterized by proximal renal tubular acidosis (RTA), phosphaturia, glycosuria, aminoaciduria, and proteinuria. The etiology of Fanconi syndrome can be either acquired or inherited, and drugs, among them tenofovir, are a common acquired cause of this disease. We present the case of a patient with AIDS and polysubstance abuse who was admitted due to pneumonia, completed treatment, was then started on antiretroviral medication (ART) that included tenofovir alafenamide (TAF) and began presenting severe episodes of hypophosphatemia along with other electrolyte imbalances, leading the workup denoted in the case, severe complications and finally to the patient's demise. Most cases of tenofovir-related Fanconi syndrome are related to tenofovir disoproxil fumarate, but very few cases have been reported with TAF. Our case highlights this rare complication of therapy with TAF and how artificial feeding can contribute to severe electrolyte abnormalities and worsen outcomes.
Subcapsular hematoma (SRH) or perirenal hematoma (PRH) can be seen after trauma, interventional radiological procedures, urological procedures, anticoagulant medications, coagulation disorders, infections, and spontaneously in some patients. Within the urological procedures, PRH can occur after percutaneous nephrolithotomy and extracorporeal shortwave lithotripsy but has only been reported a few times after cystoscopy/ureteroscopy. Here, we present the case of PRH as a complication from cystoscopy with retrograde pyelography in a patient with underlying chronic kidney disease (CKD) and an extensive surgical history for nephrolithiasis. In addition to this, our patient had a further complication of sepsis by Candida albicans, of which the source is proven to be urinary, and it appears that the fungemia was triggered during the procedure as well. The diagnosis was confirmed by abdominal computed tomography (CT), and PRH was proven to resolve with conservative management on repeat imaging months later.
