Non-Hodgkin Lymphoma Mimicking Vestibular Schwannoma.

Progressive unilateral hearing loss and an MRI are usually enough to diagnose vestibular schwannoma (VS). We were consulted by a 45-year-old man with otalgia and left-sided hearing loss as well as ipsilateral facial paralysis that had begun two weeks prior. Due to a possible atypical presentation of VS, an MRI was ordered, which revealed an intracanalicular lesion occupying the left cerebellopontine angle cistern.

The Hook Effect: A Case Study of a Giant Invasive Prolactinoma With Falsely Low Serum Prolactin.

Prolactinomas are benign pituitary tumors also known as prolactin-secreting adenomas (PSA). These tumors cause excessive secretion of prolactin (hyperprolactinemia), a hormone responsible for lactation. Diagnosing hyperprolactinemia relies on measuring prolactin levels in the blood, and elevated serum levels of prolactin are typically indicative of prolactinoma.

Wernicke-Korsakoff Syndrome as a Consequence of Hyperemesis Gravidarum: A Case Report.

Wernicke-Korsakoff syndrome (WKS) is caused by severe thiamine (vitamin B1) deficiency and can lead to chronic deficits. In this case, a 22-year-old pregnant patient at 10 1/7 weeks of gestation presented to the emergency department with malaise, asthenia, headache, weakness, vomiting, and weight loss of 12 kg. Pancreatitis and hepatic steatosis were considered but ruled out, and cholecystolithiasis was confirmed by ultrasound.
