Here's a challenging case of a disease first described in 1972.
A 30 year old previously healthy woman presents with a low grade fever and fatigue for a week. Physical exam shows posterior cervical lymphadenopathy localized to one side and the rash shown above. The lymph nodes are 1-2cm in diameter, firm, smooth, discrete, and mobile. Labs show leukopenia and an elevated ESR. The following tests are negative: ANA, RF, EBV, CMV, HIV, and toxoplasmosis. She has no cat contact and has not been scratched (I knew you were thinking it). A biopsy of a lymph node is shown below.
Challenge: Luckily, this diagnosis is benign and resolves after 1-4 months. What is it?

A husband and wife come to you for an infertility work-up. They have two healthy children already (and parentage is confirmed) and would like to have a third child, but have been trying for a year and been unsuccessful. The husband says, "I think it all happened after I got this infection. You see, a year ago, I had a fever to 40 degrees, severe testicular pain, and a rash on my scrotum." On exam, you note testicular atrophy.
Challenge: What happened?

Hello! Again, I apologize for the delay in cases; things have been awfully busy and I simply didn't have time to write. Here's a case I saw this week though, and I think the next case will probably be next Monday.
Thanks for understanding, and I appreciate your following along,
A 55 year old hypertensive smoker presents with an abrupt onset 10/10 headache, confusion, and vomiting. His main concern, however, is his vision; he has trouble seeing. A dilated eye exam is shown above. Panel A shows the right fundus, panel B the left fundus, panel C a week after laser treatment, and panel D two weeks after treatment. A non-contrast CT head from the ED is shown below.
Challenge: What diagnosis and syndrome are described here?

A patient is found with a suicide note in a car and brought in by ambulance. He complains of headache, malaise, nausea, and dizziness. He is too altered to give much more history. His skin looks a little red. Vital signs are: HR 70, BP 110/60, RR 16, O2 saturation 99% on room air, temperature 37. Cardiac biomarkers (CKMB and troponin) are elevated. A CT of the head, taken 16 hours later, is shown above. Weeks later, the patient still has some cognitive deficits, personality changes, and neurologic defects.
Challenge: What diagnostic test should the emergency department order?
