Medicine (image-based) Question 7 of 20

An 18-year-old woman presents to the emergency department complaining of chest discomfort. On physical examination, she is mildly tachypneic. Her past medical history is significant for a seizure disorder. Her chest x-ray shows a 6-cm masslike structure in the left lung with central cavitation and an air-fluid level. What is the most likely diagnosis?

Chest x-ray of a young woman
  • AFungal pneumonia
  • BSquamous cell carcinoma of the lung
  • CLung abscess
  • DPulmonary embolus
  • EWegener granulomatosis
CorrectAll
Try again

Correct. The answer is C.

Key takeaway

A cavitary lung lesion with an air-fluid level in a patient at risk for aspiration is a lung abscess until proven otherwise.

What students say

Built for the boards

Made for medical students and graduates preparing for USMLE Step 1 and Step 2 CK.

Student review

“One thing I really appreciate is how much content is available. The written notes are useful when I want a proper revision session, while the Knowledge Hub articles are great when I need to understand a particular topic. The anatomy reveal plates are also a nice touch. I didn't expect to find so many different learning tools in one place.”

“I initially came for the interactive cases, but ended up exploring the rest of the platform too. The cases are genuinely fun to work through because you have to think about the diagnosis rather than just pick an answer. I also really like the Knowledge Hub. Having so many medical topics and articles in one place is super convenient when I want to quickly revise something.”
Dr. Ananya Sharma · USMLE Step 1: Pass · Preparing for Step 2 CK
“I've used AMBOSS and a few other resources during my preparation, and I think this platform brings something different to the table. The interactive cases are my favourite part because you actually have to work through the clinical findings. I also use the flashcards for quick revision. It's nice having different ways to study without constantly switching between websites.”

FAQ

Common questions

One purchase gives you the whole platform:

  • 3,907 exam-style MCQs with explanations, 2,042 of them built on images
  • 7,816 pages of Medical Notes in 1,235 notes across 23 subjects
  • 1,550 Knowledge Hub articles across 25 body systems
  • 34,919 flashcards that schedule themselves with spaced repetition
  • 849 labelled anatomy illustrations, 2,018 Gems and 1,000 Tables
  • Timed and untimed tests, a full review after every block, and analytics that flag your weak subjects

Yes. The bank spans 35 subjects and 1,858 topics, from the basic sciences Step 1 leans on to the clinical subjects at the heart of Step 2 CK.

Use it for Step 1 in your preclinical years, then keep going with the same account into Step 2 CK. Your history, bookmarks and weak areas come with you.

35 subjects, including Anatomy, Physiology, Biochemistry, Pathology, Pharmacology, Microbiology, Immunology, Genetics, Embryology, Behavioral Science and Biostatistics, plus every organ system, Medicine, Surgery, Pediatrics, Obstetrics & Gynecology and Psychiatry.

Each subject is broken into topics, so you can build a block as broad as a whole system or as narrow as a single topic.

Free decks, videos and review books are good for content review, but they mostly help you remember facts. Step 1 and Step 2 CK test whether you can apply those facts to a patient you have never seen.

Here you practise exactly that on clinical vignettes, and everything you need to close a gap sits in the same place: the explanation, the matching Medical Note, the Knowledge Hub article and the flashcards. No switching between tabs, decks and PDFs.

Questions are written as clinical vignettes in the style of the exam: a patient, the findings, often an image, and one best answer. 2,042 of them are built on radiographs, histology slides, ECGs and clinical photos, because the real exam leans on images too.

Exam mode runs a timer and hides the answers until you submit, so a block feels like test day.

Every question explains why the right answer is right and ends with a key takeaway worth remembering. Most also explain why each wrong option is wrong, so you learn the whole differential, not just one fact.

Images in explanations open full size, and the matching Medical Note is one tap away when a topic needs more than a paragraph.

Yes, 2,042 of them: radiographs, histology slides, ECGs and clinical photos, all zoomable.

Yes. Build a block of up to 60 questions from any subject or topic, and choose all questions, unseen, incorrect or bookmarked ones.

  • Exam mode hides the answers until you submit, like test day
  • Practice mode shows the answer and explanation as soon as you choose
  • 7 ready-made mixed blocks (332 questions) let you rehearse a full spread of subjects

After each block you get a full review: time per question, results by subject, and one-click retry of everything you missed.

Aim for one full pass of the bank, then a second pass of everything you got wrong.

  • During coursework, 10 to 20 questions a day in practice mode completes a full pass of 3,907 questions in roughly 7 to 13 months
  • In dedicated study, move to full timed blocks and use the Incorrect filter for your second pass

The goal is not to finish questions but to learn from them. Read the explanation for every question you miss or guess.

Yes, and it works best that way. Use practice mode alongside your coursework to see the answer and explanation straight away, then switch to timed exam-mode blocks during dedicated study.

There is no automatic study planner. Set a daily question goal in your settings and the dashboard keeps you on it with your streak, accuracy trend and weakest subjects, so you always know what to do today.

Watch your trend, not a single block. You are on track when:

  • Your accuracy on timed, mixed blocks keeps rising
  • The weakest subjects on your dashboard keep improving
  • You can say why each wrong option is wrong, not just pick the right one

Our blocks are built for learning, not score prediction. For a predicted score, take the official NBME self-assessments as your exam approaches.

No. You can filter by subject, topic and status (unseen, incorrect or bookmarked). High-yield topics turn up at every level of difficulty, so working through the full bank leaves you with fewer gaps.

It covers what most students need in one place: 3,907 exam-style questions, the full Medical Notes, 1,550 Knowledge Hub articles, flashcards and analytics. It does not include video lectures.

Yes. Build blocks from only your weakest subjects or your incorrect questions, retry everything you missed in one click, and open the matching Medical Notes and Knowledge Hub articles to rebuild those topics from the ground up.

Pay once, with no subscription and nothing to renew. The platform stays yours through Step 1, Step 2 CK and on until you are a Resident.

Yes. Everything works in the browser on your phone, tablet or laptop, and there is an iOS app too.

Yes. Read 3 complete Knowledge Hub articles free every day, no account needed, and try the sample question at the top of this page.
