The Clinical Problem Solvers Episode 364 – Clinical Unknown – Lea and Şeyma discuss Elena’s case
Nov 7, 2024
A diagnostic journey through two weeks of cough, fever and breathlessness after antibiotics failed. Discussion centers on clues like lymphadenopathy, oral thrush and HIV testing. Imaging and labs reveal ground glass changes, cytopenias and systemic inflammation. Final pathology and HHV8 testing point to a surprising multicentric lymphoproliferative process.

Episode notes
Antibiotic Failure Means Rethink Diagnosis
- Unresolved febrile cough with antibiotic failure suggests an inflammatory or nonbacterial cause rather than typical CAP.
- Leah and Şeyma highlighted failure causes: wrong diagnosis, wrong drug, wrong bug, insufficient penetration, or viral/atypical pathogens in a treated outpatient.
Test For HIV And Syphilis Early With Systemic Lymphadenopathy
- In a patient with systemic lymphadenopathy and oral candidiasis, prioritize HIV and syphilis testing and assess for immunosuppression.
- Ask about recency of HIV test, exposures, genital exam for ulcers or discharge, and repeat testing if risk continues.
Upper Lobe GGOs With Organomegaly Suggest Disseminated Disease
- Upper-lobe predominant ground glass opacities plus hepatosplenomegaly and cytopenias point toward reticuloendothelial or disseminated processes, not simple bacterial pneumonia.
- Şeyma emphasized TB, endemic fungi, PJP, and marrow/reticuloendothelial involvement given splenomegaly and cytopenias.
