u 2 days later the patient returned to the hospital ED and a left PNTX was noted on CXR with progression of pneumonia. u ON 1/3/05 the patient was admitted and left chest tube was placed. u The week following, the patient had left chest tube removed but developed worsening pulmonary infiltrates and respiratory distress.

u ID consultant noted on 1/07/05 – Failure to respond to “standard antibiotics” – Persistent fever but no leukocytosis – Negative sputum and blood cultures – Therefore unusual organism suspected – Vacomycin, zosyn, and azithromycin initiated – Plans to obtain bronchoscopic washings if no improvement

1/10/05

u. A pulmonary consult was called on 1/10/05. u The patient was transferred to the ICU, intubated and bronchoscoped. u A PPD was placed on 1/9/05 and was 5 mm. u Bronchoscopy revealed 4+ AFB u Patient was placed on INH, RIF, PZA, and SM.

Summary u This 25 year old female, presented with signs and symptoms of CAP- was treated with ceftriaxone and azithromycin for 10 days until florid necrotizing TB diagnosed on 1/10/05 from bronchoscopic washings. Treatment included ventilatory support, 5 drug TB chemotherapy and nutritional support. Initially 3 of the 5 TB drugs were given parenterally : RIF, Levaquin intravenously +SM-SC subcutaneously.

u PZA/INH were given via GT. No index case was ever confirmed and no intrahospital transmission occurred. With regards to household contacts, all were negative, except a nephew and her boyfriend. Extensive hospital contact review showed no conversions of PPD. The patient sustained moderate RLD from acute lung injury but has recovered fully and has returned to work full time. Probable factors leading to severity of her disease: Diabetes and possibly poor diet.

u Rare cases of fulminating necrotizing pneumonia caused by TB have been reported. Fortunately this organism was pan-sensitive and responded to administered anti-microbials. The patient although near death from ARDS survived a 2 ½ month hospitalization to fully return to an active life. Amazingly, few if any contacts were infected by her.
