The textbook sources give us clear, authoritative information. Here is the answer:

Complications of Disseminated (Miliary) Tuberculosis

The correct answer is 2) Tuberculous uveitis and 3) Poncet's disease (rheumatoid Poncet).
Here is a full analysis of each option:

✅ 2) Tuberculous Uveitis — TRUE complication of disseminated TB

Disseminated (miliary) TB involves hematogenous seeding of multiple organs. The eye is one of the organs that can be affected, and tuberculous uveitis is a well-recognized manifestation. It occurs through bloodstream spread of M. tuberculosis to the uveal tract and is listed among the varied clinical manifestations of disseminated disease. Anterior, intermediate, posterior, and panuveitis have all been described in association with TB.
— Harrison's Principles of Internal Medicine 22E; Kanski's Clinical Ophthalmology 10th ed.

✅ 3) Poncet's Disease (Reactive/Rheumatoid Arthritis) — TRUE complication of disseminated TB

Poncet's disease is a reactive, symmetric polyarthritis that specifically affects persons with visceral or disseminated tuberculosis. Key features:
  • No mycobacteria are found in the joints (immune-mediated, not direct infection)
  • Symptoms resolve with antituberculous therapy
  • It is classified as a hypersensitivity/immunologic manifestation of TB
  • It is sometimes associated with erythema nodosum (another tuberculid reaction)
"An unusual syndrome, Poncet's disease, is a reactive symmetric form of polyarthritis that affects persons with visceral or disseminated tuberculosis. No mycobacteria are found in the joints, and symptoms resolve with antituberculous therapy." — Harrison's Principles of Internal Medicine 22E, p. 1832
"When reactive arthritis occurs in conjunction with erythema nodosum, the syndrome is referred to as Poncet disease." — Goldman-Cecil Medicine

❌ 1) Intestinal Tuberculosis — NOT a complication of disseminated TB (primarily)

Intestinal TB most commonly results from:
  • Swallowing of infected sputum in patients with advanced pulmonary TB
  • Drinking contaminated milk (bovine TB, M. bovis)
  • Occasionally, military spread can seed the intestine, but this is not its primary or defining association
It is primarily a complication of pulmonary TB (swallowed bacilli), not specifically of hematogenously disseminated disease.
— Robbins, Cotran & Kumar Pathologic Basis of Disease; Sleisenger & Fordtran's Gastrointestinal and Liver Disease

❌ 4) Tuberculosis of the Tonsils — NOT a classic complication of disseminated TB

Tonsillar TB is a rare form of oropharyngeal/extrapulmonary TB. It is primarily associated with primary TB from ingestion of infected material or local spread, not a recognized complication of the disseminated/miliary form.

❌ 5) Tuberculosis of the Larynx — NOT a complication of disseminated TB

Laryngeal TB arises from endobronchial spread — either via lymphatic channels or from expectorated infectious material (sputum contamination). It is a complication of active pulmonary TB, not of hematogenous dissemination.
"Endobronchial, endotracheal, and laryngeal tuberculosis may develop by spread through lymphatic channels or from expectorated infectious material." — Robbins, Cotran & Kumar Pathologic Basis of Disease, p. 1871

Summary Table

OptionComplication of Disseminated TB?Mechanism
1. Intestinal TB❌ NoMainly swallowed sputum / contaminated milk
2. Tuberculous uveitis✅ YesHematogenous spread to uveal tract
3. Poncet's disease✅ YesImmune-mediated reactive arthritis in disseminated TB
4. Tonsillar TB❌ NoIngestion / local spread, not dissemination
5. Laryngeal TB❌ NoEndobronchial / expectorated material from pulmonary TB
The best answers are 2 and 3.
