# Case of nasopharyngeal tuberculosis complicated with cervical lymph node and pulmonary tuberculosis

## TL;DR

This paper reports a rare case of tuberculosis affecting the nasopharynx, cervical lymph nodes, and lungs, highlighting the importance of thorough diagnosis.

## Contribution

The paper presents a rare case linking nasopharyngeal TB with cervical lymph node and pulmonary TB, emphasizing the need for nasal endoscopy in such cases.

## Key findings

- A case of nasopharyngeal TB combined with cervical lymph node and pulmonary TB was diagnosed and treated successfully.
- Radiographic findings suggested TB despite negative smear tests, and treatment led to resolution of symptoms.
- The case underscores the importance of nasal endoscopy in diagnosing nasopharyngeal TB.

## Abstract

Multiple cases of extrapulmonary tuberculosis (TB) combined with pulmonary TB are commonly encountered in clinical practice. Nasopharyngeal TB is often ignored because of its hidden location and nonspecific manifestations. A correlation between cervical lymph node and nasopharyngeal TB has been observed; however, reports of cervical lymph node TB complicated with nasopharyngeal TB are rare, potentially leading to missed diagnosis. Herein, we present a case of nasopharyngeal TB combined with cervical lymph node and pulmonary TB. Radiographic findings consistently suggested TB, although multiple smear tests’ results were negative. After 3 months of diagnostic anti-TB treatment, the nasopharyngeal TB completely disappeared, and the swollen cervical lymph nodes subsided after 1 year of treatment. This case report deepens our understanding of nasopharyngeal TB and emphasizes the need for nasal endoscopy in patients with cervical lymph node TB.
