Abstract

Patient: Female, 21.

Final diagnosis: Tuberculous lyphadenitis.

Symptoms: Cough dry • fever • subcutaneous mass • weight loss.

Medication: -

Clinical procedure: -

Specialty: Pulmonology.

Objective: Unusual clinical course.

Background: Enlargement of lymph nodes during treatment of Tuberculous lymphadenitis is well recognized phenomenon in HIV infected patient with ample literature to help guide management. On the contrary, it poses a clinical challenge to distinguish between paradoxical reaction and treatment failure in HIV-seronegative patients and require high index of suspicion.

Case report: We report a case of 21 year old female of Bangladeshi origin with tuberculous lymphadenitis diagnosed on the basis of strong clinical history and radiologic findings. Patient's clinical symptoms and lymphadenopathy initially improved but worsened after three months of RIPE therapy. This prompted re imaging and excision biopsy of enlarging lymph node to exclude other masqueraders. Patient was continued on same antituberculous treatment. Oral prednisone was added with subsequent clinical improvement and decrease in the size of lymphadenopathy.

Conclusions: Paradoxical reaction during anti tuberculous treatment must be considered after careful exclusion of medication non adherence, development of resistance and other similar conditions.

Keywords: Kikuchi’s disease (KD); highly active anti-retroviral therapy (HAART); isoniazid; paradoxical reaction (PR); pyrazinamide and ethambutol (RIPE); rifampin; tuberculosis (TB); tuberculosis lymphadenitis (TL).
