Woman 30 yo presented cervicalgia and swelling of the neck.
Chest Xrays: one mass at right of her neck.
Ultrasound detected thyroid gland normal( US1), but retrothyroidal spaces both 2 sides had hypoechoic masses, no vessels intra mass which were suspected abscesses ( see US 2:cross-section at lower part of the neck, and US 3:longitudinal scanning of the neck).
MSCT of the neck (CT1 image showing the normal thyroid gland and 2 mass at lateral cervical spine looked like abscess). Frontal view and sagital view detected osteolytic lesions at thoracic spine T1.
Ultrasound guided aspiration pus from abscess and detected BK positive in pus analysis.
It was a POTT' abscess of the neck, due to spine T1 tuberculosis.
