How will you diagnose the Lymphangiomas?

As a rule the diagnosis is apparent and are made on clinical grounds

Ultrasound scanning may help

• To make prenatal diagnosis and there are report of infants being treated ex-utero to airway problems at birth.
• It reveals the cystic nature of the lesion and it relationship to the surrounding tissues.
• It will distinguish between micro and macrocystic disease.

CT and MRI delineates

• the extent of the lesion.
• facilitates accurate diagnosis and pre-treatment planing.
• Determine size and the exact anatomical location
• Demonstrates it relationship with surrounding structure

MRI preferred more due to soft tissue delineation better and avoidance of ionizing relation.

(No operation should be conducted without pre-operative chest CT scan to R/O mediastinal involvement)

no/little value only if underlying neoplasia is suspected.
