Lymphangioma diagnostic study of choice

Diagnostic Study of Choice

Study of choice:

• MRI is the gold standard test for the diagnosis of lymphangioma.
• MRI can mar the degree of involvement and extent of lesion.
• MRI can prevent extensive, incomplete surgical resection, because poorly removed lesion can lead to recurrence.

Biopsy:

Biopsy is used to analyze the structure of tissue. It shows

• Dilated lymph channels ultimately causes the papillary dermis to expand.
• THese channels extend to subcutis.
• Deeper vessels have larger lumen and muscular coat.
• The lumen has lymphatic fluid, but it often contains red blood cells, lymphocytes, macrophages, and neutrophils.
• These channels re lined by endothelial cells.
• Numerous lymphoid cells are also seen.

Histochemical staining:

• Histochemical staining is recommended to document lymphangioma.

Other Tests:

In addition to above, various investigations must be performed in the following order:

• Plain radiograph
• Ultrasound
• CT scan
