Orbital lymphangioma: Considerable Shrinkage without Biopsy and Surgery

Hirohiko Kakizaki, Yasuhiro Takahashi, Akihiro Ichinose and Masayoshi Iwaki

A 5-year-old girl presented with a sudden left proptosis just after being hit by her sister's hand. The Hertel measurements were 8 mm OD and 12 mm OS. Computed tomography scans disclosed an extensive multi-cystic mass in the left orbit with niveau formation. Based on these findings, the tumor was diagnosed as "orbital lymphangioma". Since the patient could close her eyes completely without corneal involvement and visual acuity loss, we did not perform a biopsy or surgery. Four months later, her left proptosis improved (Hertel: 10.5 mm). Five months after this examination, her left proptosis further improved (Hertel: 8 mm, OU). The proptosis showed a symmetrical appearance. Computed tomography scans showed considerable shrinkage of the tumor. This is the first case report of an orbital lymphangioma with detailed description of considerable spontaneous shrinkage without stimulation from a biopsy and surgery.
