Cystic lymphangioma presenting with multiple bone lesions in an adult patient is a rare
occurrence, with a limited number of reported cases in the literature. In this case report, we describe
a 32-year old female patient with chronic neck and pelvic pain, and multiple lytic bone lesions
on radiological imaging, which were eventually discovered to originate from cystic hygroma
and widespread bone lymphangiomas that were present for more than 10 years. It should be kept in
mind that there may be multiple benign causes of differential diagnosis in patients presenting with
findings suggestive of diffuse bone metastasis. Misdiagnosis may cause the patient to receive unnecessary
treatments, especially radiotherapy. In this case, we reached the diagnosis of benign disease,
diffuse bone lymphangiomatosis. For this purpose, we also examine the long and stable medical
history of the patient with the findings of BT, ultrasound, and bone scintigraphy.
We think that as long as there are no stable and serious results ofclinical and radiological findings
of the patient, the patient should be approached with medical follow-up without treatment.
