:
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 benign causes in the differential diagnosis in patients presenting with findings
suggestive of diffuse bone metastasis.Because misdiagnosis may cause the patient to receive unnecessary treatments,
especially radiotherapy. In this case, we reached the diagnosis of benign disease, diffuse bone lymphangiomatosis, and 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 in the company with the clinical and radiological findings
of the patient, it should be approached with medical follow-up without treatment.
