Cervical thoracic duct cyst: Importance of preoperative suspicion for appropriate management of left-sided neck mass.

Cervical thoracic duct cysts occur infrequently but are an important consideration when evaluating cystic supraclavicular masses. Only 22 cases have been reported to date. We review the clinical presentation, evaluation, and treatment of 2 cases of large thoracic duct cysts treated with surgical resection.

Skull base osteomyelitis and bisphosphonate use in multiple myeloma: report of two cases and literature review.

Objectives: Although osteoradionecrosis of the mandible is a well known entity, skull base osteomyelitis involving the temporal bone unrelated to otitis externa in patients with multiple myeloma using bisphosphonates has not been reported. We described a new entity of skull base erosion resulting from osteonecrosis, presenting with malignant features in patients using bisphosphonates for multiple myeloma.

Methods: Two patients with multiple myeloma and prior zolendronic acid use were referred to our cancer center for management of maxillary and temporal bone masses with skull base erosion.
