Can you tell me what this means?
Findings: 1.9 x 2.5 x1.7 cm mass within the midline just anterior to the L5, S1 disk space. It is felt to be retoperitoneal, predominantly of fatty attenuation, but has a calfified rim. There are faint internal septations, but no nodular soft tissue density components. It is a solitary lesion and there is no additinoal evidence that would suggest adenopathy.
Impression: Retroperitoneal mass is in the midline with fatty density. Should be of concern for a teratoma. However, the appreance is really quite unusual for a teratoma given that the calcifications are circumferential and rim like. It is possible the patient had a lipoma with infarction. Low density, but calcified lymph nodes can be seen in various granulomatous diseases. Does the patient have a history of prior histoplasmosis? Nonetheless, I do believe that this lesion should at least be followed if not sampled in order to ensure benignity.
My regular doctor told me we could not biopsy because of location, and does not think it is causing any of my problems. She will follow up on it in 3 months.
Symptoms: weight loss, insomnia, swollen lymph nodes of the neck (under jaw line), extreme upper thigh pain, constant urination, night sweats.
Is this something to worry about?
