SECONDARY
ADENOCARCINOMA OF THE BRAIN |
ALTERNATE NAMES

Adenocarcinoma Brain Metastasis; Brain Adenocarcinoma; Metastatic Adenocarcinoma of
the Brain

DESCRIPTION
|
Secondary Adenocarcinoma of the Brain is a brain lesion caused by the spread of cancerous cells from a malignant tumor
in another organ. Adenocarcinomas usually metastasize to the brain from primary tumors
in the lung, though metastases originating in the breast or gastrointestinal organs
have been observed.
Adenocarcinoma is a type of cancer that begins in glandular (secretory) cells. Glandular
cells are found in tissue that lines certain internal organs that make and release
substances in the body.

DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM/ICD-10-CM
CODING
|
Diagnostic testing:
The diagnosis is established by:
-
•
History and physical examination;
-
•
Brain imaging (CT or MRI scans);
-
-
-
Physical findings: Common symptoms include:
-
-
-
-
-
•
Slurred or confused speech;
-
-
•
Numbness or weakness on one side of the body; and
-
ICD-9: 198.3
ICD-10: C79.31
|
PROGRESSION
|
The prognosis for individuals with secondary adenocarcinoma of the brain is generally
poor. Long-term survival is very rare but has been known to occur with aggressive
treatment and therapy.
|
TREATMENT
|
Approach to treatment varies based on the site and aggressiveness of the primary tumor,
but typically involves a combination of surgery, radiation, and chemotherapy.
Initial response to treatment tends to be favorable, but relapse within one year is
common. Neurological impairment is a frequent side effect of treatment.

SUGGESTED
PROGRAMMATIC ASSESSMENT* |
Suggested MER for Evaluation:
-
•
Clinical history and examination that describes the diagnostic features of the impairment;
-
•
Imaging reports such as CT scan or MRI scan;
-
