MIMIC-III, a freely accessible critical care database.

MIMIC is an openly available dataset developed by the MIT Lab for Computational Physiology, comprising deidentified health data associated with ~40,000 critical care patients. It includes demographics, vital signs, laboratory tests, medications, and more.

The "medical.arff" dataset contains radiology reports annotated with multiple labels (ICD-9-CM codes ). However, it is preprocessed, i.e., the raw text was transformed into a bag of words representation.

You can find this dataset at the mulan repository: http://mulan.sourceforge.net/datasets-mlc.html
