Intracranial tuberculoma - MRI brain

Case contributed by Dr G Balachandran


Recent onset of seizures.

Patient Data

Age: 40
Gender: Male

MRI demonstrates a 2cm rounded lesion in the anterior pole of the left frontal lobe. The lesion is mostly isointense to grey matter, with perhaps small regions of hyperintensity on T1 and T2 weighted images. Of note, there is no well defined central region of T2 hyperintensity. Very extensive vasogenic edema is present extending back to the precentral region. ADC demonstrates increased values centrally, making a conventional bacterial abscess unlikely. 

Following administration of contrast the lesion enhances relatively homogeneously. 

Case Discussion

The vast amount of edema, lack of central liquefaction / restriction and knowledge of the patient's demographics (the patient lives in India) makes a tuberculoma the most likely diagnosis (subsequently confirmed).
