RADIOLOGICAL FOLLOW-UP IN ENCAPSULATED INTRACEREBRAL HEMATOMA MIMICKING INTRATUMORAL BLEEDING

Chronic encapsulated intracerebral hematoma, which is usually seen in young, normotensive patients, is rare, but has been reported with incr easing frequency in recent years. In this report, we have presented a case of encapsulated intracerebral hematoma mimicking intratumoural bl eeding with its whole natural radiological progression. A 55 year-old man developed a progressive neurological deficit one month after hospi talisation due to spontaneous intracerebral hemorrhage. Cranial CT and MR demonstrated a ring-shaped hemorrhagic lesion with mass effect and perifocal edema. After 15 months, there was marked improvement in cli nical findings, and imaging techniques showed marked resorption of the mass. Radiological findings of spontaneous resolution of the encapsul ated intracerebral hematoma are described for the first time in the re ported case. Encapsulated intracerebral hematoma can present much like a brain tumour and should be considered in the differential diagnosis of other hemorrhagic space-occupying lesions.
