Our purpose is to illustrate and describe the radiological appearance of hypothalamic/chiasmatic pilocytic astrocytoma in adult population,
describing typical and atypical imaging findings with computed tomography (CT) and magnetic resonance imaging (MRI).
We report 3 cases of adult cerebral pilocytic astrocytomas,
two of them young adults,
presenting with severe headache,
nausea and vomitting.
Non-contrast computed tomography (CT) and magnetic resonance imaging (MRI) with gadolinium were performed,
revealing acute intratumoral hemorrhage.
Findings and procedure details
Case 1 A 28-year-old woman with no past medical history presented to the emergency department with 10 days of headache accompanied with blurred vision. Firstly,
a non-contrast CT was performed,
revealing a hyperdense nodular lesion in the supraselar/chiasmatic region.
computed tomographic angiography did not show any vascular abnormality or enhancement.
The patient was transferred to neurosurgery service with a suspected supraselar tumor. Magnetic resonance imaging (MRI) of the head...
Although often being highly vascular tumors,
the presentation of cerebral pilocytic astrocytomas with intracranial hemorrhage is extremely rare,
it should be considered during differential diagnosis of intracerebral hemorrhages in that location.
