The patient developed gradual loss of vision after two years and a review CT scan revealed the local recurrence of tumour with dystrophic calcification of the basal ganglia, frontal and temporal subcortical regions representing recurrent craniopharyngioma with radiation-induced mineralizing microangiopathy. Mineralizing microangiopathy Lateral radiograph of 14 year old boy who underwent radiotherapy and chemotherapy for right frontal glioma shows linear tram tack calcification in the frontal region. CT scan of the same patient showed caorse gyral patternn calcification in the roght frontal region with white matter edema in bilateral frontal lobes. His clinic-radiological presentation was thus consistent with mineralizing angiopathy with basal ganglia stroke. Mineralizing angiopathy may be an underrecognized cause of pediatric stroke. Thin-section spiral CT with multiplanar reconstructions may be prudent in children developing focal deficits following trivial trauma. Further research is . We propose that this CT demonstrable form of mineralization, along the lenticulostriate arteries, be termed as ‘mineralizing angiopathy’ to differentiate it from SLV. Further longitudinal studies are required to identify the factors associated with persistence of the lenticulostriate artery mineralization in these infants. Kidz love soccer shirt.

    The intracranial CT findings of mineralizing microangiopathy, a rare condition, are described in seven patients. The underlying pathology was posterior fossa medulloblastoma (four patients), cerebelloastrocytoma (two patients), and acute lymphatic leukemia (one patient). Brain irradiation and primary brain tumors affect signal intensity within the dentate nucleus and globus pallidus independent of gadolinium administration in pediatric patients. With the use of current treatments, this severe form of leukoencephalopathy is seen infrequently. The subclinical form of leukoencephaly is more common, characterized by radiologic abnormalities on CT scan and MRI without clinical symptoms. It occurs in approximately 55-60% of patients receiving CNS prophylaxis. Nonirradiated patients generally ...

    serious consequences. The appearances of mineralizing microangiopathy are specific; but the nature of the other complications is only evident in the clinical context, although there may be difficulty distinguishing between radiation necrosis and further growth of an intracerebral tumor. Selected cases illustrate the computed tomographic features However, radiation-induced temporal lobe changes are intraaxial abnormalities, and cerebral edema is a common early sign. Radiation-induced changes are usually indolent and the radiologic signs often persist for years. Such an indolent course is unexpected in patients with recurrent tumor. Therefore, in the absence of a nasopharyngeal mass or ...
