Name: Aliyaru kunju

Age: 62 Yrs

Sex: Male

Complaints: c/o ataxia

Introduction:

• Case study: Bilateral cerebral hemisphere shows well defined encapsulated hypodense subdural collection involving right parietal and left fronto-parietal region with maximum thickness in the right parietal region measuring ~28 mm showing irregular areas of hyperdensities.
• Well defined encapsulated hypodense collection measuring ~4.7 x 1.5 cm involving the epidural space of right frontal lobe extending into the parietal region with minimal evidence of peripheral hyperdensities.
• No evidence of significant mass effect/ midline shift at present.

Conclusion: Well defined encapsulated subdural hypodense collections in the bilateral cerebral hemisphere with evidence of hyperdensities.  – Features in favor of acute on chronic SDH.

Well defined encapsulated epidural hypodense collection in the right fronto-parietal region with peripheral areas of hyperdensities as described. – Features in favor of acute on chronic EDH.

No evidence of significant mass effect/ midline shift at present.

Age: 61yr

Sex: Female

Complaints: H/o deviation of angle of mouth

Case study: Poorly defined scattered irregular hypodensities (max. 18HU) noted in the bilateral high parietal region involving the corona radiata and centrum semi ovale. – Features suggestive of acute/subacute infarct.

Images:

Conclusion: Poorly defined irregular hypodensities in the bilateral high parietal region as described. – Features in favour of acute/subacute infarct – showing watershed characteristics.No mass effect/midline shift/hemorrhagic transformation at present.
