| Diagnosis | Neurocysticercosis and Ruptured Subarachnoid Aneurysm | |
| History | The patient is a 54-year-old man who presents with sudden onset headache, nausea, vomiting and hypertension. Prior to these symptoms, he had been in his usual state of health. | |
| Findings | ||
| Differential Dx | Metastatic lesions characteristically lodge at the corticomedullary junction and can enhance in a ringlike pattern, and often present with more edema than expected for the size of the lesion. A High Grade Astrocytoma (WHO 3 or 4) can be included in the differential, although they are more likely to be heterogeneous with irregular borders. Fluid suggests parasitic infections, including cysticercosis, paragonimiasis, or echinococcus. | |

| Diagnosis | Subarachnoid Hemorrhage | |
| History | 77 y.o. male with acute loss of consciousness and a fall. He presents to the Emergency Department with an altered sensorium and severe headache. | |
| Findings | Non contrast head CT revealed a large amount of acute hyperdense material consistant with blood product in the Subarachnoid spaces with a relatively large amount within the right sylvian fissure. This was concerning for atraumatic Subarachnoid hemorrhage from a ruptured aneurysm in the distribution of the right middle cerebral artery. | |
| Differential Dx | Subarachnoid hemorrhage from ruptured aneurysm or acute trauma, hyperdense CSF from bacterial meningitis (much less likely), Subarachnoid blood and intraparenchymal from acute infection such as herpes encephalitis (much less likely), contrast in the CSF from myelogram (excluded from the differential diagnosis by history). | |
