On 29.05.2015:
The patient is afebrile today with Blood pressure of 109/63, and pulse of 72/min. The patient looks ill and still complaining of headache. He is dehydrated and sweating. Throat shows signs of dehydration on examination (coated tongue) and there are[ no signs of congestion. Neurological consultation was done and advised for Widal Test which was negative. Chest X-Ray, CBC, Urine Analysis and culture, ESR, CRP and blood cultures. And then after the Widal test, Chest X-Ray and CBC were normal a CT Scan Brain with contrast was done. CT Scan revealed increased Leptomeningeal enhancement in the right fronto-temporal region and the basal cisterns, consistent with meningitis and right fronto-temporal subdural effusion with mass effect and midline shift (6mm) to the left and hence treatment for Meningitis begun. Patient was started on Manitol, Phenytoin, risek, Topomax, dexamethasone, Metoclopramide and Ceftiaxone. Patient was shifted to Isolation Room after the confirmation from the CT Scan.

CT Brain with Contrast:
     There is increased Leptomeningeal enhancement in right Fronto-Temporal region and the basal cisterns. A cresentric extra-axial collection with hypodense contents is seen in the right frontal location and extending into temporal region. It measures 7.5mm in maximum thickness, 10.6cm in transverse and 10.8cm in maximum craniocaudal extent. Mass effect is seen with partial effacement of frontal horn of right lateral ventricle and midline shift of 6mm to the left.
     Brain parenchyma shows normal attenuation pattern with well-preserved grey white matter differentiation.
     No significant parenchymal lesion is seen. Rest of the ventricular spaces are normal
     Brain stem and cerebellum appear normal
     Note is made of left frontal, ethmoid and left maxillary sinusitis
CECT Findings are suggestive of increased Leptomeningeal enhancement in the right fronto-temporal region and the basal cisterns, consistent with meningitis and right fronto-temporal subdural effusion with mass effect and midline shift (6mm) to the left.

On 30.05.2015:
The patient is feeling better as per the family. There are no irritability symptoms. His blood pressure is 115/78 mmHg, pulse is 86/min, respiratory rate is 20/min and temperature is 35.6 C. there are no new complaints and the patient is continuing on the medications.

Brief Answer:
May be given eptoin for prophylaxis in some cases

Detailed Answer:
I have gone through your question and understand your concerns.
After reviewing all history and reports possibility of infective meningitis is one possibility. Other possibility may be lymphoma or leukemia, sarcoidosis.
Present condition requires neurosurgery opinion for intervention as symptoms and signs of raised intracranial pressure is there.
antibiotics should be continued.
Csf analysis when feasible with no risk of herniation may be done but not at present condition.
Prophylaxis eptoin is usually not given but some physician prefer to give prophylaxis if cortical or subdural collection are present.
In present case eye deviation may be a manifestation of seizure and so treatment to be continued.
possibility of tubercular meningitis should also be considered.
hope you found the answer helpful.
do get back to me for further queries.
