Final answer:
The symptoms described are consistent with intracranial hypertension, which can be caused by the use of isotretinoin. A healthcare professional should be consulted for evaluation and management.
Step-by-step explanation:
The symptoms described in the question, including severe occipital headache, bilateral papilledema, and elevated opening pressure on lumbar puncture, along with normal CT scan findings, are consistent with a condition known as intracranial hypertension. There are several possible causes of intracranial hypertension, one of which is a medication called isotretinoin. Isotretinoin, commonly used to treat chronic acne, has been associated with various adverse effects, including central nervous system abnormalities.
The elevated opening pressure on lumbar puncture suggests increased pressure within the skull, which can lead to symptoms such as severe headache and papilledema (swelling of the optic disc). The absence of cells, low glucose, and elevated protein in the cerebrospinal fluid (CSF) can also be seen in cases of intracranial hypertension.
It is important for the student to consult with a healthcare professional for a proper evaluation and management of their symptoms.
