Background: Minocycline is frequently utilized for multiple
drug- and extensively drug- resistant bacteria (XDR), but is associated
with many side effects. Idiopathic intracranial hypertension is one such
effect resulting from the precipitation of raised intracranial pressure
(ICP), manifesting as headaches, diplopia or even vision loss. The aim
of this study is to present a case of Philadelphia chromosome positive
acute lymphoblastic leukemia (Ph+ ALL) with XDR Escherichia. coli (E.
coli) treated with minocycline. This resulted in elevated ICP with
associated symptoms which were initially thought to be due to central
nervous system (CNS) involvement by primary disease. Case presentation:
A 14-year-old girl was given minocycline therapy for XDR E. coli, which
was cultured from her blood, for two weeks. Patient develop complaints
of nausea, vomiting, headache blurring and doubling of vision one week
into therapy. Lumbar puncture and brain imaging were performed to rule
out CNS involvement with Ph+ ALL, which were reported as negative for
malignancy. Minocycline was suspected to have precipitated the event and
was discontinued. The patient recovered within one week after cessation
of therapy. Conclusion: Minocycline can be associated with symptomatic
elevation of intracranial pressure, which can easily be mistaken for CNS
involvement in patients with neoplastic disease, and can reverse upon
discontinuation of the drug.
