Bilateral Meckel's Cave Cephalocele Presenting as Cranial Nerve VI Palsy: A Case Report.
Article in Case reports in neurology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Meckel's cave cephalocele, also known as petrous apex cephalocele (PAC), is a rare cystic lesion caused by herniation of the cerebrospinal fluid into the Meckel's cave. Bilateral PACs are exceptionally rare, with only 21 reported cases. PACs may present with headache, diplopia, tinnitus, or cranial nerve palsy. Case Presentation: A 74-year-old male presented with acute onset headache, vision changes, and gait instability. His medical history included hypertension and melanoma. Examination revealed a left cranial nerve VI palsy. Initial imaging with head CT and CTA showed no acute intracranial abnormalities but revealed moderate chronic sinusitis. Magnetic resonance imaging demonstrated large bilateral Meckel's cave cephaloceles, more prominent on the left, with mass effect on the inferior margins of the cavernous sinus. Steroid treatment was initiated for suspected influenza-associated cranial neuropathy. Follow-up did not reveal an immediate improvement. However, after several weeks of steroid treatment, his symptoms improved significantly. The patient deferred surgical intervention. Conclusion: This case highlights a rare presentation of bilateral PACs with cranial nerve VI palsy. Although surgical intervention may be definitive, conservative treatment can provide relief of symptoms in select cases. More research is needed to guide optimal management strategies.
