Cerebral Abscess Masquerading as Tuberculoma in a Post-Renal Transplant Chronic Kidney Disease Patient: A Diagnostic and Therapeutic Challenge.
Article in Clinical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Solid organ transplant recipients are at increased risk of acquiring serious infections. We present a case of a 48-year-old male with a history of renal transplantation in 2012, chronic kidney disease (CKD) Stage 4, hypertension, uncontrolled diabetes mellitus, and prior tuberculous pleural effusion. Laboratory investigations revealed significant renal impairment, persistent hyponatremia, hypokalemia, and subtherapeutic tacrolimus levels (2.50 ng/mL), reflecting challenges of CKD and chronic immunosuppression with mycophenolate mofetil and tacrolimus. Given his immunocompromised state and TB history, initial suspicion centered on intracranial TB reactivation. Brain MRI with contrast revealed a rim-enhancing lesion in the right parieto-occipital region with central diffusion restriction, suggestive of a cerebral abscess. Magnetic resonance spectroscopy (MRS) demonstrated elevated lactate (1.33 ppm) and amino acid peaks, confirming the diagnosis and excluding tuberculoma or high-grade glioma. Treatment included intravenous ceftriaxone, dexamethasone, and a CKD-adjusted anti-TB regimen (rifampicin, isoniazid, ethambutol, pyrazinamide), alongside phenytoin and continued immunosuppressants. This case underscores the diagnostic complexity of distinguishing cerebral abscesses from tuberculomas in post-transplant patients, highlighting the pivotal role of multi-modal imaging (MRI, MRS) and tailored therapy to manage infection, immunosuppression, and comorbidities effectively.
