Thoracic intramedullary neurosarcoidosis with thoracic disc herniation: Diagnostic importance of intramedullary contrast enhancement.
Article in Surgical neurology international, 2021. 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
backgroundThoracic intramedullary neurosarcoidosis is an uncommon but serious manifestation of spinal cord disease. Its concomitant occurrence with thoracic disc herniation can mislead the physician into attributing neurologic and radiographic findings in the spinal cord to disc pathology rather than inflammatory disorder. Here, we present such a rare case of concomitant thoracic disc and spinal neurosarcoidosis. CASE DESCRIPTION: A 37-year-old male presented with progressive right lower extremity weakness and numbness. Magnetic resonance imaging (MRI) of the thoracic spinal cord revealed a T6-T7 paracentral disc eccentric to the right with T2 signal change extending from T2 to T10 level. This prompted acquiring a contrasted MRI that also depicted intramedullary enhancement around the T6-T7 disc bulge. Computed tomography scan of the chest showed mediastinal lymphadenopathy concerning for sarcoidosis. Lymph node biopsy confirmed the diagnosis of sarcoidosis, and high-dose steroid treatment was initiated. The patient had significant symptomatic improvement with steroids with full neurological recovery and improvement of his symptoms.
conclusionWhile stenosis from thoracic disc disease could potentially suggest a mechanical etiology for the patient's symptoms, attention must be paid to the imaging findings as well as the degree and extent of cord signal change and intramedullary contrast enhancement. Appropriate and timely diagnosis is essential to avoid unnecessary invasive procedures.
