Cerebral venous sinus thrombosis detected using diffusion-weighted magnetic resonance imaging during maintenance temozolomide chemotherapy in a patient with glioblastoma: illustrative case.

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
backgroundCerebral venous sinus thrombosis (CVST) sometimes occurs in the background of hypercoagulopathic disorders, including malignancy, chemotherapy, etc. Glioblastoma (GBM) is a malignancy found in the central nervous system, and reports on cases of GBM complicated by CVST are sparse. The authors herein report a case of GBM complicated by CVST during maintenance temozolomide (TMZ) chemotherapy and describe the utility of diffusion-weighted magnetic resonance imaging (MRI) for the detection of CVST. OBSERVATIONS: A 65-year-old male was treated for left temporal GBM. After surgical removal of the lesion, the patient was treated with chemoradiation therapy, which included 60 Gy local radiation with concomitant TMZ chemotherapy. He was subsequently received TMZ maintenance therapy. Routine MRI performed 7 months after surgery revealed no evidence of tumor recurrence. However, diffusion-weighted imaging (DWI) revealed a high-intensity signal at the posterior portion of the superior sagittal sinus, indicating the presence of a thrombus. In addition to the preexisting symptoms, the patient experienced some disorientation. Angiography revealed an obstruction in the superior sagittal sinus, right transverse sinus, right sigmoid sinus, and straight sinus. His symptoms improved with endovascular and anticoagulant therapy. LESSONS: Performing DWI during routine follow-up can help in the early diagnosis of CVST in patients with malignant gliomas.
