The first report of pseudoaneurysm secondary to Cunninghamella bertholletiae infection in a Haematopoietic stem cell transplantation recipient: a case report and literature review.
Review in BMC infectious diseases, 2025. 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
backgroundMucormycosis is a life-threatening complication that occurs in haematopoietic stem cell transplantation (HSCT) recipients. Among mucormycosis patients, those infected with Cunninghamella bertholletiae have the poorest prognosis because of the high virulence and angioinvasive nature of this organism. Despite its high vascular invasiveness, pseudoaneurysm caused by C. bertholletiae in HSCT recipients has rarely been reported. CASE PRESENTATION: An 8-year-old HSCT recipient experienced recurrent fever, cough and pain after HSCT. Teicoplanin, acyclovir, posaconazole and caspofungin were used for infection prophylaxis. The sputum, stool, urine, peripheral blood and central venous catheter (CVC) blood culture results were negative. Next-generation sequencing (NGS) of the peripheral blood, pleural effusion and bronchoalveolar lavage fluid revealed the presence of C. bertholletiae, and amphotericin B combined with posaconazole was administered; however, the infection progressed. Fibreoptic bronchoscopies revealed that C. bertholletiae had invaded the bronchial wall, and enhanced computerized tomography (CT) revealed a pseudoaneurysm of the descending aorta resulting from C. bertholletiae. Debridement and vessel replacement were considered but not performed because of the severity of the infection and the patient's poor physical condition. Unfortunately, the patient died from pseudoaneurysm rupture with no presymptoms 56 d after HSCT.
conclusionFor the first time, we report pseudoaneurysm secondary to C. bertholletiae infection in a HSCT recipient, highlighting the importance of clinical awareness of vessel lesions resulting from C. bertholletiae and emphasizing the value of enhanced CT for the early detection of vessel lesions in this rare infection.
