Acute phantosmia as the first manifestaton of brain metastases in a patient with breast cancer. Case report.
Article in BioMedicine, 2025. 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
Phantosmia belongs to the group of olfactory dysfunctions. It is more commonly described in psychiatric conditions and some cases of viral infections, but it has been also rarely described in cancer patients who develop primary or metastatic central nervous system tumors; the early identification of this symptom in this population is crucial, as it could lead to timely diagnosis and treatment through a multidisciplinary approach. With the current report we present the case of a 60-year-old lady with metastatic breast cancer and without known preexisting brain metastases, who developed acute phantosmia without other neurological deficits; computed tomography of the brain revealed multiple brain metastases, which were attributed to the malignancy, and for which she was effectively treated with whole brain irradiation and antipsychotic as well as anticonvulsant medications. Furthermore, we underline the value of cooperation between the various specialties that could aid in diagnosis and management of this symptomatology. Phantosmia is an extremely rare symptom in cancer patients, and its appearance should alarm physicians to rapidly investigate a possible progression of disease in the central nervous system. Multidisciplinary approach is needed for the optimal management of these patients.
