INTRODUCION

In February 2019, 73-year-old woman reported with right breast and enlarged lymph nodes in right axilla. Core-needle biopsy of the tumour was performed, and it confirmed the diagnosis of invasive breast carcer NST G2, oestrogen-dependent, HER2-negative; ki 67 was 2%. Imaging showed metastases in the lungs and liver, and numerous osteolytic lesions in the bones with vertebral body fractures (Th6-Th12) (Fig. 1 A–C). The family history was negative; the patient had been treated for many years due to hypertension and ascending aortic aneurysm. A few years earlier she had not consented to surgical treatment of the aneurysm; she was under constant cardiac care, and her general condition was stable (ECOG 1).

MATERIAL AND METHODS

The patient was qualified for ribociclib therapy in combination with letrozole and zoledronic acid. She received palliative irradiation of Th6-Th8 and Th12-L2, which alleviated her pain; painkillers were also included. The treatment stabilized the cancer and her general condition by February 2020. In a PET scan performed at the time previously unobserved lymph nodes in the mediastinum and liver recess were described; the lesions were ambiguous (Fig. 1 D, F). In July 2020, progression was seen in suspicious lymph nodes (Fig. 1 G–I). The patient reported progressive weakness and deterioration of appetite. CDK4/6 inhibitor and letrozole were discontinued, tamoxifen was included, and zoledronic acid therapy was continued.

RESULTS

After the treatment change there was a rapid deterioration of the patient’s general condition; she was drowsy and confused. The spread of cancer to the central nervous system (CNS) was suspected. The patient’s husband and daughter (physicians) were diagnosed with coronavirus infection. Husband had a fever and cough, and the daughter was completely asymptomatic. The patient’s test was also positive; thus, she was referred to the infectious diseases ward. The dominant symptom was progressive weakness, followed by neurological abnormalities: confusion, dizziness, and disinhibition reaction. Her general condition did not allow CNS imaging diagnostics. During hospitalization the patient was treated symptomatically, but her general condition did not improve. The patient died after 16 days of hospitalization. Probably the patient’s death was due to heart failure, but no autopsy was performed.

DISCUSSION

Breast cancer is the most common cancer in women worldwide. Thanks to modern therapies, metastatic breast cancer can be treated as a chronic disease [1]. Literature data suggest that the mortality of coronavirus-infected breast cancer patients is more dependent on coexisting diseases and age (> 70 years of age, hypertension) than the anticancer treatment [2]. The diagnosis of SARS-CoV2 infection in patients without classical symptoms is challenging, which may delay treatment. In the course of coronavirus infection, neurological symptoms may appear, the most common being anosmia and ageusia. Less frequent are strokes, Guillain-Barre syndrome, and encephalitis. According to the literature, encephalopathy appears in 7–69% of patients, and the incidence increases with the severity of coronavirus infection [3].

CONCLUSIONS

In the presented case, the symptoms of SARS-CoV2 infection mimicked metastatic spread to the CNS. Confirmed SARS-CoV2 infections in the family led to the diagnosis of this infection in the patient. Special attention should be paid to cancer patients with comorbidities, especially during anticancer therapy, because symptoms of coronavirus infection may be non-specific, and an undiscovered infection can be fatal. The authors declare no conflict of interest.
