Vacuum-assisted Evacuation (VAEv) of Symptomatic and/or Voluminous Breast Haematomas Following Surgeries and Percutaneous Procedures.

BACKGROUND/AIM: Among postoperative complications in breast surgery, postoperative hematoma is the most common occurrence. While mostly self-limited, in some cases surgical revision is mandatory. Among percutaneous procedures, preliminary studies demonstrated the efficacy of vacuum-assisted breast biopsy (VAB) in evacuating postprocedural breast hematomas. However, no data are available regarding VAB evacuating postoperative breast hematomas. Therefore, the present study aimed to investigate the efficacy of the VAB system in evacuating postoperative and postprocedural hematoma, symptom resolution, and avoidance of surgery. PATIENTS AND METHODS: From January 2016 to January 2020, patients with ≥25 mm symptomatic breast hematomas developed after breast-conserving surgery (BCS) and percutaneous procedures were retrospectively enrolled from a perspective-maintained database. Hematoma maximum diameter, estimated hematoma volume, total procedure time, and visual analog scale (VAS) score before ultrasound (US) vacuum-assisted evacuation (VAEv) were recorded. At one-week VAS score, residual hematoma volume, and complications were recorded. RESULTS: Among 932 BCSs and 618 VAB procedures, a total of 15 late postoperative hematomas were recorded (9 after BCS and 6 after VAB). Preoperative median diameter was 43.00 (35.50-52.50) mm and median volume 12.60 (7.35-18.30) mm3 Regarding VAEv, median time recorded was 25.92 (21.89-36.81) min. At one week, the median hematoma reduction was 83.00% (78.00%-87.5%) with a statistically significant VAS reduction (5.00 vs. 2.00; p>0.001). No surgical treatment was needed and only one case of seroma occurred. CONCLUSION: VAEv represents a promising safe, time and resource-sparing treatment modality for the evacuation of breast hematomas, potentially decreasing the rate of reoperation after surgery.

Artificial Intelligence in Brain Tumor Imaging: A Step toward Personalized Medicine.

The application of artificial intelligence (AI) is accelerating the paradigm shift towards patient-tailored brain tumor management, achieving optimal onco-functional balance for each individual. AI-based models can positively impact different stages of the diagnostic and therapeutic process. Although the histological investigation will remain difficult to replace, in the near future the radiomic approach will allow a complementary, repeatable and non-invasive characterization of the lesion, assisting oncologists and neurosurgeons in selecting the best therapeutic option and the correct molecular target in chemotherapy. AI-driven tools are already playing an important role in surgical planning, delimiting the extent of the lesion (segmentation) and its relationships with the brain structures, thus allowing precision brain surgery as radical as reasonably acceptable to preserve the quality of life. Finally, AI-assisted models allow the prediction of complications, recurrences and therapeutic response, suggesting the most appropriate follow-up. Looking to the future, AI-powered models promise to integrate biochemical and clinical data to stratify risk and direct patients to personalized screening protocols.

Disorder of sex development: a rare case of a boy with an XY karyotype and Magnetic Resonance Imaging findings of hermaphroditism.

Disorders of sexual differentiation are rare congenital conditions in which the chromosomal, anatomic or gonadal sex development is atypical. In some of these patients, chromosomal sex is inconsistent with phenotypic sex; in other cases, the phenotype is not classifiable as either male or female, resulting in a condition known as ambiguous genitalia. These are very complex cases in which diagnostic certainty is not always possible. A multidisciplinary team including geneticists, pediatricians, radiologists is certainly needed to approach these patients. We present the case of an 18-year-old boy with an XY karyotype, ambiguous genitalia, uterus and blind-ending vaginal pouch. The patient had not been previously diagnosed with a disorder of sex development. The patient underwent a panel of genetic analyses and diagnostic imaging investigations. Magnetic resonance imaging was decisive for the identification of the internal genital organs, especially the uterus. At the end of investigations, the patient was diagnosed with 46,XY disorder of sex development. Our purpose is to underline the role of imaging in the diagnosis and management of congenital disorders of sex differentiation.

Coexistence of primary central nervous system lymphoma and primary breast lymphoma: Clinical presentation, imaging features, and treatment management.

The presence of synchronous dual hematological diseases is an uncommon finding. We report an unusual case of coexistence of primary central nervous system lymphoma and primary breast lymphoma without systemic involvement in an immunocompetent patient. To our knowledge a similar case has not yet been reported in the literature. We especially focus on presenting the imaging features, the associated clinical findings and treatment management of each entity, with the aim of raising awareness on these two rare types of lymphomas and the possibility of their coexistence.

Small vascular lesions of the breast diagnosed by magnetic resonance imaging-guided vacuum assisted biopsy: Report of 2 cases.

Vascular lesions of the breast comprise a heterogeneous group that includes a variety of benign, atypical, and malignant lesions. These are a diagnostic challenge given variable clinical, radiological and pathological presentation, especially when they are small and asymptomatic. We present 2 cases of these rare lesions of the breast which were occult to mammographics and ultrasound studies. Both the lesions were detected only on magnetic resonance imaging, most helpful in the diagnosis of these rare tumor. Histopathological examinations following the magnetic resonance guided biopsies, were initially interpreted as negative for breast cancer in both cases. These turned out to be respectively a low grade angiosarcoma and a benign vascular lesion after a new histopathological examination following a larger magnetic resonance guided biopsies performed in light of the radiology-pathology discordance. Although rare, it is important to consider vascular tumours of the breast; radiologists need to be aware such tumors may present non-specific imaging features.

Background Parenchymal Enhancement in Contrast-enhanced Spectral Mammography: A Retrospective Analysis and a Pictorial Review of Clinical Cases.

BACKGROUND/AIM: Despite the popularity of contrast enhanced spectral mammography (CESM), univocal classification of the background parenchymal enhancement (BPE), a bilateral enhancement of the normal breast parenchyma after contrast administration, is lacking. The present study aimed to evaluate the application of BPE Breast Imaging Reporting and Data System Magnetic Resonance (BI-RADS-MR) score for the CESM BPE. Moreover, a pictorial review of four different cases with CESM is provided. PATIENTS AND METHODS: A single-center, retrospective study from a prospectively maintained database of all women undergoing digital mammography (DM) and CESM in our institution between 2016 and 2019. DM and CESM were classified by two experienced radiologists. RESULTS: No statistically significant difference between DM breast density and BPE CESM classification was found. Agreement between readers ranged from substantial to almost perfect. CONCLUSION: BIRADS-RM score for the CESM BPE represents a handy option for radiologists with high inter-reader and DM agreement.
