Table 1. Cases of breast cancer arising in the VP shunt pathway (n=7).
| Author | Age (years) | Chief concern | Tumor diameter (cm) | Distance between shunt and tumor (cm) | Diagnostic procedure | Medical treatment | Pathological result | Progress |
|---|---|---|---|---|---|---|---|---|
| Keshtgar et al []6 | 52 | Right breast mass | 5 | No description (away) | No description | Mastectomy. VP shunt was preserved | No description | Good postoperative course |
| Lee et al []7 | 88 | Right breast induration | 1.7 | 0 | No description | Lumpectomy. VP shunt was preserved | IDC, luminal type | No description |
| Roka et al []8 | 70 | headache | 8 | 0 | FNAC | Mastectomy+ALND. VP shunt pathway was rerouted. | IDC | 2 months after surgery, good progress |
| Jain et al []9 | 67 | Right breast mass | 1.3 | 0 | FNAC | Partial mastectomy +SLNB. VP shunt pathway was rerouted | IDC, luminal type | Good progress |
| Copeland-Halperin et al []10 | 74 | No description | No description | No description (away) | No description | Partial mastectomy + SLNB. VP shunt was preserved. | IDC, luminal A | 3 years after surgery, intramammary recurrence |
| Kamei et al []11 | 84 | Left breast mass | 3 | 0 | FNAC | No treatment | No description | Died 10 months after diagnosis |
| Our case | 86 | Right breast mass | 3.6 | 0 | CNB | Mastectomy. VP shunt pathway was rerouted | IDC, triple-negative | 4 months after surgery, good progress |
| FNAC – fine-needle aspiration cytology; CNB – core-needle biopsy; SLNB – sentinel lymph node biopsy; ALND – axillary lymph node dissection; IDC – invasive ductal carcinoma. | ||||||||
