Axillary staging is one of the primary steps in management of Breast cancer patients. Current standard methods including blue dye and radicolloid have limitations and disadvantages. In this study, the feasibility of visualization of lymph node pathways and localization of SLN with the help of CEUS was assessed. 50 patients with early breast cancer diagnosis underwent CEUS and wire localization, methylenblue dye, and isotope scan methods for SLN detection. The pathology findings of the wired SLN were compared with those obtained from, methylenblue dye, and isotope scan methods. Lymph node wiring was successfully performed in 48 patients.Radio-isotope technique detected SLN in all 50 patients while blue-dye succeeded in 48. Sensitivity of CEUS to detect SLN compared with radio-isotope and blue dye methods was 96 % and 100 %, respectively. Considering costs and facilities required to perform radio-isotope technique and complications of blue dye we may accept CEUS with the help of micro-bubble contrasts as a viable alternative. However, more studies with larger sample volumes, using various drugs, and including non-selective population are warranted to better clarify feasibility and accuracy of this technique in comparison with current methods.

Metastatic tumors involving the small bowel are much more common than primary neoplasms. The most common metastases to the small intestine are those arising from other intra-abdominal organs. Metastases from extra-abdominal tumors are rare but may be found in patients with adenocarcinoma of the breast and carcinoma of the lung. Cutaneous melanoma is the most common extra-abdominal source involving the small intestine, with involvement of the small intestine noted in more than half of the patients dying from malignant melanoma [1]. While intestinal metastasis from sarcoma has been described, this is an extremely rare occurrence especially from a rare malignant sarcoma of cardiac origin. The dismal prognosis of cardiac sarcomas results from extensive local invasion at presentation or distant metastasis. Metastasis to the small bowel may cause obstruction, bleeding, or intussusception in which the diagnosis may be delayed because of rarity of the condition and mild and vague abdominal symptoms at early presentation. In this report, a 35 year old woman a known case of cardiac fibrosarcoma was admitted to the emergency ward with abdominal pain and distention, bloody diarrhea, and recurrent nausea and vomiting. Jejuno-jejunal invagination was diagnosed at laparotomy along with tumoral involvement of the left ovary. Histopathological study showed that there was a fibrosarcoma compatible with the earlier diagnosis of primary cardiac tumor. We have described some aspects of diagnosis and treatment of this rare cause of intestinal intussusception.

Neo-adjuvant brachytherapy (NBT) for oesophageal cancer is under rapid development in recent years and more reports are required to elucidate its complications and drawbacks. Here, we report a case treated for NBT whose oesophagus was perforated during the procedure and mention necessary precautions to avoid it. A 73 year old male whose upper gastrointestinal endoscopy showed a lesion extending from 29 cm to 33 cm of the incisors with a histology of poorly differentiated squamous cell carcinoma, without metastases. Endoscopic ultrasonography diagnosed a T3 N0 grade tumour. He was selected for NBT and neo-adjuvant chemotherapy. The patient received 5 Gy in the first session of NBT, but in the second session before receiving the same dosage his control chest X-ray showed the tip of the catheter to be out of the oesophageal tract. After confirmation of the perforation by Gastrografin, we performed total oesophagectomy combined with a gastric pull-up procedure. To our best knowledge, our case is the first reported complication related to the direct effect of the catheter and tissue manipulation rather than the radiation beam. Weakness in the oesophageal wall due to tumour involvement makes it prone to perforation by any rigid catheter.
