a b s t r a c t Ventriculoperitoneal (VP) shunt malfunctions are common and can result in significant consequences for patients. Despite the prevalence of breast augmentation surgery and breast surgery for other pathologies, few breast related VP shunt complications have been reported. A 54-year-old woman with hydrocephalus post-subarachnoid hemorrhage returned 1 month after VP shunt placement complaining of painful unilateral breast enlargement. After investigation, it was determined that the distal VP shunt catheter had migrated from the peritoneal cavity into the breast and wrapped around her breast implant. The breast enlargement was the result of cerebrospinal fluid retention. We detail this unusual case and review all breast related VP shunt complications reported in the literature. To avoid breast related complications related to VP shunt procedures, it is important to illicit pre-procedural history regarding breast implants, evade indwelling implants during catheter tunneling and carefully securing the abdominal catheter to prevent retrograde catheter migration to the breast.

1. Background The ventriculoperitoneal (VP) shunt is a widely used treatment for hydrocephalus. Shunt malfunctions such as obstruction and disconnection are common; however, migration of the distal catheter out of the abdomen is less frequent. We report a unique case of distal VP shunt catheter migration out of the peritoneal cavity and into the breast. Although rare, surgeons should pay careful attention to catheter tunneling and securing the distal catheter at the abdominal wall, particularly in patients with breast implants, in order to avoid breast related VP shunt complications.
to the abdominal fascia and prevent re-herniation out the abdomen. Finally, an 18 gauge needle was placed into the breast medial to the saline implant and 400 cc of retained cerebrospinal fluid (CSF) was drained. Fluid analysis revealed no signs of infection and the cultures were negative. Post-operative radiographs confirmed the distal catheter was intact throughout its course in the chest and ended in the peritoneal cavity (Fig. 1F). The saline implant had not been perforated. The patient’s breast discomfort resolved and the cosmetic appearance of the breast returned to its usual size and appearance. At 2 week follow-up she remained asymptomatic.
3. Discussion 2. Clinical presentation A 54-year-old woman presented with Fisher Grade 3 aneurysmal subarachnoid hemorrhage and hydrocephalus (Fig. 1A). Her past medical history was significant for rheumatoid arthritis and saline implant breast augmentation 20 years prior. A right external ventricular drain (EVD) was placed and her ruptured anterior communicating artery aneurysm was coiled. After failing two EVD clamping trials, a left sided VP shunt was placed without complication. The patient did well clinically and was discharged. One month later, the patient returned to clinic complaining of left breast pain and swelling. Physical examination revealed an enlarged, firm, and tender left breast with no signs of infection or nipple discharge. A CT scan of the brain showed no ventriculomegaly. Shunt series radiographs revealed the proximal shunt catheter was in good position, but the distal VP shunt tubing was displaced from the abdomen and coiled inside the left breast, adjacent to the saline implant (Fig. 1B). A shunt revision was performed (Fig. 1C–E). Through a new incision the previous catheter was removed and a new distal catheter was tunneled in a more medial trajectory than the previous operation to avoid the breast. An encircling absorbable drain retention stitch was used to secure the new distal catheter ⇑ Corresponding author. Tel.: +1 305 243 4675; fax: +1 305 243 3337. E-mail address:

Distal VP shunt catheters are known to migrate into unusual areas of the body, such as the lungs [1], heart [2], neck [3], and scrotum [4]. We report a case of distal VP shunt tubing migration from the peritoneal cavity to the previously operated left breast resulting in breast CSF pseudocyst and discomfort. A review of the literature found 21 previously reported cases of breast related VP shunt complications and 11 cases of distal catheter migration into the breast (Table 1). Including our patient, reported breast-related shunt complications comprise of 13.6% (3/ 22) shunt fractures and local leaks with breast pseudocyst [5–8], 9% (2/22) breast carcinoma invasion, 9% (2/22) breast implant perforation, 13.6% (3/22) retrograde CSF tracking from abdomen [10], and 50% (11/22) distal catheter migration into the breast [5,9]. The median age of diagnosis was 50 years (range: 13 to 88 years), and the mean time from surgery to presentation was 23.3 weeks (range: 1 week to 3 years). Ipsilateral breast swelling was the most common complaint (60%) and nipple CSF discharge, or ‘‘CSF galactorrhea,’’ was reported in six patients (27%) [10]. Ten of the 22 patients suffering breast related shunt complications had breast implants; nine had implants in place at the time of VP shunt placement, but two patients with a shunt had a complication after a breast augmentation procedure [9]. Of the 11 cases of catheter migration into the breast, eight of the patients also had breast implants and 91% (10/11) presented with breast CSF retention. The mechanism of catheter migration into the breast is unknown, but it is presumed to be the result of intra-abdominal

pressure elevations (such as cough, strain, exercise) exerting a positive force on the abdominal catheter. In the setting of a less than optimal multilayer abdominal closure or inadequate anchoring of the peritoneal catheter, the catheter can be pushed retrograde from the abdomen into a potential space in the breast. In the specific case of a pre-pectoral breast implant, we speculate that the presence of a fibrotic capsule around the implant may exert a tethering proximal pulling effect of the tubing and provide a potential space for migration.
4. Conclusion This case report represents a cautionary tale. In five of the 10 patients with implants and breast related VP shunt complications, the physician was unaware that the patient had breast implants prior to surgery [6,9]; therefore, obtaining a pre-operative history of breast augmentation is important to avoid breast implant related complications. In patients with known implants, tunneling should be performed carefully to avoid implant perforation, and

the distal shunt catheter should be secured meticulously to avoid retrograde catheter migration. Finally, female patients with and without breast implants should be advised of potential breast related complications that can occur with VP shunts, including the hazards of future breast augmentation procedures.

a b s t r a c t Invasive central nervous system aspergillosis is a rare form of fungal infection that presents most commonly in immunocompromised individuals. There have been multiple previous reports of aspergillus vertebral osteomyelitis and spinal epidural aspergillus abscess; however to our knowledge there are no reports of intramedullary aspergillus infection. We present a 19-year-old woman with active acute lymphoblastic leukemia who presented with several weeks of fevers and bilateral lower extremity weakness. She was found to have an intramedullary aspergillus abscess at T12–L1 resulting from adjacent vertebral osteomyelitis and underwent surgical debridement with ultra-sound guided aspiration and aggressive intravenous voriconazole therapy. To our knowledge this is the first reported case of spinal aspergillosis invading the intramedullary cavity. Though rare, this entity should be included in the differential for immunocompromised patients presenting with fevers and neurologic deficit. Early recognition with aggressive neurosurgical intervention and antifungal therapy may improve outcomes in future cases. Ó 2014 Elsevier Ltd. All rights reserved.

patients [1–3]. Intracranial disease occurs most commonly and is rapidly fatal without treatment [1]. Spinal aspergillosis is more indolent, but far rarer and typically develops from contiguous vertebral osteomyelitis or systemic infection [3]. Reports in the literature have catalogued multiple patients with epidural or intradural extramedullary abscesses, but never with intramedullary involvement [2,3]. Here we describe to our knowledge the first
