Penile Abscess Due to Intracavernosal Injection: A Case Report/Intrakavernozal Enjeksiyona Bagli Olusan Penil Apse: Olgu Sunumu.

Introduction

Penile abscess is a rare clinical condition. Symptoms include swelling, pain and local increase in temperature. Among the causes of penile abscess, trauma, foreign body, perianal and perineal abscess drainage, extension of intraabdominal abscess, tuberculosis, priapism, and hematogenous dissemination of periodontal abscess may be listed. Penile abscess may also develop spontaneously (1,2). Diabetic patients are at greater risk for penile abscesses. Staphylococcus aureus, Streptococci, Bacteroides, and Enterococci are the most common microorganisms leading to formation of penile abscess.

Cavernosography, ultrasonography (US), magnetic resonance imaging (MRI) and computed tomography (CT) are useful diagnostic tools (3). Penile abscess can be successfully treated with incision and drainage combined with systemic antibiotics. Successful treatment with aspiration alone has also been described by some authors (1,3,4). We present a case of a paraplegic and parastetic patient who developed a penile abscess due to intracavernosal papaverine injections.

Case Presentation

A 45-year-old patient with spinal cord injury at T12 due to a car accident in 1998 is presented. He had lost both motor and sensory functions in the lower extremities. He was admitted with the complaint of penile swelling. His medical history revealed self-administration of intracavernous papaverine injections for the past 3 years due to erectile dysfunction (ED). At admission, his primary complaint was being unable to apply injections because of swelling. He noticed the swelling 2 months ago, but since he had no pain he did not seek any medical care. On physical examination, severe swelling was detected at the right side of the penis, shifting the corpus to the left side (Figure 1). A mass of 5 cm in size was palpated at the swollen area. In order to differentiate hematoma from abscess, penile MRI was performed. On the right side of the corpus cavernosum, beneath the tunica albuginea, there was an abscess measuring 50x45 mm in size. The abscess caused significant compression and edema in the corpus cavernosum and corpus spongiosum (Figure 1). After intravenous ciprofloxacin treatment was started, the patient was immediately taken into surgical intervention. A circular incision performed at the dorsum of the penis revealed the abscess and 20-25 mL of pus was drained (Figure 2). After pus specimen collection, the abscess region was irrigated with saline. A Miniuac drain was inserted into the abscess area for drainage. S. aureus was isolated and the antibiotic treatment was continued. Following the removal of the drainage catheter, the patient was discharged at the 2nd postoperative day. Six months after the drainage of abscess, it was decided to implant a penile prosthesis in order to treat ED and to avoid further intracavernosal injections. A malleable penile prosthesis was preferred as there could be a risk of complications associated with abscess drainage surgery such as fibrosis and also it was the choice of the patient. Due to tissue fibrosis and adhesions, the process of malleable penile prosthesis implantation was more complicated and took longer than expected (Figure 2).

Written and signed informed consent was obtained from the patient.

Discussion

Penile abscess is a very rare clinical entity. It may occur either in the presence of predisposing factors or spontaneously (3,5). CT and US are good diagnostic tools (2). The management options for penile abscess consist of antibiotic therapy and either open surgical incision and drainage or radiologically guided needle aspiration.

Especially after the treatment of corpus cavernosum abscess, complications such as ED, penile deviation, and penile curvature could develop due to fibrosis and recurrence. Persistent cavernosal abscess may even lead to total penectomy and perineal urethrostomy (6). Penile abscess may be seen at any age. Up to the present, the youngest reported patient is a 24-day-old newborn who developed penile abscess after recurrent priapism (7).

Conditions causing immune suppression, especially diabetes mellitus, are among the most important predisposing factors. Besides these common underlying factors, rare causes such as intracavernous injection may also be listed. Bandi et al. (8) reported an unusual case of multiple retained needles in a 44-year-old man who presented with penile edema after intracavernous self-injection complicated by needle breakage. Tuzel (9) reported a case of a healthy bodybuilder with a corpus cavernosum abscess. In this case, development of the abscess is believed to be facilitated by long-term anabolic androgenic steroid abuse (9).

During the treatment of this rare condition, one could come across with rare complications. Jinga and Iconaru (10) reported a case of a 49-year-old male with penile abscess developed following intracavernous injection which was further complicated with urethrocutaneous fistula 12 weeks after the initial treatment. Kropman et al. (4) reported a successful treatment of a corpus cavernosum abscess with percutaneous aspiration and intravenous antibiotics in a paraplegic man on intracavernous papaverine injection therapy.

Penile abscess is a rare clinical entity. Surgical drainage is the most common mode of treatment but it has risks of ED and penile deviation. Drainage with US or CT guidance should also be considered when needed. Intracavernous self-injection for paraplegic or paraphasic patients with ED should be recommended with serious instructions including all details in order to avoid such complications.
