“…The surgical approach should be planned depending on the preoperative MRI findings including the size and extent of the lesion, involvement of adjacent vital structures, whether the patient previously had extirpation of the primary tumor, and on the expertise of the surgeon in pelvic or postsacral anatomy. 1,9,21,24,33 The anterior approach allows the surgeon to control the proximal vascular structures and to mobilize the rectum and other internal organs. An anterior or combined approach is usually performed for the lesions above the level of S3, whereas the posterior approach is preferred for the resection of small lesions below the level of S3.…”

“…MRI is more valuable than CT because it is useful in assessing the planes of resection and spatial relationship to surrounding structures and also in determining the most convenient management and imaging procedures for each patient. 9,10,[21][22][23][24] In our series, most of our patients had undergone CT in other clinics due to various reasons. Prior to surgery, the patients without MR contraindications were evaluated with MRI, both for diagnosis and treatment.…”

Due to the rarity and large diversity of the primary retrorectal tumors (RTs), the diagnoses are often difficult and they can be misdiagnosed. We present our experience in light of scarce information available on the clinical manifestations of RTs. The retrospective study included 17 patients diagnosed as RTs between January 2004 and January 2014. Demographic characteristics, length of symptoms, clinical findings, diagnostic methods, evaluations on the treatment procedures and postoperative periods, pathology, complications, and length of hospital stay were recorded. A mean of 1.7 of patients were diagnosed with RTs annually in our hospital. Patients comprised 12 females and 5 males. Pain and discomfort were the most common symptoms at presentation. All the lesions were evaluated by using magnetic resonance imaging (MRI) and computed tomography (CT), and all the patients were treated operatively. Based on the preoperative MRI or CT findings, an anterior approach was performed in 7 patients, a posterior approach in 6 patients, and combined approach in 4 patients. Mean size of tumors was 9.2 6 4.3 cm. Epidermoid cyst (n ¼ 8) was the most common tumor. Except for 1 case of liposarcoma, 16 tumors were confirmed to be of benign nature in histologic examination. Mean length of hospital stay 12.4 6 6.8 days. Retrorectal tumors are heterogeneous and lead to diagnostic difficulties. A high index of clinical suspicion is needed for diagnosis. Preoperative imaging may be helpful in determining the course of treatment. Total excision of a retrorectal tumor may alleviate pressure symptoms and confirm the diagnosis.

ÖZET Periferik sinir k›l›f› kaynakl› schwannomlar, genellikle bafl ve boyunda görülür. Mediastinal ve pelvik yerleflim nadirdir. Retrorektal yerleflimli schwannomlar ise bas›ya ba¤l› semptomlar geliflinceye kadar büyük boyutlara ulaflabilir. Bu yaz›da hipervasküler, büyük boyutlu ve ayn› zamanda, sa¤ adneksiyel kitleyi taklit eden bir retrorektal schwannomun arteryel embolizasyon sonras›nda ç›kar›lmas› sunulmaktad›r.Anahtar Kelimeler: Retrorektal kitle, Schwannoma, Anjiyografi, Embolizasyon ABSTRACT Schwannomas arise from the peripheral nerve sheath and frequently seen in the head and neck region. The mediastinum and pelvic settlement is rare. Retrorectal localized schvannomas may grow quite large before the patient becomes symptomatic due to compresses. In this report we presented excision of hypervasculer, giant retrorectal localized schwannoma mimicking right adnexal mass after arterial embolization.

Retrorectal tumors in adults: Magnetic resonance imaging findings

Abstract: MRI is a helpful technique to define the extent of the retrorectal tumor and its relationship to the surrounding structures, and also to demonstrate possible complications so as to choose the best surgical approach.
