“…MRI clearly delineates the perianal anatomy and detects complex perianal disease including fistulas which informs preoperative planning . In a recent study of patients with haematological malignancy who were referred for pelvic MRI, 44% had findings consistent with perianal abscess . Similarly, Plumb et al .…”

“…found that MRI frequently detects perianal abscess in patients with haematological malignancy, which is irrespective of the severity of neutropenia. However, haematological malignancy often augments MRI findings, extensive local inflammatory change is more common and fistulous disease is a less common finding compared to immunocompetent patients …”

“…It is challenging to clinically evaluate such patients, as signs are often masked due to the lack of a robust immune response to localize infection and form a clinically recognizable abscess . Additionally, clinical examination is limited as digital rectal examination is often not undertaken due to concerns of breaching mucosal barriers and worsening translocation of bacteria to the region in immunocompromised patients, a concept which is open to debate …”

“…The American Society of Colon and Rectal Surgeons advocates the selected use of computed tomography or magnetic resonance imaging (MRI) to better assess the anatomy and underlying collection . MRI successfully identifies the pathological anatomy of all forms of anorectal disease with an accuracy of up to 90% . Recent evidence suggests that there is a role for MRI in evaluating the perianal area in patients with haematological malignancy, particularly in cases of suspected complex perianal abscess or fistulous disease .…”

Perianal sepsis in neutropaenic patients with haematological malignancy is a common and serious complication while presenting many challenges both diagnostically and therapeutically. This retrospective study found that magnetic resonance imaging was able to successfully detect a drainable collection with up to 80% accuracy despite severe neutropaenia. Both conservative and surgical management strategies were safe, lead to resolution of symptoms and few recurrences.

“…Additionally, endoanal coils and body coils have previously been compared with each other [14] or by surgical correlation. In the literature, it is noteworthy that some of the studies used torso [15][16][17] or spine coils [18]. However, there has been no published literature comparing body coils and superficial coils so far.…”

Purpose: Perianal fistula is an important health problem with devastating morbidity. For diagnosis and prevention of recurrence, perianal fistula imaging (PFI) is crucial. The aim of this study was to investigate if a Flex-M superficial coil images would provide more information than images obtained with a phased-array body coil in PFI. Material and methods:Thirty-one fistulas of 29 patients were prospectively evaluated with magnetic resonance imaging. A phased-array body coil was used in all patients as in routine practice, and sequences with Flex-M coil were also obtained. Afterwards, images were evaluated by two experienced radiologists who were blinded to the patients, coil and also to each other. The site of internal and external openings, and presence or absence of abscess and secondary tracts were recorded. Results:The conspicuity of images was better with the Flex-M coil. Both radiologists saw more internal openings with the Flex-M coil. Cohen's κ value was 0.100 (p = 0.201) for Reader 1 and 0.110 (p = 0.361) for Reader 2 between these two coils. Additionally, numerically more internal/external openings and secondary tracts were seen by both readers. Interobserver variability was not statistically significant, and Cohen's κ values signifyied good concordance between readers. Conclusions:In our study we showed that multichannel superficial phased-array coils improved imaging quality in PFI.We think that Flex-M coil can easily be used in routine clinical practice to gather better images of perianal fistulas.

A variety of tumors involve the anal canal because the anal canal forms the transition between the digestive system and the skin, and this anatomical region is made of a variety of different cells and tissues. Magnetic resonance imaging (MRI) is the modality of choice for diagnosis and local staging of the anal canal and perianal neoplasms. In this pictorial review, we demonstrate the MRI anatomy of the anal canal and perianal region and display the imaging spectrum of tumors in the region along with an overview of its management. Imaging appearances of many tumorlike lesions that can cause diagnostic dilemmas are also demonstrated with pointers to differentiate between them.
