“…In addition, Motosugi et al described the MRI features of ECIAS, especially those of superparamagnetic iron oxide-based MRI; the solid component of the ECIAS showed the same intensity as that of the spleen (39). Based on similar MRI findings, a correct preoperative diagnosis was achieved for another case in our review (17). The similar density on enhanced CT and intensity on MRI between the solid component and the spleen might make it possible to make a correct, preoperative diagnosis of ECIAS.…”

Epidermoid Cyst in an Intrapancreatic Accessory Spleen: Case Report and Literature Review of the Preoperative Imaging Findings

et al. 2016

An epidermoid cyst arising within an intrapancreatic accessory spleen (ECIAS) is rare, and also difficult to correctly diagnose before surgery. It is mostly misdiagnosed as a cystic tumor, such as a mucinous cystic neoplasm or as a solid tumor with cystic degeneration, such as a neuro endocrine tumor. We herein report a case of ECIAS and also perform a literature review of 35 reports of ECIAS. Although the preoperative diagnosis of ECIAS using conventional imaging is relatively difficult to make, careful preoperative examinations of the features on computed tomography and magnetic resonance imaging could lead to a correct preoperative diagnosis of ECIAS which might thereby reduce the number of unnecessary resections.

“…Since 1980, a correct preoperative diagnosis of ECIPAS has been reported in only five cases [15, 21, 26, 32]. These accurate diagnoses were partly based on the smoothness of the cystic inner wall and solid component, a differentiating morphological feature suggestive of a benign tumor [26].…”

Epithelial cyst in an intrapancreatic accessory spleen (ECIPAS) is exceedingly rare with only 57 cases reported since the first publication in 1980. Comprehensive clinical and diagnostic features remain to be clarified. We present a case of ECIPAS in a 21-year-old Philippine woman who was admitted with right upper quadrant abdominal pain. A cystic lesion in the pancreatic tail was discovered and evaluated by computed tomography and magnetic resonance images. Based on clinical and radiological features a solid pseudopapillary neoplasm was suspected. The patient underwent robot-assisted spleen preserving distal pancreatectomy. Pathological evaluation revealed a 26 mm intrapancreatic accessory spleen with a 16 mm cyst, lined by multilayered epithelium in the tail of the pancreas. The postoperative course was uneventful. Differentiating ECIPAS from (pre)malignant cystic pancreatic neoplasms based on clinical and radiological features remains difficult. When typical radiological signs can be combined with scintigraphy using Technetium-99m labelled colloid or Technetium-99m labelled erythrocytes, which can identify the solid component of the lesion as splenic tissue, it should be possible to make the right diagnosis noninvasively. When pancreatectomy is inevitable due to symptoms or patient preference, minimally invasive laparoscopic or robot-assisted spleen preserving distal pancreatectomy should be considered.

“…[4] reported the first case of ECIPAS; and since then 33 articles and 36 patients have been reported in the English language literature (Table 1), suggesting the rarity of the disease. However, the exact incidence of ECIPAS is difficult to determine as over 50% of the cases were incidentally detected [8,9,12,14,15,18,19,22-24], [26,27,30,32,34]. The mean age of the patients was 46.1 years (range 12 to 70 years), with a female preponderance (58.3%) [6,7,10-13,16,17,19-21,24-26,28], [31,33,34,36].…”

Epidermoid cyst of an intrapancreatic accessory spleen: a case report and literature review

et al. 2014

BackgroundAn epidermoid cyst in an intrapancreatic accessory spleen is a rare lesion. Despite advances in radiologic techniques, in most cases it has been diagnosed preoperatively as a possible pancreatic neoplasm.Case presentationHerein, we present a 63-year-old Caucasian woman, diagnosed preoperatively with enhanced-contrast abdominal computed tomography, as having a potential cystic tumor in the tail of the pancreas. The patient underwent a distal pancreatectomy and splenectomy, and the histological examination revealed the presence of an epidermoid cyst of an accessory intrapancreatic spleen.ConclusionsFamiliarity with the imaging features, the clinical presentation and the location of the cyst are important to consider if this rare entity is to be included in the differential diagnosis of cystic neoplasms of the pancreas.
