Abstract Background The accessory spleen has no anatomical or vascular relationship with the normal spleen, The tissue structure and physiological function of the accessory spleen are the same as those of the normal spleen, which usually locate in the splenic hilum and the tail of the pancreas. The aims of this manuscript are to present a rare case of the gastric accessory spleen and a review of the literature. Case presentation A 19-year-old male patient was sent to the emergency department with stomach bleeding after drinking alcohol. The computed tomographic scan showed a 1.2 cm × 1.7 cm mass at the lesser curvature of the gastric fundus. Gastrointestinal endoscopy displayed a submucosal elevated lesion on the gastric fundus, and gastrectomy was performed. Postoperative pathological examination proved an accessory spleen in the stomach. The postoperative course was uneventful, and the patient was discharged on the 6th day after the surgery. Conclusions The accessory spleen at the fundus of stomach is extremely rare, especially in this case, which is accompanied by acute gastric bleeding, and it is difficult to diagnosis before operation. Many literatures reported that it was misdiagnosis as tumor, so it is necessary to diagnose accessory spleen correctly.

AbstractTo evaluate whether quantitative PET parameters of motion-corrected 68Ga-DOTATATE PET/CT can differentiate between intrapancreatic accessory spleens (IPAS) and pancreatic neuroendocrine tumor (pNET). A total of 498 consecutive patients with neuroendocrine tumors (NET) who underwent 68Ga-DOTATATE PET/CT between March 2017 and July 2019 were retrospectively analyzed. Subjects with accessory spleens (n = 43, thereof 7 IPAS) and pNET (n = 9) were included, resulting in a total of 45 scans. PET images were reconstructed using ordered-subsets expectation maximization (OSEM) and a fully convergent iterative image reconstruction algorithm with β-values of 1000 (BSREM1000). A data-driven gating (DDG) technique (MOTIONFREE, GE Healthcare) was applied to extract respiratory triggers and use them for PET motion correction within both reconstructions. PET parameters among different samples were compared using non-parametric tests. Receiver operating characteristics (ROC) analyzed the ability of PET parameters to differentiate IPAS and pNETs. SUVmax was able to distinguish pNET from accessory spleens and IPAs in BSREM1000 reconstructions (p < 0.05). This result was more reliable using DDG-based motion correction (p < 0.003) and was achieved in both OSEM and BSREM1000 reconstructions. For differentiating accessory spleens and pNETs with specificity 100%, the ROC analysis yielded an AUC of 0.742 (sensitivity 56%)/0.765 (sensitivity 56%)/0.846 (sensitivity 62%)/0.840 (sensitivity 63%) for SUVmax 36.7/41.9/36.9/41.7 in OSEM/BSREM1000/OSEM + DDG/BSREM1000 + DDG, respectively. BSREM1000 + DDG can accurately differentiate pNET from accessory spleen. Both BSREM1000 and DDG lead to a significant SUV increase compared to OSEM and non-motion-corrected data.

Dear Sir, I take the liberty to remit you an account of the delivery of a very curious acephalous monster, accompanied with a short description of its anatomical structure. If, after a perusal of it, you should apprehend it may be acceptable to the Royal Society, I beg that you will do me the honour to lay it before them. Mrs. Brackett, of Clerkenwell Close, aged twenty-three years, was, at the end of her first pregnancy, by a natural labour, delivered of a perfect female child, on Friday the 8th of October, 1773, at seven o'clock in the morning. The attending midwife, Mrs. Ayres, soon perceived by the abdominal tumour that there was another child. After waiting about three hours, a flooding came on; but without pain, or any advancement of the second delivery. The hæmorrhage producing faintness, debility, and danger, the attendants and midwife were alarmed, and I was sent for. When I came, I found her in the situation above described; and therefore thought it my duty to accomplish the remaining part of the labour, as soon as I could, consistently with the safety of the mother.

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.
