Association of omphalocele with a patent urachus presenting as a large umbilical cystic mass in a newborn

Patent urachus is a rare congenital abnormality. Since its first description by Cabriolus in 1550, few cases have been reported. A 26-year-old Vietnamese primigravida presented at 20 weeks of gestation for evaluation of a cystic mass in the umbilical cord, which was first discovered at week 13 of pregnancy by ultrasound scan. The cystic mass originated from the root of the umbilical cord, connected to the urinary bladder, and no intestinal contents were enclosed within. Doppler ultrasound assessment showed that the single umbilical artery existed within the normal range. The progression of the umbilical cyst continued to be screened, but the mass disappeared on ultrasound images at 27 weeks of gestation. This led to the consideration of the cyst’s rupture. After 38 gestational weeks, the pregnant woman delivered a 3350g male infant via cesarean section because of an obstructed vaginal labor. The following days, a stream of urine was recorded leaking out from the umbilical mass whenever he cried. Seven weeks after delivery, an open surgical approach was successfully performed. The baby is now 43 months of age, growing and developing normally. Since an allantoic cyst with patent urachus is a rare clinical entity, early discovery, close monitoring and accurate diagnosis through ultrasound in the prenatal period may consequently allow clinicians to have suitable attitudes towards management when the infant is born.

Bladder Prolapse

We report a case of bladder prolapse through a patent urachus in a term male neonate with a large, red, tubular, mucosa lined mass inferior to the umbilical cord. A cystic mass communicating with fetal urinary bladder was detected in an antenatal ultrasound in a 26 years primigravida at 18 and 26 weeks gestation. The cyst disappeared at 35 weeks and a new solid mass was noted at the fetal abdominal wall. After birth a protruded mucosal mass inferior to the umbilical cord was noted. Urethral catherisation confirmed communication with bladder. On the second day of life excision of urachus, repair, reduction of bladder and reconstruction of abdominal wall was performed. The patient voided well and was discharged on ninth day without any complication. DOI: http://dx.doi.org/10.3126/jnps.v34i1.7877 J Nepal Paediatr Soc 2014;34(1):68-70

Abstract Background Mucinous cystadenoma (MC) of the kidney is exceedingly rare. We found 22 similar cases in the literature. These masses are underdiagnosed due to radiologic similarities with simple renal cysts. Case presentation A 66-year-old man with a previous history of hypertension and anxiety was referred to our tertiary clinic with left flank pain. Ultrasound revealed a 60 mm-sized, complex cystic mass with irregular septa in the lower pole of the left kidney (different from last year's sonographic findings of a simple benign cyst with delicate septa). CT scan showed the same results plus calcification. Due to suspected renal cell carcinoma, a radical nephrectomy was performed. Postoperative histopathologic examination revealed a cyst lined by a single layer of columnar mucin-producing cells with small foci of pseudo-stratification, consistent with the MC’s diagnosis. The first follow-up visit showed normal blood pressure without medication and no flank pain and anxiety after a month. Conclusion It is quite challenging to distinguish the primary MC of the kidney from a simple renal cyst based on clinical and imaging findings. The radiologic features of these entities overlap significantly. Thus, complex renal cyst and renal cysts with mural nodules should be followed closely to detect malignancy earlier.

Pancreatic heterotopia (PH) is a common, but typically small (<1 cm), incidental and asymptomatic finding; however, PH should be considered even for large and symptomatic upper gastrointestinal masses. A 27-year-old white woman presented with a 3-week history of burning epigastric pain, nausea, early satiety, and constipation. Physical examination revealed epigastric and right upper quadrant tenderness with normal laboratory workup, but imaging revealed a 5-cm, partly cystic mass arising from the gastric antrum with resulting pyloric stenosis and partial gastric outlet obstruction. Endoscopic ultrasound-guided fine needle aspiration revealed PH – an anomalous pancreatic tissue lying in a nonphysiological site. The patient ultimately underwent a resection and recovered uneventfully, with a complete pathologic examination revealing normal exocrine pancreatic tissue (PH type 2) without malignant transformation. We report a case of heterotopic pancreas manifesting as severe gastric outlet obstruction, in addition to a thorough diagnostic workup and surgical follow-up, in a young adult. Differential diagnoses and features that speak to benignity of a large, symptomatic mass lesion (PH in particular) are discussed.

Mesenteric Cysts

Abstract Introduction/Objective Mesenteric cysts are rare intra-abdominal lesions in adults. However, with the advanced imaging techniques and laparoscopic techniques, they are more often being identified and resected when clinically significant. There is a lack of detailed information in histopathology (except as case reports) since mesentery is generally neglected in our organ-based textbooks. The aim of our study is to highlight the importance of identifying and classifying mesenteric cystic lesions; they are not all that simple. Methods We performed a retrospective search on all mesenteric cysts submitted as excisions in our electronic database from 2013-2019. We classified them as per the de Perrot (PMID: 11053936) classification with modification. Results Our search showed: A. Lymphatic origin-11 (lymphangioma-10, Lymphangioma hamartomatous-1, associated with LAM-0), B. Mesothelial origin-68 (Benign mesothelial cysts-57, multilocular mesothelial cyst-11), C. Enteric origin- 3, D. Urogenital origin (Urachal cyst, mullerian inclusion cyst)-9, E. Mature cystic teratom-2, F. Pseudocyst-12, G. Epithelial cyst (not urogenital)- 11 (a/w LAMN-3, MCN-4, Mucinous cystadenoma-4), H. Associated with carcinoma-2. Case illustration: A 61-year-old male presented with worsening dysphagia, emesis and hiccups. A CT scan showed a 21.2 cm cystic mass with at least one septation (Fig 1). The cyst was resected. On gross pathological examination, the cyst measured 18 cm in greatest dimension with a thick, rough, tan-brown capsule. Microscopic examination showed a fibrous capsule, and cyst wall composed of numerous lymphatic vessels (CD31 positive) and prominent smooth muscle proliferation (Desmin positive). Scattered lymphoid aggregates were also present throughout the cyst wall. No definite epithelial lining was identified and was suspected to have been denuded. HMB-45 immunostain was negative, ruling out association with LAM. The final diagnosis of a Lymphangiomyoma, hamartomatous was rendered. Conclusion Though most of the mesenteric cysts are benign, some of them are significantly important such as Lymphangiomyoma (esp secondary to LAM), MCN, those associated with LAMN etc. and identifying and differentiating from their mimics has distinct clinical implications.

Branchial cleft cysts are congenital anomalies that most commonly arise from a failure of fusion of the second branchial arch during embryonic life. They usually present as a swelling in the lateral side of the neck, below the mandible. In this article, we present a case of a 28-year-old female patient with a right branchial cyst measuring 7 × 6 × 5 cm, who presented with an asymptomatic, rapidly growing mass in the right anterior triangle of the neck that abutted the right external carotid artery, leading to stenosis of the vessel that is preceded by dilatation above the site of compression. She underwent excision of the cystic mass with preservation of the facial nerve and presented no active complaints on follow-up a few weeks postoperatively.

Inflammatory Effect

A huge abdominal cystic lesion with ascites was detected in a male neonate at 31 weeks of gestation. Increasing ascites and the appearance of subcutaneous edema were detected, which caused fetal hydrops. The patient was delivered by emergency cesarean section at 33 weeks of gestation. The birth weight was 2,407 g, and the Apgar score was 8/9 points (1-/5-min values). Breathing at birth was stable, but the patient presented with remarkable abdominal distention due to the ascites. Later, the patient presented with tachypnea, and breathing gradually worsened, so an emergency operation was performed. There were no intraoperative findings within the small intestine, but there was a large amount of ascites and a cystic mass arising from the liver. The patient’s breathing and circulation dynamics could only be stabilized by ascites removal, so only a tumor biopsy was performed. The pathological findings led to the diagnosis of an inflammatory myofibroblastic tumor, and steroids were administered early after surgery for the purpose of an anti-inflammatory effect and tumor shrinkage. The abdominal distention was alleviated, and blood examinations showed a reduced inflammatory response. There was no apparent shrinkage of the tumor, however; thus, radical surgical treatment was performed on day 24. The postoperative course was uneventful, so the patient was discharged on day 36. Seven years after the operation there has been no recurrence or distant metastasis.

Abdominal Pseudocyst

Abstract Background Abdominal cerebrospinal fluid (CSF) pseudocyst is an uncommon but important complication of ventriculoperitoneal (VP) shunts. While individual articles have reported many cases of abdominal CSF pseudocyst following VP shunts, no case of a hemorrhagic abdominal pseudocyst after VP shunts has been reported so far. Case presentation This article reports a 68-year-old woman with a 4-month history of progressive abdominal pain and distention. She denied any additional symptoms. A VP shunt was performed 15 years earlier to treat idiopathic normal pressure hydrocephalus and no other abdominal surgery was performed. Physical examination revealed an elastic palpable mass in her right lower abdomen, which was dull to percussion. Abdominal computed tomography (CT) scan indicated a large cystic collection of homogenous iso-density fluid in the right lower abdominal region with clear margins. The distal segment of the peritoneal shunt catheter was located within the cystic mass. Abdominal CSF pseudocyst was highly suspected as a diagnosis. Laparoscopic cyst drainage with removal of the whole cystic mass was performed, 15-cm cyst which found with thick walls and organized chronic hematic content. No responsible vessel for the cyst hemorrhage was identified. No further shunt revision was placed. Histological examination showed that the cyst wall consisted of outer fibrous tissue and inner granulation tissue without epithelial lining, and the cystic content was chronic hematoma. The patient had an uneventful postoperative course and remained asymptomatic for 8-mo follow-up. Conclusion To the best of our knowledge, this is the first report of hemorrhagic onset in the abdominal pseudocyst following VP shunt. Such special condition can accelerate the appearance of clinical signs of the abdominal pseudocyst after VP shunts, and its mechanisms may be similar to the evolution of subdural effusion into chronic subdural hematoma (CSDH).
