Uncommon Tumor

Benign cystic mesothelioma (BCM) is an uncommon tumor. A 9-year-old girl presented with acute abdominal pain and vomiting for the last 24 hours. Ultrasound abdomen and contrast enhanced CT scan were suggestive of cystic lesion. At laparotomy, a cystic mass arising from the peritoneum was found, which was excised completely. On histopathological examination it was diagnosed as benign mesothelioma.

AbstractOur objective was to investigate the feasibility of deep learning-based synthetic contrast-enhanced CT (DL-SCE-CT) from nonenhanced CT (NECT) in patients who visited the emergency department (ED) with acute abdominal pain (AAP). We trained an algorithm generating DL-SCE-CT using NECT with paired precontrast/postcontrast images. For clinical application, 353 patients from three institutions who visited the ED with AAP were included. Six reviewers (experienced radiologists, ER1-3; training radiologists, TR1-3) made diagnostic and disposition decisions using NECT alone and then with NECT and DL-SCE-CT together. The radiologists’ confidence in decisions was graded using a 5-point scale. The diagnostic accuracy using DL-SCE-CT improved in three radiologists (50%, P = 0.023, 0.012, < 0.001, especially in 2/3 of TRs). The confidence of diagnosis and disposition improved significantly in five radiologists (83.3%, P < 0.001). Particularly, in subgroups with underlying malignancy and miscellaneous medical conditions (MMCs) and in CT-negative cases, more radiologists reported increased confidence in diagnosis (83.3% [5/6], 100.0% [6/6], and 83.3% [5/6], respectively) and disposition (66.7% [4/6], 83.3% [5/6] and 100% [6/6], respectively). In conclusion, DL-SCE-CT enhances the accuracy and confidence of diagnosis and disposition regarding patients with AAP in the ED, especially for less experienced radiologists, in CT-negative cases, and in certain disease subgroups with underlying malignancy and MMCs.

Lobular capillary haemangioma, also known as pyogenic granuloma, is a benign vascular tumour that usually originates in the skin and mucosal membrane. It sometimes derives from the lumen of a vein and the clinical presentations are various and non-specific. A 72-year-old woman complained of a sensation of pressure in her left neck for 1 month when cooking. Her left cephalic vein was enlarged with no signs of oedema, and cervical ultrasound revealed a space-occupying lesion in the left subclavian vein. Contrast-enhanced CT and MRI revealed an intravascular tumour. This tumour was removed with operation, and histopathological examination revealed intravascular capillary haemangioma. Intravascular lobular capillary haemangioma is a rare condition that occurs in the veins of the neck and upper extremities. Intravascular tumours could cause a unique symptom, such as neck discomfort associated with neck anteflexion.

Rare Malignancy

Mixed adenocarcinoma with neuroendocrine tumour of pancreas has been reported infrequently and consists of both epithelial and neuroendocrine component. We encountered an 81-year-old male patient who presented with clinical features of painful progressive jaundice for 1 month. Contrast-enhanced CT abdomen reported a mass in the pancreatic head with dilated common bile duct and pancreatic duct. He underwent pancreatoduodenectomy and histopathological examination revealed two different tumours: ductal adenocarcinoma admixed with neuroendocrine tumour of pancreas. He received adjuvant chemotherapy, and at the end of 1-year follow-up, he has no recurrence. Here, we reported this rare malignancy of pancreas for which pancreatoduodenectomy was done and diagnosed on histopathology with immunohistochemistry.

Intraluminal Migration

ABSTRACTRetained surgical mops following surgery is an avoidable but serious complication. They are seldom reported because of medicolegal implications but clinicians need to be aware about varied presentations of this entity to avoid unnecessary morbidity. We report a case of a 28-year-old woman who presented with chronic diarrhea and lower abdominal pain due to intraluminal migration of the surgical mop into the sigmoid colon 6 months after myomectomy of the uterus. The possibility of gossypiboma was suggested by the contrast-enhanced CT scan of the abdomen. Flexible sigmoidosocpy showed the remnants of the mop inside the lumen of the sigmoid colon. She underwent laparotomy and removal of the surgical mop and became completely asymptomatic. Though gossypiboma is rare clinicians should keep it in mind in patients who had undergone laparotomy previously. (J Dig Endosc2011;2(1):22-24)

Functioning Kidney

Spontaneous rupture of renal pelvis (SRRP) is a rare condition resulting in an extravasation of urine into retroperitoneal space. Due to the uncharacteristic symptoms, often mimicking renal colic, its diagnosis may be complicated. Herein, we report a case of a 73-year-old male with a solitary functioning kidney who presented with malaise and right-sided abdominal pain, rapidly followed by anuria. Laboratory tests showed the signs of AKI. Contrast-enhanced CT performed soon after the admission showed nonspecific abnormalities in the right middle abdomen suspected to be either inflammatory infiltration or surgical scarring. Symptomatic treatment was started, and an acute hemodialysis treatment was commenced. After a temporal improvement, the patient’s general condition worsened significantly, with exacerbated pain and massive increase in plasma creatinine. A second contrast-enhanced CT was performed with an addition of urography phase, revealing the extravasation of the contrast media in the location suggesting the rupture of the renal pelvis. The patient was treated successfully by the placement of a double-J ureteral stent into the ureter. Usually, a clear etiology of SRRP can be determined, that is, urinary tract obstruction, but in this case, we could not find a definite cause. It is important to remember that in the presence of a nonspecific abdominal pain and laboratory signs of AKI, a rare cause like SRRP should be taken into consideration. Performing a contrast CT scan with urography phase can save time in establishing a diagnosis and enable immediate urological intervention.

Time Of Admission

A 22-year-old young woman presented with fever, lower abdominal pain and vomiting for 20 days. She had persistent fever and abdominal pain. Fever panel was negative. Clinical features were suggestive of subacute small bowel obstruction. Contrast-enhanced CT abdomen showed thickening of distal ileum, ileocaecal junction and caecum with conglomerate necrotic nodal mass in the ileocolic mesentry along with a lesion in the tail of pancreas. Patient was discussed with multidisciplinary team and decided to undergo a single-stage procedure after adequate nutritional optimisation. During optimisation, she underwent acute obstruction and hence taken up for emergency laparotomy proceeded to right haemicolectomy with distal pancreatectomy and splenectomy 4 weeks after the time of admission. Histopathology showed ileocaecal tuberculosis and solid pseudopapillary tumour with margins free of tumour. Approach of obstructed ileocaecal tuberculosis in the setting of incidental diagnosis of solid pseudopapillary tumour of pancreas in a moribund patient was challenging.

Hepatobiliary cystadenoma is a rare benign cystic tumor of the liver. These are predominantly located in right hepatic lobe. A 45 year old female presented with abdominal pain, epigastric discomfort, fever and vomiting. On radiological evaluation USG showed large multiloculated cystic mass in right lobe of liver. Contrast Enhanced CT examination exhibited exophytically growing multiloculated cytic lesion with differential content and peripheral capsular and central enhancement with imaging diagnosis of hydatid cyst was given. The surgical excision of hepatic cyst was done. On histopathology reported as mucinous cystadenoma of liver with mesenchymal stroma. We are presenting this case for its rarity, clinical, radiological and histopathological findings.

Twenty-seven cystic renal cell carcinomas (RCC) in 23 patients were analyzed radiologically and histologically. They were classified into 4 histopathologic growth patterns: a) multilocular (n = 15, 9 with macrocystic and 6 with microcystic components); b) unilocular (n = 3); c) cystic necrosis (n = 9); and d) tumors originating in the wall of a simple cyst (n = 0). Macrocystic multilocular RCC showed multiloculated configuration on ultrasound and contrast enhanced CT. Angiography revealed neovascularity peripherally or within the tumor (7/9 tumors). Microcystic multilocular RCC did not fulfill the criterion for a cystic mass on ultrasound: they were irregularly hyperechoic. There was little enhancement on postcontrast CT and only slight neovascularity on angiography. Unilocular RCC showed a cystic mass with an irregular wall or mural nodules on ultrasound and contrast enhanced CT. Necrotic RCC showed various sonographic findings from anechoic to irregular echoic. The appearance on CT varied from cystic with mural nodules to a multiloculated or irregular architecture. Neovascularity was seen in the periphery in 8 of 9 tumors. Clinically, this type seemed to be the most aggressive.

Adrenal Infarction

Adrenal infarction is a rare event, especially in pregnancy. The diagnosis is challenging because patients present with acute abdomen and initial workup are usually unrevealing. We present a case of unilateral adrenal infarction in a pregnant young woman without any other causes of thrombophilia, who presented with acute abdominal pain and an unremarkable initial workup. MRI and contrast-enhanced CT scan revealed a non-haemorrhagic infarct of the right adrenal gland. Our case highlights the importance of considering this rare diagnosis in the differential for a pregnant woman with acute abdomen without any obvious surgical cause.
