A 12 yr old castrated male Yorkshire terrier was presented with a history of an inoperable pheochromocytoma. Physical examination revealed a large, midabdominal mass. Neurologic examination was normal at presentation. An abdominal computed tomography scan revealed a 215 cm3 mass in the region of the right kidney. Forty-eight hours after IV injection of 370 megabecquerels (MBq, equivalent to10 millicuries [mCi]) of metaiodobenzylguanidine labeled with radioactive iodine ([131I]MIBG), standard planar scintigraphy was performed. A diffuse area of moderate uptake was noted in the midabdominal region. The dog experienced stable disease for 1.5 mo after injection based on a follow-up computed tomography (CT) scan; however, 5 mo after injection, repeat CT imaging revealed progression of the tumor, and a second IV injection of 370 MBq (10 mCi) of [131I]MIBG was administered. The dog died 3 wk after the second injection as a result of gastrointestinal blood loss that was believed to be caused by compression-induced bowel ischemia by the mass. A full necropsy was not performed, but the mass was removed for histologic evaluation, which confirmed the diagnosis of pheochromocytoma. This report is the first to document the treatment of canine pheochromocytoma using [131I]MIBG.

A 37-year-old woman, Para 5+0 presented with a 1 year history of recurrent convulsions and progressive weakness of the right side of the body. She had been treated for postpartum eclampsia in her last delivery but symptoms recurred 3 months later. Evaluation including computerized tomography scan of the brain suggested a parieto-temporal meningioma, which was completely excised at craniotomy. Histology confirmed this to be a meningioma. The patient was well at 8 months of follow up. The growth of meningiomas may increase during pregnancy due to presence of receptors for progestational hormones in the tumour and the meningioma may become symptomatic in pregnancy, presenting as eclampsia. Close follow up of patients with eclampsia is necessary to identify neurological features that may lead to a diagnosis of meningioma. Early diagnosis is essential if a good outcome is to be ensured.

Demostrar la importancia de la Tomografía computarizada (TC) y Resonancia Magnética (RM) en el diagnóstico, extensión y seguimiento de los pacientes con papiloma invertido (PI). Paciente femenino de 64 años, con antecedentes de sinusitis alérgica recurrente, que consulta por obstrucción nasal bilateral a predominio izquierdo, asociada a rinorrea purulenta y rinolalia de cinco meses de evolución. Se le realiza TC y RM de Macizo Cráneo facial (MCF). La TC demuestra formación de densidad de partes blandas ubicada en fosa nasal y seno maxilar derecho que se extiende hacia celdillas etmoidales bilaterales, seno frontal y seno esfenoidal derecho. La RM evidencia lesión expansiva sólida ubicada sobre seno maxilar derecho, que se extiende excavando la pared interna del mismo hacia fosa nasal homolateral. El PI es una neoplasia nasal que se caracteriza por su crecimiento invertido hacia el estroma. Es un tumor benigno que presenta una incidencia anual del 1 % promedio por cada 100.000 habitantes. La TC es el método imagenológico de elección para el diagnóstico de PI, siendo también útil en la valoración de la extensión en la fase preoperatoria. El diagnóstico de certeza lo determina la histopatología. La RM representa un método de gran utilidad en el seguimiento postoperatorio. AbstractDemonstrating the importance of Computed Tomography (CT) and Magnetic Resonance (MRI) in the diagnosis, extension and follow-up of patients with inverted papilloma (IP) of a 64-year-old female patient with a history of recurrent allergic sinusitis who consults for bilateral nasal obstruction and left predominance associated with purulent rhinorrhea and rhinolalia of five months of evolution. CT and MRI of CranioFacial Massif (CFM) were performed. CT demonstrated soft tissue density formation located in the nasal fossa and right maxillary sinus extending to bilateral ethmoidal cells, frontal sinus and right sphenoid sinus. MRI showed solid expansive lesion located on the right maxillary sinus, extending through its inner wall to the homolateral nasal fossa. IP is a nasal neoplasm that is characterized by its inverse growth towards the stroma. It is a benign tumor that presents an annual incidence of 1% average per 100,000 inhabitants. CT is the imaging method of choice for the diagnosis of IP, and it is also useful in assessing extension in the preoperative phase. A thorough diagnosis is determined by histopathology. MRI represents a very useful method in postoperative follow-up.

Recurrent urachal adenocarcinomas are rare. It is commonly associated with poor prognosis. A 51-year-old woman underwent a partial cystectomy for urachal cancer in 2014. She was well throughout follow-up with annual cystoscopies. She presented with a 1-month history of rapidly progressive suprapubic mass and hematuria. A contrasted computed tomography scan of the thorax, abdomen and pelvis showed a large mixed solid cystic tumour at the right lumbar region, suprapubic area and also at the pouch of Douglas. She refused surgical extirpation and now on chemotherapy. Urachal adenocarcinoma is rare, and resection is commonly advocated; usually, no standard adjuvant therapy is advocated. Recurrent cancers represent a management dilemma, and no standard follow-up protocols exist. Bangladesh Journal of Medical Science Vol.20(4) 2021 p.911-913

Objective In this case report, we aimed to discuss a septic pelvic thromboembophlebitis (SPT) case detected 20 days later who had the previous history of cesarean section and had an intrauterine stillbirth vaginally at 30 weeks of gestation. Case(s) A 24-year old patient, who admitted to the emergency service with the complaints of fever and pain in the lower right abdomen and was reported to have a 4 cm formation consistent with thrombus on the right ovarian vein wall in the computed tomography (ST), was hospitalized for follow-up and treatment. The patient whose thrombus showed remission in the check-up tomography scan after the broad-spectrum antibiotherapy and anticoagulant treatment was discharged on the 10th day. The treatment of the patient who did not develop any complication in the follow-ups was completed with recover. Conclusion In conclusion, SPT is a complication which is seen rarely in both obstetric and gynecologic practices. SPT is a disease which may lead to fatal outcomes by late diagnosis but satisfying results with early diagnosis. Abdominal pain and fever symptoms should come to mind in all cases after delivery or operation.

Abstract Background Diaphragmatic hernias may occur as either congenital or acquired. The most important cause of acquired diaphragmatic hernias is trauma, and the trauma can be due to blunt or penetrating injury. Diaphragmatic hernia may rarely be seen after thoracoabdominal trauma. Case presentation A 54-year-old Turkish male patient admitted to the emergency department with abdominal pain and dyspnea ongoing for 2 days. He had general abdominal tenderness in all quadrants. He had a history of a stabbing incident in his left subcostal region 3 months ago without any pathological findings in thoracoabdominal computed tomography scan. New thoracoabdominal computed tomography showed a diaphragmatic hernia and fluid in the hernia sac. Due to respiratory distress and general abdominal tenderness, the decision to perform an emergency laparotomy was made. There was a 6 cm defect in the diaphragm. There were also necrotic fluids and stool in the hernia sac in the thorax colon resection, and an anastomosis was performed. The defect in the diaphragm was sutured. The oral regimen was started, and when it was tolerated, the regimen was gradually increased. The patient was discharged on the postoperative 11th day. Conclusions Acquired diaphragmatic hernia may be asymptomatic or may present with complications leading to sepsis. In this report, acquired diaphragmatic hernia and associated colonic perforation of a patient with a history of stab wounds was presented.

Abstract Background Although involvement of the urinary system is not uncommon, endometriosis in the kidneys is rare. To date, laparoscopic partial nephrectomy has been the preferred approach for managing renal endometriosis. Here, we report for the first time the results of laparoscopic removal of a renal capsular endometriosis in a malrotated kidney in an attempt to save the whole kidney parenchyma, in terms of feasibility and safety. Case presentation A 37-year-old female presented with periodic right flank pain associated with her menstrual cycle. On imaging, a malrotated right kidney and a hypodense irregular-shaped lesion measuring 30 * 20 * 15 mm were seen in the superior portion of the right perinephric space. Histologic evaluation of the ultrasound-guided biopsy was consistent with renal capsular endometriosis. The patient underwent laparoscopic surgery to remove the capsular mass while preserving the normal renal parenchyma. Pathological examination of the biopsy obtained during surgery was in favor of renal endometriosis. At 6-month follow-up, the patient’s pain had completely disappeared and no complications had occurred. In addition, imaging did not show any remarkable recurrence. Conclusion Renal endometriosis should be strongly considered as a differential diagnosis in female patients with a renal capsular mass and exacerbation of flank pain during menstruation. Based on our experience, with preoperative needle biopsy and clearing the pathology, laparoscopic removal of the mass in spite of renal anatomic abnormality is feasible and safe and thus could be considered as a possible treatment option.

Abstract Background Catamenial pneumothorax is characterized by spontaneous recurring pneumothorax during menstruation, which is a common clinical manifestation of thoracic endometriosis syndrome. There are still controversies about its pathogenesis. Case presentation A 43-year-old woman with a history of endometriosis came to our hospital due to recurring pneumothorax during menstruation. Uniportal Video-assisted Thoracoscopic Surgery (VATS) exploration was performed on the eve of menstruating. We thoroughly explored the diaphragm, visceral and parietal pleura: The lung surface was scattered with yellowish-brown implants; no bullae were found; multiple diaphragmatic defects were found on the dome. And surprisingly, we caught a fascinating phenomenon: Bubbles were slipping into pleural cavity through diaphragmatic defects. We excised the diaphragmatic lesions and wedge resected the right upper lung lesion; cleared the deposits and flushed the thoracic cavity with pure iodophor. Diaphragmatic lesions confirmed the presence of endometriosis, and interestingly enough, microscopically, endometrial cells were shedding with impending menses. After a series of intraoperative operations and postoperative endocrine therapy, the disease did not recur after a period of follow-up. Conclusion We have witnessed the typical signs of catamenial pneumothorax at the accurate timing: Not only observed the process of gas migration macroscopically, but also obtained pathological evidence of diaphragmatic periodic perforation microscopically, which is especially precious and confirms the existing theory that retrograde menstruation leads to diaphragmatic endometriosis, and the diaphragmatic fenestration is obtained due to the periodic activities of ectopic endometrium.

AbstractThe use of an ileal segment is a standard method for urinary diversion after radical cystectomy. Unfortunately, utilization of this method can lead to numerous surgical and metabolic complications. This study aimed to assess the tissue-engineered artificial conduit for urinary diversion in a porcine model. Tissue-engineered tubular polypropylene mesh scaffolds were used for the right ureter incontinent urostomy model. Eighteen male pigs were divided into three equal groups: Group 1 (control ureterocutaneostomy), Group 2 (the right ureter-artificial conduit-skin anastomoses), and Group 3 (4 weeks before urostomy reconstruction, the artificial conduit was implanted between abdomen muscles). Follow-up was 6 months. Computed tomography, ultrasound examination, and pyelogram were used to confirm the patency of created diversions. Morphological and histological analyses were used to evaluate the tissue-engineered urinary diversion. All animals survived the experimental procedures and follow-up. The longest average patency was observed in the 3rd Group (15.8 weeks) compared to the 2nd Group (10 weeks) and the 1st Group (5.8 weeks). The implant’s remnants created a retroperitoneal post-inflammation tunnel confirmed by computed tomography and histological evaluation, which constitutes urostomy. The simultaneous urinary diversion using a tissue-engineered scaffold connected directly with the skin is inappropriate for clinical application.

In this work, we discovered a new phenomenon—asymptomatic COVID-19 infection, or covert case, during the pandemic. All the 3 patients had a history of exposure, with no symptoms, and no abnormalities were found in computed tomography scan or lab tests. Except for case 2, the other patients’ severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) nucleic acid tests were negative. But their anti-SARS-COV-2 nucleocapsid antibody showed a dynamic trend, consistent with the process of virus infection and clearance. A growing number of asymptomatic or covert cases need more attention. Lack of surveillance may lead to another outbreak. We hope to demonstrate our cases to attract the attention of governments or health authorities that covert cases should be the focus as well.
