Right-Sided Ectopic Intrathoracic Kidney Associated With Symptomatic Bochdalek Hernia in an Adult Indian Female: Case Report and Review of Literature.

Bochdalek hernia is an inherited posterior lateral defect in the diaphragm that allows the abdominal organs to herniate into the thoracic cavity. In addition to being the most prevalent variety of congenital diaphragmatic hernia (CDH), it is also the type that is observed on the left hemithorax the majority of the time. Ectopic kidney is an uncommon condition, and the occurrence of ectopic intrathoracic kidney is even more uncommon, accounting for only a few of all the cases of renal ectopias. The occurrence of intrathoracic kidney associated with Bochdalek hernia is infrequent among adult individuals and is typically an incidental finding. A 52-year-old obese female patient presented to the pulmonology outpatient unit and reported experiencing the symptoms of coughing, wheezing, and difficulty in breathing since three years. A chest radiograph revealed an elevated dome of the diaphragm on the right side. A computed tomography (CT) of the chest revealed a defect in the posterior aspect of the right hemi-diaphragm with herniation of the right kidney and retroperitoneal fat into the right hemi-thorax. CT urography showed normal size and enhancement of the intrathoracic kidney with prompt excretion of contrast into the pelvicalyceal system. With regard to the small size of the hernia and considering the absence of complications on CT urography, a conservative treatment was proposed to the patient. The patient was followed up every year. There was no occurrence of renal complications during the follow-up period. When evaluating patients with 'elevated hemi-diaphragm' or thoracic 'mass', it is essential to check for the presence of intrathoracic kidney to avoid undesirable surgical procedures and image-guided biopsies.

Displacement of Abdominal Organs Into the Thoracic Cavity: A Rare Case of Adult Bochdalek Hernia.

Congenital diaphragmatic hernias are primarily found in infants and have a high mortality rate due to neonatal respiratory distress. The most common type of congenital diaphragmatic hernia is Bochdalek hernia, which occurs in the posterolateral diaphragm, with the left side being the most commonly affected. However, congenital diaphragmatic hernias are extremely rare in adults and are often misdiagnosed due to their subtle symptoms. Therefore, we suggest that a contrast-enhanced CT scan should be used for early screening and diagnosis in all patients with sudden severe pain or recurrent ambiguous symptoms in the chest and abdomen. This case report presents a rare occurrence of Bochdalek hernia in an adult male. The patient experienced nonspecific abdominal symptoms after eating. The hernia resulted in the displacement of the left kidney, the transverse colon of the splenic flexure, and most of the stomach into the thoracic cavity. This displacement led to atelectasis of the left lung, which reached three-fifths of its capacity. The patient underwent successful treatment using a combination of laparoscopy and open surgery. Follow-up CT scans conducted two weeks, three months, and one year later revealed a stable condition with no complications.

Prenatal diagnosis of intrathoracic kidney and adrenal gland in left-sided congenital diaphragmatic hernia.

A 29-year-old primigravida at 31 weeks of gestation was referred for intrathoracic kidney (ITK). Ultrasound revealed left kidney intrathoracic placement with an anteriorly positioned ectopic adrenal gland. Magnetic resonance imaging confirmed diaphragmatic interruption and colon herniation. A female neonate, delivered at 37 weeks, underwent successful thoracoscopic repair for a left Bochdalek hernia. Despite compression of the left lung, notably optimistic lung-to-head ratio (LHR) values were observed, correlating with favorable outcomes. This case underscores the rare occurrence of ITK, its association with Bochdalek hernia, and the importance of comprehensive prenatal evaluations.

Intrathoracic Kidney.

Intrathoracic kidney is a very rare finding, representing less than 5% of all renal ectopias. Because of the location of the liver, thoracic kidney on the right side is much less common than thoracic kidney on the left side. Although an increasing number of case reports are being published in the literature, few describe the impact of the ectopia on kidney function. We report the case of a woman with intrathoracic right kidney and chronic kidney disease that was initially misdiagnosed as pneumonia because of its presentation on chest x-ray. We highlight the need to including this condition in the differential diagnosis[2] as the literature rarely links it to changes in kidney function. LEARNING POINTS: Intrathoracic kidney is an extremely rare condition that should be considered in the differential diagnosis of intrathoracic masses.There is a lack of literature on this type of kidney ectopia and its consequences in asymptomatic individuals.

Thoracic kidney nephrectomy due to recurrent Bochdalek hernia in an adult / Nefrectomía de riñón intratorácico derecho debido a recurrencia de hernia de Bochdaleck en un paciente adulto

Congenital diaphragmatic hernia incidence is one in 3000 live births, Bochdalek hernia occurs through a posterolateral defect. It is very rare in adults. We present a case of late relapsed one diagnosed in an adult male. He underwent an open intervention of Bochdalek hernia at first day of life and required reintervention at seventh month due to recurrence. Now, computerized tomography scan demonstrates a right diaphragmatic defect with intrathoracic hydronephrotic kidney.

Congenital Diaphragmatic Hernia With Kidney and Spleen Herniation in the United Arab Emirates: A Case Report.

Congenital diaphragmatic hernia (CDH) is a severe congenital anomaly that leads to herniation of abdominal viscera to the chest, which presents with respiratory distress shortly after birth. Spleen herniation is a rare finding, and kidney herniation is even more exceedingly rare. We hereby report a case of a neonate that developed severe respiratory distress secondary to CDH. After confirming the diagnosis with chest and abdominal X-ray and initial stabilization, the patient underwent laparotomy, which revealed a large diaphragmatic defect with herniation of the ileum, colon, spleen, and left kidney. Contents were reduced to the abdomen, and the defect was repaired. The patient had a complete recovery with no complications. After reviewing the literature, we noticed the paucity of data in the Middle East region regarding the disease burden and the increased rate of complications with delayed diagnosis. Therefore, we believe that this case, which was presented in the United Arab Emirates with kidney and spleen herniation and received prompt management, is a valuable addition to the literature.

Ectopic right thoracic kidney associated with Bochdalek hernia as the cause of diagnostic confusion.

A 61-year-old man who was a psychiatric patient and an alcoholic was admitted to hospital after a fall in his bathroom. He showed signs of hemorrhagic shock, and CT scans showed the presence of the right kidney and part of the right retroperitoneum in the right hemithorax, surrounded by liquid. Surgery showed that the right hemidiaphragm was intact and that no intraabdominal viscera prolapsed into thoracic cavity. The bleeding in the right retroperitoneum was evacuated. The surgical report also stated that "the right kidney and ureter were explored and no injuries or active bleeding were found". The patient died the third day after admission. Autopsy revealed a livid swelling covered with parietal pleura in the right half of the thoracic cavity, behind the costophrenic sinus, about 20 × 15x12 cm in size, filled with about 1500 ml of blood, with ectopic right kidney in the right half of the thorax, slightly rotated posteriorly and downwards. The kidney was smaller (80 g in weight), compared to the normally positioned enlarged left kidney (300 g). The right hemidiaphragm was also intact with small Bochdalek's foramen behind the posterior edge, with communication between the right retropleural and retroperitoneal spaces, through which intact elongated right renal artery (15 cm), vein (14 cm) and ureter were passing. The cause of death was hemorrhagic shock due to retroperitoneal bleeding, with coagulation disorder as possible contributing factor. Intrathoracic kidneys may pose many diagnostic and management dilemmas for clinicians and pathologists. Association between a Bochdalek hernia and an intrathoracic renal ectopia is very rare and may be confusing for doctors in different clinical situations.

A missing kidney and a hidden congenital diaphragmatic hernia.

Congenital intrathoracic kidney (ITK) is a rare condition, which is usually discovered incidentally in asymptomatic children who do not need any intervention. However, it may be associated with congenital diaphragmatic hernia (CDH), in which case it requires urgent surgical intervention. We present a case of prenatally diagnosed ITK associated with a left CDH that was operated on day 5 of life. The neonate is currently well at 15 months of age.

Urgent surgical repair of symptomatic Bochdalek hernia containing an intrathoracic kidney.

Bochdalek hernias rarely contain an intrathoracic kidney, and there are few reports of their operative repair. A woman presented with progressive dyspnoea limiting her quality of life. Imaging showed a Bochdalek hernia containing omentum, large bowel and the left kidney. The woman was unexpectedly admitted to the intensive care unit with respiratory failure secondary to gallstone pancreatitis whilst awaiting elective repair of her hernia. Surgical repair of the hernia was performed via laparotomy with cholecystectomy to treat both problems. The woman recovered well and is independently mobile without any exertional dyspnoea.

Ectopic Intrathoracic Kidney Associated with Ipsilateral Ectopic Spleen and Diaphragmatic Hernia in a Pediatric Patient: A Case Report.

Background: Intrathoracic kidney is the rarest form of an ectopic kidney that is usually accompanied by left congenital diaphragmatic hernia (CDH) (Bochdalek hernia), the association of which with other anomalies is rare. Case Presentation: Herein, we describe a case with a diagnosis of an intrathoracic kidney associated with the ectopic spleen and diaphragmatic hernia diagnosed during imaging studies for urinary tract infections (UTIs). This study reports an 11-month-old male case with a history of CDH and several episodes of UTIs. A kidney ultrasound revealed that the left kidney and spleen were located in the thoracic cavity. Despite intrathoracic lying of the left kidney, there was no vesicoureteral reflux. Technetium-99m dimercaptosuccinic acid scan reported a highly positioned left kidney . Conclusion: With the consideration of a pediatric literature review among patients with intrathoracic ectopic kidney, our case was special and notable since it was the first neonate who had an association of intrathoracic spleen and kidney in the same side with a delayed diagnosis. The main point of this case was that radiologists should consider thoracic kidney a differential diagnosis of unilateral renal agenesis when there is a history of diaphragmatic hernia.

Congenital Diaphragmatic Hernia with Intrathoracic Renal Ectopia: Thoracoscopic Approach for a Complete Anatomical Repair.

Congenital diaphragmatic herniae (CDH) with associated intrathoracic ectopic kidneys are rare congenital anomalies, with a reported incidence of only 0.25%. The authors report a case of a 24-day-old baby girl who was diagnosed with a left-sided CDH on a chest X-ray taken for pneumonia. Computed tomography scan showed CDH hernia, containing small and large bowel and whole left kidney with adrenal gland. Thoracoscopic reduction in the bowel, kidney, and adrenal gland into the abdomen and primary closure of the defect was achieved with no complications. During investigation of the child, it was discovered that her maternal aunt had also had a left-sided congenital diaphragmatic hernia containing the kidney, which was treated via open surgery after birth; she subsequently developed renal cell carcinoma and required radical nephrectomy of that kidney during her third decade.

Bochdalek hernias associated with intrathoracic kidney: A case report and systematic review of outcomes including renal function.

BACKGROUND: An intrathoracic kidney is a very rare form of ectopic kidney. Though increasingly recognized in the literature, impact on renal function is less well described. We report the case of a 67-year-old South Asian gentleman who presented with intrathoracic kidney and chronic kidney disease. We carried out a systematic review of the available literature on intrathoracic kidney, in order to characterize the typical clinical features, and describe likely clinical course and possible renal and extra-renal complications associated with this form of ectopia. MATERIALS AND METHODS: A structured search using PubMed identified all relevant published case reports from 1988 to 2018, with search restricted to papers in English, and to adult cases only (> 18 years of age). 124 records were identified, and after screening for eligibility, 34 case reports were analyzed. RESULTS: Median age was 53.5 years, with no gender predominance. 68% (27/34) of cases were symptomatic. 29% (10/34) had a significant complication associated with their intrathoracic kidney, with 3 cases with either documented chronic or end-stage kidney disease. 26% (9/34) required surgical intervention. CONCLUSION: Though previously regarded as a benign entity, results from our systematic review, bearing in mind susceptibility to publication bias, suggests an appreciable risk of symptoms, complications, and in the minority a risk to kidney function. We recommend close biochemical and imaging surveillance of affected patients, with low threshold for intervention in those with renovascular stenosis, reflux, or hydronephrosis.

Bilateral thoracic kidneys combined with inferior vena cava located behind the anterior abdominal wall: A case report and review of literature.

Ectopic thoracic kidneys are the rarest form of renal ectopia. Moreover, congenital abnormality of a primary anterior inferior vena cava (IVC) located behind the anterior abdominal wall is extremely rare. To date, only one such case has been reported. Herein, we report a rare case of a 55-year-old Chinese male with bilateral thoracic kidneys combined with an anterior IVC, a malformed liver, and a large-round-folds navel. The classification, clinical characteristics, and management options of a thoracic kidney was also summarized by literature review. To our best knowledge, the simultaneous detection of such multiple complex abnormalities has not been reported.

"What Goes Up Must Come Down": Laparoscopic Retrieval of a Migrated Intrathoracic Kidney and Repair of Recurrent Symptomatic Diaphragmatic Hernia.

Background: Congenital diaphragmatic hernia is a rare condition describing a developmental defect of the diaphragm. It is managed surgically in the neonatal period by reduction of the herniated viscera followed by repair of the defect. We present a laparoscopic repair of a Bochdalek diaphragmatic hernia recurrence with retrieval and nephropexy of a migrated kidney with reduced function from its ectopic thoracic position. The complexities of managing this rare occurrence and lessons from this surgical challenge are discussed. Case Presentation: A 21-year-old primigravida presented with a 3-day history of right upper quadrant pain and increasing dyspnea. Of note, she had undergone a congenital right-sided diaphragmatic hernia repair as an infant. An MRI revealed a recurrent diaphragmatic defect with ectopic migration of the right kidney and bowel into an intrathoracic position. Due to worsening dyspnea, she underwent prompt laparoscopic repair of her recurrent diaphragmatic hernia. Subsequently, she underwent a planned cesarean section to control her intra-abdominal pressures and reduce the risk of hernia repair failure. Conclusion: Raised intra-abdominal pressures during pregnancy in patients with prior congenital hernia repair can result in recurrence and migration of peritoneal and retroperitoneal contents into the chest. In cases of renal unit migration, the primary concern must be to restore the anatomical position of a functioning kidney. Multidisciplinary specialist involvement in a tertiary referral base is crucial to an effective outcome.

Right ectopic intrathoracic kidney: Unusual clinical presentation in a young patient affected by scrotal varicocele.

Intrathoracic kidney is a partial or complete displacement of the kidney above the hemidiaphragm into the mediastinal compartment of the thorax. It is usually seen as an incidental finding discovered on chest radiograph or abdominal ultrasound. However computed tomography consents the correct detection of intrathoracic masses and defines their shape, size, and extent. We here report a case of ectopic thoracic kidney in a 22-year-old man who had a long history of scrotal discomfort associated with right varicocele. Frequently, this ectopia does not affect renal function and the stretched ureter provides good drainage. In literature, a small number of cases shows that varicocele is a possible mode of presentation of kidney tumors, but this is the first case of varicocele secondary to intrathoracic kidney ectopia.

Prenatal diagnosis of right-sided diaphragmatic hernia and ipsilateral intrathoracic kidney in a female fetus: a rare observation.

Congenital diaphragmatic hernia is a rare congenital malformation, as well as kidney ectopia. Among kidney ectopias, the intrathoracic one is the rarest. Those malformations concern more frequently boys, and affected more the left than the right side. Their association is poorly reported in the literature. We report the rare case of an early sonographic prenatal diagnosis of intrathoracic kidney at 22 weeks of gestation in a female fetus, completed on the follow-up by the diagnosis of an associated diaphragmatic hernia at 33 weeks of gestation. If chest mass is diagnosed prenatally or in neonate, ITK should be considered in a differential diagnosis, all the more if the ipsilateral renal fossa is empty. An associated DH should be searched if ITK is confirmed. Isolated ITK usually requires no specific treatment, in contrast with ITK associated with DH.

Transabdominal robotic repair of a congenital right diaphragmatic hernia containing an intrathoracic kidney: a case report.

Bochdalek diaphragmatic hernia is a rare condition and is typically diagnosed prior to adulthood. Furthermore, right-sided defects are also uncommon due to the location of the liver, but can contain colon, omentum, small bowel, or rarely the kidney. Minimally invasive laparoscopic and thoracoscopic diaphragmatic hernia repairs are associated with improved outcomes when compared to open approaches-recently, robotic-assisted repairs have been performed in children with no morbidity and minimal complications. We report a case of an 80-year-old female who presented with an enlarging right-sided Bochdalek hernia containing an acquired intrathoracic kidney that was repaired using a robotic-assisted laparoscopic transabdominal approach with mesh placement. In this case, the robotic platform's advantages included excellent visualization of the posterolateral defect and efficient suturing during mesh placement. This approach is a viable option for skilled minimally invasive surgeons; however, further studies are warranted to investigate its utility in the management of diaphragmatic hernia repair.

Ectopic Intrathoracic Kidney Presenting as Recurrent Pneumonias in a 1-year-old Infant: A Case Report.

Ectopic intrathoracic kidney is a rare congenital anomaly, representing less than 5% of all renal ectopias. Most cases are discovered in asymptomatic adult patients undergoing imaging exams for unrelated reasons. Less than twenty cases of thoracic kidneys in the infant group have been reported in the literature, mostly comprising asymptomatic patients. Herein, we report a case of an 18-month-old boy with recurrent pneumonia episodes who was found to have a right-sided intrathoracic ectopic kidney. A brief literature review addressing the pathogenesis, prognosis, and treatment of this condition is also presented.
