Context. Primary renal carcinoid tumours are rare. Their pathogenesis is unknown and the clinical presentation is similar to other renal tumours thus posing diagnostic dilemmas for clinicians.Objectives. To review the literature for case reports of primary renal carcinoids.Methods. Literature was extensively searched for case reports for primary renal carcinoids. Reports of metastatic carcinoids to the kidneys were excluded.Results. Approximately less than 90 cases of primary carcinoid tumours of the kidney have been reported in the literature. A total of 29 cases of primary renal carcinoids were reviewed. The mean age of presentation was 48 years (range 29–75) with both right kidney (48.3%) and left kidney (44.8%) being equally affected. 28.6% of the cases reviewed were diagnosed as an incidental finding. The mean followup time was 20 months with 73.1% of patients without evidence of disease after surgical treatment (radical or partial nephrectomy). Primary carcinoid tumours of the kidney are often well differentiated tumours. They are often misdiagnosed because of their rarity and similar presentation with other renal tumours.Conclusions. Primary carcinoid tumours of the kidney are rare tumours with an indolent course with frequent metastasis. Metastatic work up and followup is required in their management.

Introduction: Renal malignancies are common in children and they constitute 6-7% of all childhood tumours and nephroblastoma is the most common solid renal tumour in children. Currently, standardised institutional protocols in management of renal tumours in children are the norm. Large scale collaborative studies have started emerging, yet not much has been documented on the clinical presentation, pathology and outcome of solid renal tumours particularly in Africa. Aim: To review the presentations, pathology and the management-outcome of solid renal tumour in the centre in the absence of a coordinated protocol and multi-disciplinary collaboration. Materials and Methods: This was a nine and a half year longitudinal retrospective audit study of consecutive patients with solid renal tumours managed in a single tertiary centre: Nnamdi Azikiwe University Teaching Hospital Nnewi South-east Nigeria. It took place from January 2009-June 2018. Relevant data on demography, clinical features, management and outcome were extracted from records. Results were analysed using Statistical Package for Social Sciences (SPSS) version 22. Categorical data were tested for independence using Chi-square test and significant p-value set at <0.05. Results: Twenty two paediatric cases (15 males and 7 females) were included in the study. The mean age at presentation was 50.10±4.8 months. There were 15 males and 7 females. The mean duration of symptoms was 5.5 months; 21 (95%) presented with abdominal masses while 6 (27.3%) had gross haematuria and 13 (59%) were emaciated. Tumours involved left kidney in 15 (68%). Histological reports were available in 9 cases with nephroblastoma being the most common 6 (27.3%). The Commonest stage was stage 3, 10 (45%) and commonest procedure was nephroureterectomy, 11 (50%). Neo-adjuvant and adjuvant therapies were inconsistent. Conclusion: Late presentation, discordant treatment protocol, noncompletion of treatment and poor collaboration, were found to contribute largely to poor outcome of solid renal tumours in children in our setting. It is strongly believed that adoption of standard protocol and a multidisciplinary collaboration in management will improve records keeping and outcome.

Background: Carcinoid tumours are rare incidental finding in appendicectomy specimens.  Appendiceal carcinoid tumours are found in 0·3–0·9 per cent of patients undergoing appendicectomy. Methods: The medical records of all the patients who underwent consecutive appendectomies and the specimen sent to pathology department for biopsy in Sardar Patel Medical College, Bikaner, were retrospectively analysed. Detailed medical history was noted age, gender, indication for surgery, surgical procedure, tumour localization in the appendix, diameter of the lesion after fixation with formaldehyde, and overall incidence of tumour reviewed in detail Results: Out of the total 1382 patients, 2 (0.15%) were found to have histological evidence of carcinoid tumour of the appendix. Both were male patients with a mean age of 26.5 years (range: 13-40 years). Acute appendicitis was the clinical presentation for both patients. Open appendectomy was performed in one and laparoscopic in other one. Histologically, all tumours were located at the tip of the appendix with a mean diameter of 0.7cm (range: 0.6-0.8 cm). Conclusion: Carcinoid tumours of the appendix are extremely rare and invariably remain asymptomatic and are mostly discovered incidentally for appendicectomy done for other reasons, mostly acute abdomen. Carcinoid Tumour was diagnosed on histological examination of the removed appendix. The site and the size of the tumours rather than the depth are used for the assessment of the CT.

Orbital metastases from neuroendocrine tumour are rare entities. An incidental finding of orbital metastasis originating from neuroendocrine tumour is presented in the context of a comprehensive review of all case reports and series published to date. Demographics, clinical features, diagnostic work-up, treatment and prognostic data from the published literature are discussed. Ninety-five patients with orbital metastases from neuroendocrine tumours have been reported so far. Average age at presentation is 63.8 years (range 25–86), with no significant gender predominance. Gastrointestinal tract is the most common site of primary neuroendocrine tumours (62–85%). Typical presentation includes proptosis (80–85%) and diplopia (27–62%) in patients with known primary neuroendocrine tumour elsewhere. Histological subtype and presence of metastases seem to be important prognostic factors. Incidental finding of neuroendocrine tumour mestastases in asymptomatic patients with unknown primary disease is uncommon. In such cases, orbital biopsy and structural and functional imaging are essential to establish a diagnosis and stage the disease.

Context. Primary leiomyoma of the liver is a rare tumour with uncertain pathogenesis with similar presentation with other tumours of the liver. Little is known about its clinical course. Objectives. To review the literature for case reports of primary leiomyoma of the liver. Methods. Extensive literature search was carried out for case reports of primary leiomyoma of the liver. Results. A total of 36 cases of primary leiomyoma of the liver were reviewed. The mean age of presentation is 43 years with slight female sex affectation; females accounted for 55.6% of the cases reported in the literature. The average size of the tumour is 8.7 cm. 34.4% of the cases reviewed were incidental finding with the mean follow-up time of 33 months with most cases reporting no evidence of disease. Conclusions. Primary leiomyoma of the liver is very rare tumour with complex pathogenesis which remains largely unknown. Imaging of the tumour does not allow for a tissue specific diagnosis; hence histological review of the tissue specimen and immunohistochemical stains are imperative for diagnosis. Surgical resection is both diagnostic and curative. The diagnosis of primary leiomyoma of the liver should be considered as a differential in the management of liver tumours.

Abstract Background and Study Aims Primary intraspinal primitive neuroectodermal tumors (PNETs) account for ∼0.4% of all intraspinal tumors, but information about these tumors in the medical literature is limited to single case reports. We report four cases of primary intraspinal PNETs and present a systematic literature review of the reported cases. Materials and Methods We retrospectively reviewed and analyzed the clinical data of 4 patients with primary intraspinal PNETs who underwent neurosurgical treatment at our clinic between January 2013 and January 2020, and of 32 cases reported in the literature. Results The female-to-male ratio was 2.6:1. The mean patient age was 21.42 ± 15.76 years (range: 1–60 years), and patients <36 years of age accounted for 83.30% of the study cohort. Progressive limb weakness and numbness were the chief symptoms (accounting for ∼55.6%). The mean complaint duration was 0.89 ± 0.66 months for males and 2.72 ± 3.82 months for females (p = 0.028). Epidural (41.7%) was the most common site, and thoracic (47.3%) was the most frequent location. Most PNETs were peripheral, and magnetic resonance imaging (MRI) appearance was isointense or mildly hypointense on T1-weighted images and hyperintense on T2-weighted images. Homogeneous contrast enhancement was observed. The 1-year survival rate of patients who underwent chemoradiation after total or subtotal lesion resection was better compared with patients who did not undergo chemotherapy, radiotherapy, or total or subtotal resection. The modality of treatment was associated with survival time (p = 0.007). Conclusion Primary intraspinal PNETs mainly occur in young people with a female preponderance. In patients with a rapid loss of lower limb muscle strength and large intraspinal lesions on MRI, PNETs should be considered. Surgical resection and adjuvant radio chemotherapy are key prognostic factors.

Stage Renal Disease

The use of kidney grafts with aneurysmal disease involving the renal arteries for transplantation is very uncommon and relatively controversial. We herein present the case of a 52-year-old woman who volunteered to become a living-nonrelated donor; during the preoperative imaging workup, a computed tomography angiography revealed a 1.5-cm saccular aneurysm in the left kidney, while the contralateral renal artery was normal. We decided to utilize the left kidney for a 25-year-old male patient with end-stage renal disease, and following the ex vivo repair using the recipient epigastric vessels and saphenous veins, we completed the transplantation in the right pelvic fossa. The postoperative period was uneventful, and at 8 months from the surgery, the graft remains functional. The surgical repair of renal artery aneurysms followed by immediate kidney transplantation is a safe technique and an effective replacement therapy for recipients. The incidental finding of isolated aneurysmal disease in renal arteries should not exclude graft potential availability for transplantation following repair.

AbstractObjective:We present the first reported case of primary carcinoid tumour of the nasal septum.Method:Case report of our experience of a carcinoid tumour of the nasal septum. We discuss our clinical, radiological and pathological findings.Result:An 83-year-old woman presented with a history of left-sided nasal blockage. Clinical examination showed a unilateral, left-sided nasal polyp. Further imaging and histological analysis confirmed this to be a carcinoid tumour. Carcinoid tumours outside the gastrointestinal tract are rare. There have been reports of carcinoid tumours in the head and neck region, but no published cases occurring in the nasal septum. Our management involved wide surgical resection with regular follow up to monitor for recurrence and for the development of carcinoid syndrome. Four years from initial presentation, the patient remained free of the primary tumour and had displayed no signs or symptoms suggestive of carcinoid syndrome.Conclusion:To the authors' best knowledge, and after searching the world literature, the presented case represents the first report of primary carcinoid tumour of the nasal septum. Despite its rarity, this tumour should be considered as part of the differential diagnosis, as timely recognition and intervention are critical for successful treatment.

Introduction: We report our experience with laparoscopic management of ureteropelvic junction obstruction in horseshoe kidneys.Methods: Between February 2004 and March 2014, 15 patients with horseshoe kidneys and symptomatic ureteropelvic junction obstruction underwent laparoscopic management at our national referral centre. Depending on the anatomy and presence of obtrusive vessels or isthmus, we performed either dismembered, Scardino or Foley YV pyeloplasty, or Hellstrom vessel transposition. Patients were initially evaluated by ultrasonography, then diuretic scintiscan at 4 to 6 months, and followed by yearly clinical and sonographic exams.Results: This study included 11 male and 4 female patients between the ages of 4 to 51 year (average 17.7). The left kidney was involved in 12 patients (80%). Operation time was 129 minutes (range: 90–186), and patients were discharged within 2.8 days (range: 1–6). Although 8 (53.3%) patients had crossing vessels, of which 6 required transposing, the Hellstrom technique was solely used in 3 cases, of which notably 1 case failed to resolve and required laparoscopic Hynes within the next year. Eight cases underwent dismembered pyeloplasty, 2 Foley YV, 1 Scardino flap and 1 required isthmectomy and vessel suspension. At the mean follow-up of 60 (range: 18–120) months, the overall success rate was 93.3%.Conclusions: To our knowledge, this represents the largest report on laparoscopic pyeloplasty for horseshoe kidneys, providing the longest follow-up. Our findings confirm prior reports supporting laparoscopy and furthermore show that despite the prevalence of crossing vessels, transposition alone is seldom sufficient.

Work Up

We report on 2 patients in whom a cystic dilation of the conus medullaris was incidentally found at MR imaging carried out in the work-up for sciatica. The cysts were well circumscribed and had signal intensity identical to the CSF on both T1- and T2-weighted images. There was no evidence of contrast enhancement. None of the patients had specific symptoms related to the spinal cord. At surgery, no evidence of malignancy was seen in any of the patients. A benign cystic dilation, also called dilated ventriculus terminalis, occasionally can be seen in the conus medullaris as an incidental finding at thoracolumbar MR imaging. Unless the expansion per se indicates cyst drainage, these patients may be monitored by clinical and MR follow-up, avoiding surgery in a substantial number of cases.
