This report describes the case of a 15-year-old female Arabian camel with omaso-abomasal adenocarcinoma showing prolonged anorexia with colic bouts leading to cachexia during the last 6 months. Hematological and biochemical findings were indicative of a moderate to severe haemorrhagic anaemia. Ultrasonographic examination revealed hyperechoic severely thickened (68 mm) and corrugated omaso-abomasal walls with heterogonous contents. Exploratory laparotomy revealed a large barrel-shaped mass with dense contents including parts of the compound stomach adhered to the parietal peritoneum. A definitive diagnosis was based on histopathological examination confirming the mass as an omaso-abomasal adenocarcinoma. Omaso-abomasal adenocarcinoma should be included in the differential diagnosis of abdominal tumours in camel.

We studied 72 buffalo with superficial swellings in the head (n=4), neck (n=5), chest wall (n=4), abdominal wall (n=28), limbs (n=16), gluteal region (n=8), perineal region (n=6) and udder (n=1). Ultrasonographically, the swellings varied according to type, duration, content and location. The clinical use of ultrasound to assess these superficial swellings allowed diagnosis of abscesses (n=21), hematomas (n=11), hernias (n=17), bursitis (n=13), urethral diverticula (n=6) and tumors (n=4). Ultrasonography could precisely discriminate each lesion type (sensitivity, 71–100%; specificity, 75–100%; odds ratio, 1.0–8.4; Confidence Interval, 74.2–20; and P value 0.001). The specificity for ultrasonographic evaluation of superficial swellings was 100% for hernias, urethral diverticula and tumors, whilst the lowest specificity was recorded for hematomas (75%) and abscesses (92%). In conclusion, ultrasonography provides a precise, non-invasive and fast technique for the evaluation, classification and subsequent treatment of a variety of superficial swellings in buffalo.

Background and Aim: Esophageal obstruction is a common occurrence and a serious condition in camels. This study aimed to assess the effects of mineral deficiency on esophageal obstruction rates in dromedary camels and describe their clinical presentation and treatment outcomes. Materials and Methods: Twenty-eight camels were allocated to two groups. Group 1 (control) was composed of 10 sound camels. Group 2 included 18 camels with esophageal obstruction which were based on clinical and imaging evaluations. Hematobiochemical examinations in control and affected camels were compared and statistically analyzed. Results: In camels with esophageal obstruction when compared with controls, hematological analyses showed significant increases (p < 0.05) in neutrophils, lymphocytes, and monocytes, along with significantly decreased total white blood counts. Aspartate transaminase, alanine transaminase, alkaline phosphatase, creatine phosphokinase, glucose, albumin, creatinine, and blood urea nitrogen concentrations were significantly higher in affected camels when compared with controls. Furthermore, gamma-glutamyl transferase, globulin, sodium, chloride, cobalt, iron, manganese, and selenium concentrations were significantly reduced. Affected camels were treated by stomach tube or surgery and were completely recovered, except for one camel with an esophageal fistula. Conclusion: A lack of trace elements could have a significant role in esophageal obstruction in dromedaries. Clinical, ultrasonographic, and hematobiochemical evaluations are useful for the accurate diagnosis, prognosis, and treatment of esophageal obstruction in camels. Keywords: animals, diagnostic imaging, esophagus, fistula, pathology.

The present study was designed to describe the clinical presentation of abdominal hernias and to evaluate the efficacy of polypropylene mesh in repair of such affection in camels. Twenty-six dromedary camels were included in this study on the basis of clinical and ultrasonographic evidence of abdominal hernia. Factors associated with prevalence and clinical findings of hernia were presented and hernioplasty using polypropylene mesh was evaluated as a surgical intervention. Out of 26 studied camels, abdominal hernia was prevalent in Wadeh camels than other breeds (17 vs 9, P<0.01). Camels <6 years of age exhibited more hernias than other age groups (18 vs 8, P<0.01). Moreover, females showed a significantly higher prevalence (19 vs 7, P<0.01) of abdominal hernia compared to males (26.9%, n=7). The sensitivity (96.8%) and specificity (93.1%) of ultrasonography for diagnosing hernia were higher in comparison to clinical examination (88.3%). At 3 weeks postoperatively, the clinical index score of 26 operated camels was significantly reduced in comparison with pretreated (22 vs 4, P<0.005). However, only 2 cases had recurrence of the hernia and 2 camels had slight swelling in situ. By the 6th month post treatment, all treated camels were completely recovered. In conclusion, the polypropylene mesh is a viable and consistent alternative effective treatment for abdominal hernias in camels. In addition, the clinical index scores and ultrasonography provide a precise paradigm for diagnosis and preoperative planning for abdominal hernias in dromedary camels.

Background and Aim: A healthy joint is an important structure for the proper movement of the camel limb. Intra-articular (IA) injection is frequently used in veterinary practice for diagnostic and therapeutic purposes of joint injuries. Thus, the current study aimed to describe the injection of the hindlimb joints in dromedary camels based on the anatomical and arthrographic-guided landmarks. Materials and Methods: Eighteen orthopedically sound adult camels (mean±standard deviation age: 78±12 months) of both sexes were included in this study. Three camels were euthanized to identify anatomical features in the hindlimb joints and related structures. IA injections were performed in the hindlimbs of 5 camel cadavers to evaluate the optimal IA injection site, which was confirmed by arthrography. The optimized IA injection technique was applied in 10 live camels and confirmed by arthrocentesis and arthrography. For each joint, injection criteria (number of attempts, difficulty of injection, and successful injection) were assessed, scored, and statistically compared to the other joints. Results: The summation of IA injection criteria scores was significantly higher (p<0.05) in the femorotibial, femoropatellar, tibiotarsal, fetlock, pastern, and coffin joints in comparison to the hip joint. Conclusion: Anatomical and arthrographic-guided techniques offer considerable advantages for the characterization of anatomical landmarks and selection of the appropriate IA injection site in the hindlimb in dromedary camels. Furthermore, a reference approach for camels was established that is different from the approach for cattle and horses.
