Case summary: A 7-year-old male castrated domestic shorthair cat was presented for treatment of a bilateral sacroiliac luxation (SIL). CT was performed and the data were extracted in a stereolithography (STL) file, after which a 3D-printed drill guide (3DPDG) was devised, using computer-aided design (CAD) software, and printed. Using an open surgical approach, the guide was used as an aid for drilling the sacrum. The ilial wings were drilled free-hand later and a transiliosacral pin (TP) was inserted to realign and stabilise the SIL. The cat exhibited an early return to normal limb function and a CT scan performed at the postoperative follow-up showed early signs of bone remodelling at the sacroiliac joint.
Relevance and novel information: To the authors' knowledge, this is the first report using a 3DPDG for implant placement in the feline sacrum without intraoperative imaging.

Case summary: A 6-year-old female spayed domestic shorthair cat was presented with a 7-month history of a subcutaneous mass on the dorsal nasal surface. A CT examination revealed the presence of a nasal dermoid sinus cyst with a nasal bone defect. The cyst was excised and an autologous fascia lata graft was used for reconstruction. The dorsal nasal bone was reconstituted and no compromise of respiratory function was reported in the long-term outcome. No short-term complications were observed at the 2-week follow-up. No long-term complications or recurrence were observed at the 2- and 12-month follow-ups. Fascia lata grafting appears to be an effective method for repairing a nasal bone defect after surgical excision of a nasal dermoid sinus cyst in cats. It is inexpensive and the tissue is easily harvested and provides good functional and cosmetic results.
Relevance and novel information: To the authors' knowledge, this is the first report that evaluates the effectiveness of repairing a nasal bone defect after dermoid sinus cyst excision in a cat using an autologous fascia lata graft.

Case summary: A 6-year-old castrated male domestic shorthair cat was evaluated for recurrent pleural effusion, atrial fibrillation and suspected congestive heart failure. During thoracocentesis, the fenestrated over-the-needle catheter became fractured and a catheter fragment remained in the patient's left pleural space. Later in the course of treatment, the patient acutely decompensated and was euthanized. There were no immediately observed complications associated with the retained catheter fragment.
Relevance and novel information: To the authors' knowledge, there are no reports of over-the-needle catheter fractures with retained pleural catheter fragments in veterinary medicine. Similar cases in humans have been successfully managed with and without removal of catheter fragments. In veterinary medicine, the decision to attempt removal of a catheter fragment must consider both the likelihood of related morbidity and the patient's ability to tolerate an invasive procedure.

Case summary: An 8-year-old male neutered domestic shorthair cat was presented with an acute onset of left thoracic limb lameness and a firm swelling on the lateral aspect of the left distal antebrachium. A CT scan of the left thoracic limb revealed an expansile osteolytic cystic bone lesion centred at the distal left ulnar metaphysis. Cytology from fine-needle aspiration was not consistent with neoplasia. The CT features and the cytology results were suggestive of a bone cyst. A distal partial ulnectomy with ulnar styloid process excision was performed as the biopsy method and as the treatment approach. Histopathology results were consistent with an aneurysmal bone cyst (ABC). Carpal instability was not detected after distal partial ulnectomy; therefore, a stabilisation method was not required. Limb function was excellent after surgery, with no lameness and no recurrence detected by the owner at 2, 6 and 24 weeks postoperatively. The veterinary examination at 12 weeks postoperatively confirmed the owner's outcome assessment.
Relevance and novel information: To the authors' knowledge, this is the first report describing a distal partial ulnectomy with ulnar styloid process excision in a cat. Despite disrupting the short ulnar collateral ligament, this technique provided excellent short-term limb function with no need for carpal joint stabilisation. This technique allowed for the complete excision of a distal ulnar ABC and avoided cyst debridement, which could be associated with haemorrhage, recurrence and malignant transformation. Distal partial ulnectomy should be considered for distal ulnar bone lesions in cats.

Case summary: A 4-year-old cat was presented with acute onset of lateralised neurological central nervous system (CNS) signs and seizures. Haematological and serum biochemical parameters were within normal limits. Imaging diagnostics revealed severe CT and MRI abnormalities of the right brain, similar to Dyke-Davidoff-Masson syndrome (DDMS) in human medicine. This syndrome includes cerebral hemiatrophy with compensatory calvarial hyperostosis and ventriculomegaly. Such changes have previously been reported only once in a single feline case of approximately the same age. In humans, DDMS is described as an embryonic and perinatal developmental disturbance or an acquired injury in early childhood.
Relevance and novel information: This case report shows that without further imaging diagnostics, congenital disorders can be overlooked in some rare cases of adult cats with later onset of their first clinical signs.

Case summary: An 11-year-old neutered male Turkish Angora cat was referred for obstructive feline lower urinary tract disease (FLUTD). On physical examination, the penis was curved at the tip and had a smaller than normal urethral opening proximal to the end, consistent with singular glandular hypospadias with a dorsal penile curvature. Because of its recurrent obstructive FLUTD history and inability to catheterise the urethra, a preputial urethrostomy (PRU) was performed. The PRU resolved the clinical signs with no clinical recurrence and no short- or long-term complications.
Relevance and novel information: To the authors' knowledge, this is the first description of singular glandular hypospadias in a cat. In addition, this is the first time feline hypospadias has been reported to occur with obstructive FLUTD and to be treated by preputial urethrostomy.

Case summary: A 2-year-old spayed female domestic shorthair cat presented with tetraparesis after being involved in a road traffic accident. Survey spine radiographs revealed a C2-C3 cervical subluxation, which was confirmed by a CT scan. Surgical stabilisation was performed using screws and polymethyl methacrylate (PMMA) via a ventral approach. A postoperative CT scan demonstrated correct implant positioning and good reduction of the subluxation. After surgery, the cat rapidly recovered to a neurologically normal status.

Case summary: A 5.5-year-old male neutered domestic shorthair cat was presented with a 2-year history of progressive chronic kidney disease. Abdominal ultrasonography revealed bilateral chronic renal degeneration, nephrolithiasis, cortical hyperechogenicity and infarction. Left orthotopic renal transplantation was performed using the Synovis vascular coupling system for end-to-end anastomosis of the renal arteries and veins. Two months after transplantation, renal values were elevated, and abdominal ultrasonography revealed hydronephrosis and hydroureter of the transplanted kidney. Fluoroscopic antegrade pyelography identified a proximal ureteral stricture. Proximal neoureterocystostomy was performed and renal values normalized postoperatively. The cat was re-evaluated for acute stranguria and severe azotemia 12 months later. Contrast-enhanced CT revealed severe hydronephrosis of the transplanted kidney, obstruction of the proximal ureter and adhesions to the urinary bladder. Upon exploration, retroperitoneal fibrosis was found covering the transplanted kidney. Given the clinical situation, a subcutaneous ureteral bypass device (SUB) was placed. Clinicopathologic analyses, trough cyclosporine levels, aerobic urine cultures and ultrasonographic evaluations of the transplanted kidney were monitored every 1-3 months. Patency of the SUB was reassessed every 3-6 months. At 15 months after placement, the SUB occluded due to kinking of the cystostomy catheter and was replaced. At 28 months after SUB placement, renal function and clinical status deteriorated, and the cat was euthanized.
Relevance and novel information: To the authors' knowledge, this is the first report of a SUB device being used for management of ureteral obstruction in a transplanted kidney in a cat.
病例摘要:患者是一只 5.5 岁的雄性阉割短毛猫,两年前开始出现进行性慢性肾病。腹部超声波检查发现双侧慢性肾脏变性、肾结石、皮质高回声和梗死。使用 Synovis 血管耦合系统对肾动脉和静脉进行端对端吻合,进行了左侧正位肾移植。移植两个月后,肾脏数值升高,腹部超声波检查发现移植肾肾积水和肾积脓。透视前行肾盂造影发现近端输尿管狭窄。对其进行了近端新输尿管囊肿切除术,术后肾脏数值恢复正常。12 个月后,该猫因急性绞窄尿和严重氮质血症接受了重新评估。对比增强 CT 显示移植肾出现严重肾积水,近端输尿管阻塞,膀胱粘连。经探查发现,腹膜后纤维化覆盖了移植肾。考虑到临床情况,患者被放置了皮下输尿管旁路装置(SUB)。每隔 1-3 个月对临床病理分析、环孢素谷值、需氧尿培养和移植肾的超声波评估进行一次监测。每 3-6 个月重新评估一次 SUB 的通畅性。放置 SUB 15 个月后,由于膀胱造口导管扭结,SUB 出现闭塞,因此进行了更换。放置 SUB 后 28 个月,该猫的肾功能和临床状况恶化,最终安乐死:据作者所知,这是首次报道使用 SUB 装置治疗猫移植肾的输尿管梗阻。

Case summary: A 2-year-old domestic longhair crossbred female cat was referred for a second opinion on a non-healing surgical wound after left eye enucleation. In addition to the left orbital lesion, ulcerative granular masses protruding from the left nostril and on the base of the left ear were noted. A diagnosis of cryptococcosis was established using histopathological examination and a latex cryptococcal antigen agglutination test. The cat was successfully treated with itraconazole.
Relevance and novel information: Cryptococcosis, commonly reported in Australia, western Canada and the western USA, is rarely reported in companion animals in Europe. This marks the first report of cryptococcosis in cats in Bosnia and Herzegovina, emphasising the need to raise awareness within the veterinary community, both local and regional, about this disease.

Case summary: A 4-year-old female neutered Scottish Fold shorthair cat was presented for further investigation of circling towards the right. MRI of the brain revealed an extensive, right-sided temporal muscle lesion with associated frontotemporal bone osteolysis, intracranial, extra-axial extension along the calvarial convexity with severe pachy- and leptomeningeal thickening and contrast enhancement, and an intra-axial space-occupying lesion in the right piriform lobe. The regional lymph nodes were moderately enlarged. Cytology of the right parotid lymph node and the temporal muscle was performed and histiocytic sarcoma (HS) was diagnosed. The owners elected euthanasia.
Relevance and novel information: HS of the central nervous system (CNS) is a very rare neoplastic condition in cats. Although a few case reports mention MRI, to our knowledge, the characterisation of MRI features of feline CNS HS have not been investigated in detail. Therefore, the aim of this case report was to describe the MRI characteristics in a feline HS involving not only the CNS, but also the fronto-temporal bone, temporal muscle and the regional lymph nodes. In particular, aggressive neoplastic bone invasion was a novel finding.
