Meningocele and meningoencephalocele of the skull are congenital deformities. These deformities, which are observed as cyst-like swellings in the median part of the skull cap, occur very rarely. The intracranial material protrudes through a spontaneous cavity, such as the anterior fontanelle , and they are classified as encephalocele, meningocele, or meningoencephalocele according to the cranial bifida.111 1122

Heartworm disease in dogs and cats is well known in many European countries including Bulgaria. There are furthermore studies confirming dirofilariosis in wild foxes and Canis aureus i reports about heartworm disease in domestic ferrets in our country.

History

A 5 year old male, entire, pet ferret (Mustela putorius furo), weight 0,9 Kg was presented with labored abdominal breathing. The owner reported reduced appetite, difficulty breathing and restlessness. The ferret was not able to sleep or lie down for more than few minutes.  The ferret was used to live mainly indoor and allowed during the summer to be outside in the garden, for just few hours during the day, to be exposed to natural sunlight.

Clinical presentation and collateral exams

On presentation ferret was lethargic with abdominal breathing and breathing rate up to 90/minute. There was clear subcutaneous edema more prominent on the front and hind legs and ventral part of the abdomen. Mucous membranes were pale, while CRT was not possible to be assessed. Heart rate ranged in between 120-180 bpm. Pulses were weak even if assessing on the femoral artery was difficult due to the subcutaneous edema. Abdominal palpation was unremarkable, lymph nodes were normal in size. Thoracic radiograph showed loss of detail into thoracic cavity consistent with pleural effusion. Thoracic US was performed confirming pleural effusion and one hundred and twenty ml of modified transudate was drained. Brief screening echocardiography showed normal left atrium and left ventricle and severely dilated right atrium containing double line hyperechoic objects suggesting the presence of few adult Heartworms. (Fig 1). Right atrium was larger than left atrium. Doppler study and any further detailed investigation of the heart were not possible to be performed due the fact ferret became aggressive and owner declined any sedation or anesthesia. Snap® HTWM Antigen test (Idexx) on blood yielded negative result and at fresh blood smear examination no microfilariae were possible to be identified.  Knott test was not possible to be performed due to limited amount of sampled blood.

Diagnosis

On the basis of echocardiography findings diagnosis of HW disease was done.  Negative HW antigen test was assumed to be due probably due to juvenile D.immitis worms and right atrium localization to the small size of pulmonary arteries as described in cats and ferrets.

Therapy and Follow up

The ferret was treated with Advocate® spot on >4kg (half tube), Furosemide 2mg/kg twice a day and Prednisolone 1mg/kg daily both of them orally. The ferret was stable on that therapy. He was eating and drinking well regain the normal body weight 1.5 kg. no breathing difficulties were reported. He was rechecked 35 days after initial presentation. Echocardiography showed right mildly dilated atrium but no presence of HW (Fig 2). Only 10 ml of fluid was drained from the thoracic cavity. From that time he was stable with no owners complain for 6 month. Suddenly he developed respiratory distress and on presentation was with cyanotic membrane. Pulmonary thromboembolism connects to HW disease was suspected Owner elected euthanasia and no more investigations. Necropsy was declined.

This case shows the in endemic area even indoor domestic ferrets may be infected by Dirofilaria immitis. and that the disease is difficult to be diagnosed and can lead to death. Suspicion about this problem and monthly chemoprophylaxis should be warranted in this situation as in dogs and cats.

Michael C2 fr et CCS 9Michael C2 fr et CCS 5Michael C2 fr et CCS 6Michael C2 fr et CCS 4Michael C2 fr et CCS 2It was maked a surgary to stabilize  cervical spine. Ten days after surgery Michael starts moving the pelvic limbs first and tries to stand on them. Twenty one days after surgary Micheal start to moving and thoracic limb  , but  have ataxia and destroys proprioception on his  four leg. Michael`s  recovery begin first with the hind limbs and then with the thoracic limbs .In human literature, the symptom in which the thoracic limb is in a dysfunctional state with minimal to no deficit in the pelvic limbs has been referred to as CCS (Central Cord Syndrome ). The spinal cords that travel to the pelvic limbs are minimally affected because the lesion is centralized in the cervical region, which only affects the thoracic limbs. In general, CCS has a good prognosis for functional recovery and its common etiology is traumatic disease in human medicine. CCS treatments with nonsurgical management include cervical spine restriction with a neck collar, rehabilitation followed by physical therapy and occupational therapy. Surgical management is provided for patients who cannot be treated by conservative management alone.

Clinical manifestations
Anorexia, cachexia, apathy, unilateral uveitis, normal temperature (38.5).
Clinical examination revealed all of the body (back, neck, abdomen and all the legs) nodules, which are not painful, mobile, not tempered and pigmented .The size of the nodules was variable from 1 to 5 centimeters.
Some nodules were ulcerated and bleeding, and still painless. Such formations are not observed in the nose and the ears, and the front part of the head.
Diagnostic approach:
We did not find any abnormalities on the X-ray examination of the chest and abdomen. A nodule was surgically removed by cutting.
Symptomatic therapy was appointed until the results of the histopathological examination:
Metoclopramide-0,5mg / kg
Ranitidine-4 mg / kg
Simethicone-65mg / rabbit
Meloxicam-1mg / kg
Enrofloxacin, 10 mg / kg
Intravenous infusion Hartman 4ml / kg / hour.
So designated therapy lasted about 10 days pending the results of pathological examination The condition of the animal slightly improved, which is expressed in phrases in appearance of appetite. The animal took small amounts of food.

Diagnosis:

Fibrosarcoma
The prognosis for this type of tumors is garded to poor. Because of poor condition of the patient and the prognosis owners decided to euthanased the rabbit.
