Purpose: To assess the arterial supply to hepatocellular carcinomas (HCCs) by inferior phrenic arteries (IPA). Material and Methods: A total of 126 consecutive cases of HCC were studied by contrast-enhanced CT and conventional arteriography. Blood supply from an IPA was suspected when the size of the HCC mass as seen on contrast-enhanced CT did not match the size of the tumor mass as seen on hepatic arteriography. Inferior phrenic arteriography was employed to confirm these findings. HCCs fed by the IPA were analyzed in terms of size, location, and history of prior treatment. Results: In 14 (11%) of the 126 cases, the tumor was found to have a blood supply from an IPA. Eleven of these tumors were located in segments 2 and 7. Three tumors, which had not been treated previously, had a blood supply from an IPA. Six tumors were almost exclusively fed by an IPA and were located in segments 7, 1, and 4. Conclusion: HCCs located in segments which form the bare area of the liver (S1, S2, S7) can be supplied by an IPA. This should be suspected when a lesion or part of a lesion is identified on contrast-enhanced CT but not on hepatic arteriography.

A rare case of malignant Brenner tumour of ovary manifesting with intestinal perforation due to colonic infiltration is elaborated in the present report. Brenner’s tumour accounts for 1%–2% of all ovarian neoplasms and malignant Brenner tumour is even rarer and only about 5% of Brenner tumours are malignant. A 62-year-old woman came to surgical emergency with 1-month history of abdominal pain, vomiting and constipation with a palpable mass in right iliac fossa. Abdominal radiograph was suggestive of colonic obstruction. Contrast-enhanced CT of the abdomen revealed cystic right ovarian mass of 10.2×8.8 cm2 with pneumoperitoneum. Exploratory laparotomy was done, which revealed mass arising from right ovary involving terminal ileum, cecum and ascending colon. Possibility of ovarian malignancy was kept. Patient underwent debulking surgery along with ileostomy and descending colon mucous fistula was created. Histology was compatible with malignant Brenner tumour of the ovary.

Primary Bone

Secondary osseous involvement in lymphoma is more common compared to primary bone lymphoma. The finding of osseous lesion can be incidentally discovered during the course of the disease. However, osseous metastases are infrequently silent. Detection of osseous metastases is crucial for accurate staging and optimal treatment planning of lymphoma. The aim of imaging is to identify the presence and extent of osseous disease and to assess for possible complications such as pathological fracture of the load-bearing bones and cord compression if the lesion is spinal. We are presenting two patients with treated lymphoma who were in complete remission. On routine follow-up contrast enhanced CT, there were new osteoblastic lesions in the spine worrisome for metastases. Additional studies were performed for further evaluation of both of them which did not demonstrate any corresponding suspicious osseous lesion. The patients have a prior history of chronic venous occlusive thrombosis that resulted in collaterals formation. Contrast enhancement of the vertebral body marrow secondary to collaterals formation and venous flow through the vertebral venous plexus can mimic the appearance of spinal osteoblastic metastases.

A 12-year-old, neutered male Rough Collie was referred because of a 5-day history of lethargy and respiratory distress. A pneumothorax was detected on a right lateral radiography at the referring veterinary surgeon. Contrast-enhanced CT of the thorax was performed and a severe bilateral pneumothorax with a collapse of the left cranial lung lobe was observed. The underlying cause of the pneumothorax could not be found at that point and an exploratory thoracotomy was performed. The left cranial lung lobe had several perforations and a lobectomy was achieved. A thrombus obliterating a medium calibre artery and associated severe surrounding pulmonary necrosis were detected histologically.

ABSTRACT Background and objectives Carcinoma expleomorphic adenoma (CXPA) is a rare neoplasm of the salivary gland which arises in the epithelial component of a pleomorphic adenoma. It is not automatically a high-grade tumor as is traditionally suggested and should be further qualified as to type, grade of carcinoma and extent, since intracapsular and minimally invasive tumors behave favorably. Setting Department of Head and Neck oncosurgery, Kidwai Memorial Institute of Oncology, Bengaluru. Case Report A 38-year-old female was referred to our outpatient clinic with history of a painless swelling in the left side of the neck since 8 years. Fine needle aspiration revealed carcinoma of the submandibular gland. Contrast enhanced CT revealed a large heterogeneously enhancing mass lesion in the submandibular fossa with the gland not seen separately. Lymph nodes in level Ib and II were enlarged. Excision of the tumor revealed CXPA with foci of high grade mucoepidermoid carcinoma. Conclusion CXPA should no longer be considered a specific diagnosis but a category in which the carcinoma should be typed, graded and quantitated to impart more prognostically and therapeutically relevant data for efficient management.

Enhanced Computed Tomography

A 46-year-old male with a history of hypertension visited the emergency department (ED) by ambulance complaining of sudden pain in the left side of his back. Ultrasonography (USG) performed at ED revealed splenic infarction along with occlusion and dissection of the celiac and splenic arteries without abdominal artery dissection. Contrast enhanced computed tomography (CT) revealed the same result. Consequently, spontaneous isolated celiac artery dissection (SICAD) was diagnosed. Because his blood pressure was high (159/70 mmHg), antihypertensive medicine was administered (nicardipine and carvedilol). After his blood reached optimal levels (130/80 mmHg), symptoms disappeared. Follow-up USG and contrast enhanced CT performed 8 days and 4 months after onset revealed amelioration of splenic infarction and improvement of the narrowed artery. Here, we report a case of SICAD with splenic infarction presenting with severe left-sided back pain and discuss the relevance of USG in an emergency setting.

Haemosuccus pancreaticus (HP) is an exceedingly rare cause of lower gastrointestinal (GI) bleed where pseudoaneurysm of the peripancreatic vessels ruptures into a pancreatic pseudocyst and blood travel through the pancreatic duct, thereby, draining into GI tract via the ampulla of Vater. 1 We present a case of 65-year-old African-American woman with a history of alcohol abuse presented with melena for 1 day. The contrast-enhanced CT of abdomen/pelvis showed peripancreatic vascular pseudoaneurysm with active haemorrhage. Angiography confirmed the diagnosis of HP and successful transcatheter embolisation was performed.

Adhesion band is a major cause of small bowel obstruction. Traditionally, the obtained results of computed tomography (CT) scan were indicative of adhesion band as an etiology for small bowel obstruction. However, adhesion is easily diagnosed today due to technological advances in radiology and high-quality multidetector CT. It is important to avoid the possible complications of bowel obstruction in the early and appropriate surgical intervention. This article is a report of a 45-year-old woman with abdominal pain and history of previous abdominal surgery. A contrast-enhanced CT scan showed multiple adhesion bands ensued the abrupt narrowing of bowel diameter and closed small-bowel loops obstruction. Furthermore, multiple bands were clearly observed and adhesiolysis was performed in the surgery.

Wooden Foreign Body

Intracranial wooden foreign bodies due to transorbital penetrating injury sparing orbital globe are relatively rare with no reported cases till date. A multidisciplinary approach with multiple imaging modalities is needed for preoperative surgical planning. In this case report, we report a case of 3-year-old male who presented to our emergency department with history of fall from 5 feet with no vision over right eye. ~2cm cut injury with sutures in situ was present over nasal ridge with pus discharge. CT scan head showed foreign body over temporal region. Right fronto-temporo-orbito-zygomatic craniotomy with removal of foreign body was done. Deep seated abscess seen over temporal fossa was evacuated and post-operatively intravenous antibiotics was continued. Contrast enhanced CT repeated on 15th post-operative day showed no remaining abscess or foreign body. The patient was discharged on oral antibiotics. The wound healed completely with no improvement of vision in 1-week follow-up. Keywords: brain abscess, orbito-cranial penetrating injury, wooden foreign body

Objectives: The characteristics of hypovascular and hypervascular well-differentiated hepatocellular carcinomas (HCCs) were compared in terms of tumor size, tumor markers and detectability by imaging modalities. Methods: Well-differentiated HCC nodules that are smaller than 2 cm (n = 27) were evaluated in 27 patients using histopathology and divided into 2 groups: hypovascular (n = 10) and hypervascular (n = 17). The diagnostic sensitivity of imaging modalities was then evaluated for efficiency in disclosing tumor size and tumor markers in the 2 types. Results: No difference was observed in tumor size and tumor markers between the 2 types; however, the sensitivity of contrast-enhanced CT, contrast-enhanced ultrasonography and arterioportal angiography was significantly different between the 2 types, whereas that by Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid enhanced magnetic resonance imaging (Gd-EOB-DTPA MRI) demonstrated no difference. Conclusion: Hypovascular HCC could be diagnosed by Gd-EOB-DTPA MRI in the hepatobiliary phase.
